The Network Dashboard

The default layer model representation has many benefits - for starters, the model is consistent across applications, thus ensuring a shorter learning curve for the users. Secondly, from depicting the current state of an application to indicating the current issues related to that application, the layer model page serves as the most reliable platform for providing detailed, real-time information related to current application performance. Lastly, and most importantly, the layer model page automatically correlates the performance across all the layers of an application, and precisely indicates where the performance issues related to that application originated - at the host level? the network/TCP level? or the application level? - in short, from a correlation standpoint, the layer model is ideal.

On the flip side, though the layer model can accurately point to the 'problem layer', the actual 'problem' itself is hidden inside the tests, measures, and detailed diagnosis information mapped to the layer; getting to the root-cause of an issue using the layer model therefore, involves a little time and a few mouse clicks! Finally, while its true that the layer model page can clearly depict the current state of a component, it merely provides the means to launch those interfaces that reveal past performance/problems related to that component; this implies that when it comes to analyzing historical performance and deducing performance trends, problem patterns, and potential anomalies, the layer model page offers little help.

To eiliminate these shortcomings, eG Enterprise now offers specialized dashboards along with the unique monitoring model of every application that is monitored. Once the problem layer is indicated by the layer model, you can switch to one of these dashboards to receive in-depth insights into the performance of the problem layer(s), and thus troubleshoot the issue at hand better. Typically, these dashboards facilitate the following:

Serve as a single, central console that not only depict the current state of a layer, but also instantly indicate the root-cause of issues pertaining to that layer, thereby enabling administrators to go from problem effect to the problem source in no time!

Combine both raw and graphically represented data, and facilitate an in-depth analysis of not just live performance, but also the historical performance of a particular layer, thus shedding light on potential anomalies;

Aid administrators in effectively analyzing the past trends in the performance of a layer, so that they can easily forecast future performance;

Enable service level audits on-the-fly, and thus help administrators accurately determine when a layer slipped from the desired performance levels.

By default, the layer model representation of every application is accompanied by a System Dashboard and a Network Dashboard. In addition to these dashboards, a few selected applications are provided with an Application Dashboard as well.

Clicking on the Network tab page, will reveal the Network Dashboard, which allows you to zoom into the performance and problems pertaining to the Network layer and related layers of a target application/device. Using this dashboard, you can:

Determine whether/not the application/device currently experiences / has in the past experienced network-related issues;

Accurately identify the network parameters that are currently failing;

Understand the current network configuration;

Analyze network performance over time, study the trends in network connectivity and usage, and accurately deduce problem/performance patterns.

Identify persistent problems with network health and the network-related layers responsible for the same;

The contents of the Network Dashboard and the subsystems it offers for analysis could slightly vary depending upon whether the target is an application or a network device. While the Network Dashboard of a host/application enables you to focus on both the network and TCP connections handled by the target, the same for a network device sheds light on the network connectivity of the device and the traffic handled by the network interfaces supported by the device. Accordingly, the Network Dashboard of an application/host offers Network and Tcp as its Subsystems, and that of a network device offers Network and NetworkInterfaces as its Subsystems. If the target application is a Windows-based one, then the Subsystems list will include an additional WindowsInterfaces option, which provides the performance information related to the traffic handled and bandwidth used by the network interfaces supported by the system.

The Network Dashboard of Hyper-V servers on the other hand, will additionally support a Hyper-V Switches and a Hyper-V Network Adapters sub-system. Similarly, the Network Dasboard of a vSphere/ESX server will include an additional VirtualNetwork sub-system.

Overview

By default, the Overview option is chosen from the Subsystem list. As the name suggests, the Overview dashboard provides an all-round view of the network health of a target application/device.

For a monitored host, the Overview dashboard reveals the following:

Using the Current Network Alerts section, you can instantly understand how many problems of what severity are currently affecting the health of the Network layer of the device. Clicking on a non-zero number here will open a window, which will list the network-related alarms of the priority clicked on.

Clicking on an alarm here will introduce a Alarm Details section in the Alarms window that will provide additional details pertaining to that alarm - such details include the test that reported the problem, the site (if any) affected by the problem, the problem layer, and the Last Measure value.

To determine the quality of the network links leading to the network device during the last 1 hour, view the History of Events section; this section displays a bar graph that provides a quick look at the number and priority of network problems faced by the target application during the last 1 hour. In addition, the average and maximum duration for which these issues remained open will also be available in this secton; this enables you to assess the efficiency of your administrative staff. As already mentioned, by default, the event history provided by the dashboard pertains to the last 24 hours. To override this default setting, open the DASHBOARD SETTINGS window by clicking on the icon at the top of the dashboard, select Event Distribution from the Default timeline for list, and then pick a Timeline. Finally, click the Update button.

For more details about the historical problems, click on any of the bars in the bar graph. The Event History page, will then appear, listing all the network-related events that were captured by the eG agent on the target network device, during the last 24 hours (by default). This information enables you to understand what type of problems were faced by the target device during the default timeline, and how long each problem remained.

Click on the Back to Dashboard link at the right, top corner to return to the Network Overview dashboard and focus on the At-A-Glance tab page in the dashboard. For a network device, this tab page reveals, at a single glance, the current network health, network latencies (if any), and the status of the network interfaces supported by the device. Besides enabling you to accurately detect sudden changes in the state of the device, this section also helps you nail the root-cause of this state change; moreover, you can even identify network interfaces that are performing poorly, with the help of this section.

You can use the Current Nework Status section in the At-A-Glance tab page to know how problem-prone your network is; the pie chart here indicates the percentage of current network-related measures that are in varying states of activity. Clicking on a slice in this pie chart will once again lead you to the Event History page.

This will be followed by dial charts and digital displays that will update you with the status of a pre-configured list of metrics; these metrics reveal the following:

Whether the network device is currently available over the network or not;
Has the device experienced any loss of data packets? If so, to what extent?
How long has the device been up? Was the device rebooted anytime after it was started?
Was there any delay in connecting to the device? How significant is the delay? - in the event of a high network latency, you can use the Routers by HopDelay table to figure out where - i.e., at which hop - the maximum delay occurred.
What is the maximum rate at which data is currently transmitted and received by the network interfaces supported by the device?
What is the maximum speed at which the network interfaces currently operate?

If need be, you can add more metrics to be represented as dial charts or digital displays, or can remove one/more of the dial/digital charts that pre-exist in the dashboard. For this purpose, do the following:

Click on the icon at the top of the Network Dashboard. In the Dashboard Settings window that appears, select Network from the Module list.
Next, select the Overview option from the Sub-System list to indicate that changes need to be effected on the dashboard of the Overview sub-system.
To add measures for the dial graph, pick the Dial Graph option from the Add/Delete Measures for list. Upon selection of the Dial Graph option, the pre-configured measures for the dial graph will appear in the Existing Value(s) list. Similarly, to add a measure to the digital display, pick the Digital Graph option from the Add/Delete Measures for list. In this case, the Existing Value(s) list box will display all those measures for which digital displays pre-exist.
Next, select the Test that reports the said measure, pick the measure of interest from the Measures list, provide a Display name for the measure, and click the Add button to add the chosen measure to the Existing Value(s) list. Note that while configuring measures for a dial graph the 'Measures' list will display only those measures that report percentage values.
If you want to delete one/more measures from the dial/digital graphs, then, as soon as you choose the Dial Graph or Digital Graph option from the Add/Delete Measures for list, pick any of the displayed measures from the Existing Value(s) list, and click the Delete button.
Finally, click the Update button to register the changes.

Note:

Only users with Admin or Supermonitor privileges can enable/disable the system, network, and application dashboards, or can customize the contents of such dashboards using the Dashboard Settings window. Therefore, whenever a user without Admin or Supermonitor privileges logs into the monitoring console, the button will not appear.

Clicking on a dial chart/digital display in the dashboard will lead you to the layer model page that will reveal the exact layer and test that reports the measure represented by the dial chart/digital display.

If users are experiencing delays while connecting to the component via the network, then you can use the Routers by Hop Delay (ms) section to nail the root-cause of such a network latency. This section details the hop-by-hop connectivity and delay, and thus help isolate the exact hop at which a network delay occurred.

Note:

If you have configured more than two dial charts for the Network Overview dashboard using the Dashboard Settings window, then the Routers by Hop delay (ms) section will not appear in the At-A-Glance tab page.

The Network Configuration section displays the current network configuration, and enables you to ascertain whether a change in configuration could have contributed to the network problems at hand.

This section typically displays a default set of configuration metrics. If need be, you can add more network configuration information to be displayed in this section, or can even remove existing configuration details from this section. To achieve this, do the following:

Click the button at the top of the dashboard.
The Dashboard Settings window then appears. From the Module list, pick Network, choose Overview as the Sub-System, and then select Network Configuration from the Add/Delete Measures for list.
The Existing Value(s) list wll then display all the measures that pre-exist in the Network Configuration section. If any of these measures need to be removed, simply select the measure(s) from the Existing Value(s) list, and then click the Delete button. Finally, click the Update button.
On the other hand, to add a new measure to this section, select the Test that reports the measure, then pick the Measure, provide a Display name for the measure, and then click the Add button. Finally, click the Update button.

Note that the Network Configuration will appear only if your eG license allows Configuration Management; if not, then this section will display a bar chart indicating the current status of the Network layer of the host, in terms of the percentage of time the host has been in normal/critical/major/minor/unknown states.

Adjacent to the network configuration, the dashboard provides a Key Performance Indicators (KPI) section, which tracks the performance of those network-related metrics that are identified as 'critical' indicators of network performance. These metrics are pre-configured, but this default configuration can be changed by the user using the Dashboard Settings window. New KPIs can be added, and one/more existing KPIs can be removed, if need be. To achieve this, do the following:

Click the button at the top of the dashboard.
The Dashboard Settings window then appears. From the Module list, pick Network, choose Overview as the Sub-System, and then select Performance Indicator from the Add/Delete Measures for list.
The Existing Value(s) list wll then display all the measures that pre-exist in the Key Performance Indicators section. If any of these measures need to be removed, simply select the measure(s) from the Existing Value(s) list, and then click the Delete button. Finally, click the Update button.
On the other hand, to add a new measure to this section, select the Test that reports the measure, then pick the Measure, provide a Display name for the measure, and then click the Add button. Finally, click the Update button.

By closely monitoring the status of these metrics, you can be instantly updated with critical network issues. Clicking on a measure listed in the Key Performance Indicators section will lead you to the Layer Model tab page of the application, which reveals the exact layer and test that reported the measure.

This way, from a single console, you can receive rapid, real-time updates on the overall network status of your network devices, and instantly identify the root-cause of such network-related anomalies. In order to zoom into the performance of network interfaces in particular, switch to the Details tab page by clicking on it.

The Details tab page provides a default set of bar charts, each of which lists the top-10 network interfaces in a particular performance arena. Using these default bar charts, you can instantly figure out the following:

Which network interface is currently available?

Which network interface is operating with the maximum speed?

Which network interface is utilizing the maximum bandwith?

The incoming and outgoing traffic to which network interface is very high currently?

If need be, you can override this default setting to add more comparison graphs to the Details tab page or remove one/more existing bar graphs from this tab page. To do this, follow the steps given below:

Click the button at the top of the dashboard.

The Dashboard Settings window then appears. From the Module list, pick Network, choose Overview as the Sub-System, and then select Comparison Graph from the Add/Delete Measures for list.

The Existing Value(s) list wll then display all the measures for which comparison graphs pre-exist in the Details tab page. If any of these measures need to be removed, simply select the measure(s) from the Existing Value(s) list, and then click the Delete button. Finally, click the Update button.
On the other hand, to add a new measure to this tab page, select the Test that reports the measure, then pick the Measure, provide a Display name for the measure, and then click the Add button. Finally, click the Update button.

In addition to the default/user-configured bar graphs, the Details tab page includes a Routers by HopDelay bar chart that graphically depicts the hop-by-hop delay, so that you can easily identify the hop at which significant delay has occurred.

By default, all the bar charts in the Details tab page pertain to the current period. However, sometimes, you might want to go back in time, so as to investigate a past problem and identify its source. For this purpose, click on the corresponding bar chart in the Details tab page.

The enlarged bar chart, by default, lists all the network interfaces that are supported by the target server/network device. To view the performance of a specific set of interfaces alone, select a TOP-N or LAST-N option from the Show list. To know which network interface had contributed to a problem situation in the past, click on the Compare History link, and alter the Timeline of the graph.

Though the Details tab page enables you to focus on both the current and past performance of network interfaces, to proactively detect any type of potential anomaly, the past performance of the network in its entirety needs to be analyzed. For this purpose, switch to the History tab page by clicking on it.

The measure graphs for a pre-configured set of performance metrics, then appears ; these graphs, which are typically plotted for a default period of 24 hours, indicate the following:

Were there any breaks in the availability of the network connection to the device during the last 24 hours?
Were any data packets lost in transit during the last 24 hours?
Was any significant delay detected in connecting to the device during the last 24 hours?
How was the data traffic to and from the device during the last 24 hours?
Were any TCP connections dropped by the target during the default timeline?
How busy was the target, in terms of TCP connections, during the default time period?

To analyze network performance over longer time periods, you can change the graph timeline by clicking on the Timeline link. In addition, you can click on the graph to expand it and view its contents clearly. You can even alter the default timeline (of 24 hours) of these measure graphs by following the steps given below:

Click the button at the top of the dashboard to invoke the Dashboard Settings window.
Select the History Graph option from the Default timeline for list.
Set a different default timeline by selecting an option from the Timeline list.
Finally, click the Update button.

If need be, you can view Summary graphs in the History tab page to figure out the percentage of time (during the last day by default) the device experienced network-related issues. To achieve this, click on the icon at the right, top corner. Summary graphs plotted for a default period of 24 hours, will then appear.

You can override the default timeline of 24 hours of the summary graphs by following the steps given below:

Click the button at the top of the dashboard to invoke the Dashboard Settings window.
Select the Summary Graph option from the Default timeline for list.
Set a different default timeline by selecting an option from the Timeline list.
Finally, click the Update button.

Similarly, you can choose to analyze the past trends in network performance using the History tab page, instead of time-of-day variations or performance summaries, by clicking on the icon at the right, top corner. A trend graphs that capture the minimum and maximum values that pre-configured measures registered during the default period of 24 hours, will be revealed.

You can override the default timeline of 24 hours of the trend graphs by following the steps given below:

Click the button at the top of the dashboard to invoke the Dashboard Settings window.
Select the Trend Graph option from the Default timeline for list.
Set a different default timeline by selecting an option from the Timeline list.
Finally, click the Update button.

You can even expand the trend graph by clicking on it.

In the enlarged mode, you can even alter the Timeline and the dimension (2D / 3D) of trend graphs. By default, the trend graph plots the minimum and maximum values of a measure during the given timeline. In the enlarged mode, you can change the Graph type so that the average values or sum of trend values are plotted in the trend graphs instead.

Note:

In case of descriptor-based tests, the Summary and Trend graphs displayed in the History tab page typically plot the values for a single descriptor alone. To view the graph for another descriptor, pick a descriptor from the drop-down list made available above the corresponding summary/trend graph.

At any point in time, you can switch to the measure graphs by clicking on the button.

Typically, the History tab page displays measure, summary, and trend graphs for a default set of measures. If you want to add graphs for more measures to this tab page or remove one/more measures for which graphs pre-exist in this tab page, then, do the following:

Click the button at the top of the dashboard.
The Dashboard Settings window then appears. From the Module list, pick Network, choose Overview as the Sub-System, and then, select History Graph from the Add/Delete Measures for list.
The measures for which graphs pre-exist in the History tab page will be automatically displayed in the Existing Value(s) list. To delete a measure, and in effect, its corresponding graph as well, select the measure from the Existing Value(s) list, click the Delete button, and then click the Update button.
To add a new graph, first, pick the Test that reports the measure for which a graph is to be generated.
Next, select the Measure of interest.
Provide a Display name for the measure. Then, click the Add button to add the measure to the Existing Values(s) list. Finally, click the Update button.
This will add a new measure, summary, and trend graph for the chosen measure to the History tab page.

Note:

Network

If you want to strictly focus on the current and past issues related to the availability of the network connection to the device/server, and network latencies / packet losses experienced by the device/server, pick the Network option from the Subsystem list.

For a network device, this dashboard reveals the following:

With the help of the digital displays available, which report the current network latency values for the device, you can proactively determine network-level slowdowns (if any). While digital displays are available for a default set of measures, you can configure additional digital displays or remove any of the existing displays by following the steps discussed below:

Click on the button at the top of the dashboard.
To add a new measure, select Network from the Module list, pick Network as the Sub-system, and choose the Digital Graph option from the Add/Delete Measures for list.
Doing so will display all the measure for which digital graphs pre-exist in the Network sub-system dashboard in the Existing Value(s) list. You can remove any of the existing measures by selecting a measure from the Existing Value(s) list and clicking the Delete button.
From the list of network-related tests that populate the Test list, choose a test, and then select the measure for which a digital graph is to be displayed from the Measures list.
Povide a Display name for the measure, and then click the Add button. This will add the measure to the Existing Value(s) list.
Finally, click the Update button.

Note:

Below the digital graphs is the Details tab page. If the target network device experiences a high network latency, then, using the Routers by Hop Delay bar graph and table available in the Details tab page, you can view the hop-by-hop connectivity and delay, zero-in" on the exact hop at which the delay has occurred, probe into the root-cause of the delay, and resolve the issue, so as to optimize network performance. You can expand the bar graph by clicking on it.

The History tab page, on the other hand, displays measure graphs by default, which indicate the time-of-day variations in the availability and overall network health of the device during the last 24 hours. You can click on a graph to enlarge it and view it clearly. You can even click on Timeline to modify the graph timeline, and thus analyze network performance over a longer time period.

The default timeline (of 24 hours) can also be overridden using the procedure discussed below:

Click the button at the top of the dashboard to invoke the Dashboard Settings window.
Select the History Graph option from the Default timeline for list.
Set a different default timeline by selecting an option from the Timeline list.
Finally, click the Update button.

To view the percentage of time during the last 24 hours for which the network performance was affected by issues, click on the icon at the right, top corner.

You can override the default timeline of 24 hours of the summary graphs by following the steps given below:

Click the button at the top of the dashboard to invoke the Dashboard Settings window.
Select the Summary Graph option from the Default timeline for list.
Set a different default timeline by selecting an option from the Timeline list.
Finally, click the Update button.

Using the graphs, you can effectively perform service level audits and detect when and what type of network issues caused the agreed-upon service levels to be compromised.

Similarly, click on the icon at the right, top corner of the History tab page to view and analyze the past trends in network performance. By default, the trend graphs will pertain to the last 24 hours.

You can override the default timeline of 24 hours of the trend graphs by following the steps given below:

Click the button at the top of the dashboard to invoke the Dashboard Settings window.
Select the Trend Graph option from the Default timeline for list.
Set a different default timeline by selecting an option from the Timeline list.
Finally, click the Update button.

Using these trend graphs, you can determine when network performance peaked and when it hit rock bottom - this way, you can easily infer how network performance has varied during the last 24 hours, and thus receive a heads-up on potential network anomalies.

Besides the above, you can instantly change the timeline of the measure/summary/trend graphs in the History tab page by clicking on the Timeline link at the right, top corner of the tab page. To change the timeline of a single graph on the other hand, click on the graph to enlarge it. In the enlarged mode, you can even change the graph dimension (3D / 2D).

Also, an enlarged summary/trend graph allows you to alter the graph Duration - i.e., view the daily or weekly summary/trend information, instead of the default hourly data in the graphs.

Also, by default, the trend graphs in the History tab page plot the minimum and maximum values of a measure during the given timeline. In enlarged trend graphs, you can change the Graph type so that the average values or sum of trend values are plotted in the trend graphs instead.

Note:

At any point in time, you can switch to the measure graphs by clicking on the button.

Typically, the History tab page displays measure, summary, and trend graphs for a default set of measures. If you want to add graphs for more measures to this tab page or remove one/more measures for which graphs pre-exist in this tab page, then, do the following:

Click the button at the top of the dashboard.
The Dashboard Settings window then appears. From the Module list, pick Network, choose Network as the Sub-System, and then, select History Graph from the Add/Delete Measures for list.
The measures for which graphs pre-exist in the History tab page will be automatically displayed in the Existing Value(s) list. To delete a measure, and in effect, its corresponding graph as well, select the measure from the Existing Value(s) list, click the Delete button, and then click the Update button.
To add a new graph, first, pick the Test that reports the measure for which a graph is to be generated.
Next, select the Measure of interest.
Provide a Display name for the measure. Then, click the Add button to add the measure to the Existing Values(s) list. Finally, click the Update button.
This will add a new measure, summary, and trend graph for the chosen measure to the History tab page.

Note:

As stated earlier, the Network Subsystem Dashboard of a network device provides measure graphs that track the availability of the device over the network, network latencies, and packet loss experienced by the device during communication. For a server/application however, the same Network Subsystem Dashboard will additionally display the following:

Measure graphs tracking the incoming and outgoing traffic of the target server during the last 24 hours (by default); using these graphs, you can determine when during the last 24 hours the network activity to and from the server was very high.
A bar graph depicting the network delay experienced at every hop; using this bar graph, you can accurately isolate the hop at which maximum network latency has occurred.
A table depicting the hop-by-hop delay.

Tcp

To zoom into the health of the TCP connections to and from a server, select Tcp from the Subsystem list.

The digital displays, enable you to promptly detect sudden spikes/dips in the rate of incoming and outgoing TCP connections, and unexpected connection drops. This way, you can receive a fair idea of the current TCP connection load on the target host, and can assess how well it handles the load. Clicking on a digital display will lead you to the layer model of the related component, where you can view the exact layer, test, and measure that is being represented by the digital graph.

The digital graphs displayed correspond to a pre-configured set of TCP statistics. If need be, you can override this default setting by removing any of the digital graphs that pre-exist or adding digital graphs for new measures. For this purpose, do the following:

Click on the button at the top of the dashboard.
To add a new measure, select Network from the Module list, pick Tcp as the Sub-system, and choose the Digital Graph option from the Add/Delete Measures for list.
Doing so will display all the measure for which digital graphs pre-exist in the Tcp sub-system dashboard in the Existing Value(s) list. You can remove any of the existing measures by selecting a measure from the Existing Value(s) list and clicking the Delete button.
To add a new digital graph, first, from the list of Tcp-related tests that populate the Test list, choose a test, and then select the measure for which a digital graph is to be displayed from the Measures list.
Povide a Display name for the measure, and then click the Add button. This will add the measure to the Existing Value(s) list.
Finally, click the Update button.

Note:

For shifting from the present to the past and analyzing past TCP performance, use the History tab page. By default, this tab page displays measure graphs revealing the time-of-day variations in current TCP connections, dropped TCP connections, and incoming and outgoing TCP connections, during the last 24 hours (by default). Using these graphs, you can quickly figure out the following:

When during the last 24 hours was the TCP load on the target host unusually high? When was the load uncharacteristically low?
Is there any increase in the number of TCP connections that were dropped? Is this increase sudden or consistent? If the TCP connection drops have increased steadily during the last 24 hours, when did this pattern begin?

If required, you can change the default timeline (of 24 hours) of these measure graphs, by doing the following:

Click the button at the top of the dashboard to invoke the Dashboard Settings window.
Select the History Graph option from the Default timeline for list.
Set a different default timeline by selecting an option from the Timeline list.
Finally, click the Update button.

If you want to perform service level audits on the TCP connection handling ability of a target host, then, you can configure the History tab page to display summary graphs of the TCP-related metrics, instead of the default measure graphs. For this, just click on the icon at the right, top corner of the History tab page.

The summary graphs denote the percentage of time (during the last 24 hours) for which each TCP-related measure had been in an abnormal state. This way, problem-prone performance metrics can be isolated and the reasons for their poor performance can be investigated. The default timeline for the summary (i.e., 24 hours) can be overridden by following the steps given below:

Click the button at the top of the dashboard to invoke the Dashboard Settings window.
Select the Summary Graph option from the Default timeline for list.
Set a different default timeline by selecting an option from the Timeline list.
Finally, click the Update button.

Similarly, to study the past trends in TCP-related statistics and predict the future behavior of the target host, you can have the History tab page display trend graphs of the TCP-related metrics. For this, click on the icon.

Using the trend graphs, you can figure out when (during the last 24 hours) the overall TCP activity and connection drops had peaked on the target host and when it was abnormally low. In the case of trend graphs again, the default timeline of 24 hours can be overridden by following the steps below:

Click the button at the top of the dashboard to invoke the Dashboard Settings window.
Select the Trend Graph option from the Default timeline for list.
Set a different default timeline by selecting an option from the Timeline list.
Finally, click the Update button.

You can change the Timeline of the measure/summary/trend graphs on-the-fly by clicking on the Timeline link at the right, top corner of the History tab page. To change the timeline of a single graph on the other hand, click on that graph to enlarge it. In the enlarged mode, you can even change the graph dimension (3D / 2D).

Also, an enlarged summary/trend graph allows you to alter the graph Duration - i.e., view the daily or monthly summary/trend information, instead of the default hourly data in the graphs.

Moreover, by default, the trend graphs in the History tab page plot the minimum and maximum values of a measure during the given timeline. In enlarged trend graphs, you can change the Graph type so that the average values or sum of trend values are plotted in the trend graphs instead.

Note:

At any point in time, you can switch to the measure graphs by clicking on the button.

Typically, the History tab page displays measure, summary, and trend graphs for a default set of measures. If you want to add graphs for more measures to this tab page or remove one/more measures for which graphs pre-exist in this tab page, then, do the following:

Click the button at the top of the dashboard.
The Dashboard Settings window then appears. From the Module list, pick Network, choose Tcp as the Sub-System, and then, select History Graph from the Add/Delete Measures for list.
The measures for which graphs pre-exist in the History tab page will be automatically displayed in the Existing Value(s) list. To delete a measure, and in effect, its corresponding graph as well, select the measure from the Existing Value(s) list, click the Delete button, and then click the Update button.
To add a new graph, first, pick the Test that reports the measure for which a graph is to be generated.
Next, select the Measure of interest.
Provide a Display name for the measure. Then, click the Add button to add the measure to the Existing Values(s) list. Finally, click the Update button.
This will add a new measure, summary, and trend graph for the chosen measure to the History tab page.

Note:

The Tcp dashboard is available only for hosts/applications, and not for network devices.

Note:

NetworkInterfaces

If you want to focus only on the speed, bandwidth usage, and traffic handled by the network interfaces supported by a network device, pick the NetworkInterfaces option from the Subsystem list in your Network Dashboard.

Like the other sub-systems, the dashboard for the NetworkInterfaces sub-system too begins with dial graphs and digital displays. These dial and digital graphs are configured for a default set of measures - typically, these measures will be key indicators of the performance of network interfaces. If one/more of these measures are currently abnormal for a particular interface, then, these dial and digital graphs will give you a heads-up on the anomaly, and also indicate which network interface is experiencing the issue. On the other hand, if more than one network interface is experiencing performance issues or if all interfaces are operating normally, then the eG Enterprise system randomly picks a network interface and presents the default metrics extracted from that interface in the dial and digital format. If required, you can configure dial and digital displays for additional measures, or can even remove the graphs that pre-exist by deleting the corresponding measures; for this, follow the steps discussed hereunder:

Click on the icon at the top of the NetworkInterfaces Dashboard. In the Dashboard Settings window that appears, select Network from the Module list, and NetworkInterfaces from the Sub-System list.
To add measures for the dial graph, pick the Dial Graph option from the Add/Delete Measures for list. Upon selection of the Dial Graph option, the pre-configured measures for the dial graph will appear in the Existing Value(s) list. Similarly, to add a measure to the digital display, pick the Digital Graph option from the Add/Delete Measures for list. In this case, the Existing Value(s) list box will display all those measures for which digital displays pre-exist.
Next, select the Test that reports the said measure, pick the measure of interest from the Measures list, provide a Display name for the measure, and click the Add button to add the chosen measure to the Existing Value(s) list. Note that while configuring measures for a dial graph the 'Measures' list will display only those measures that report percentage values.
If you want to delete one/more measures from the dial/digital graphs, then, as soon as you choose the Dial Graph or Digital Graph option from the Add/Delete Measures for list, pick any of the displayed measures from the Existing Value(s) list, and click the Delete button.
Finally, click the Update button to register the changes.

Note:

Let us now return to the dashboard. If you click on any dial/digital graph in the dashboard, you will be directly lead to the layer model page, which will display the exact measure represented by the dial/digital graph and the layer-test combination that reports the said measure.

The Comparison tab page below displays a series of bar charts depicting the top network interfaces in various performance areas. These bar charts enable you to quickly and accurately identify the following:

Which network interface is operating with the maximum speed?
Which network interface is consuming bandwidth excessively?
Which network interface is unavailable currently?
Which network interface is receiving data at a very high rate?
Which network interface is sending out data at a very high rate?

By default, these bar charts depict the top-10 network interfaces only. To view this graph clearly, click on the corresponding bar chart. Doing so enlarges the bar chart.

The enlarged bar chart too, by default, displays the TOP-10 network interfaces in the chosen performance area. For instance, if the Interfaces by Bandwidth usage chart is enlarged, then the magnified chart will display the TOP-10 network interfaces in terms of current bandwidth usage. Moreover, since these network interfaces are arranged in the descending order of the bandwidth usage, you can instantly identify the top bandwidth consumer. To view all the network interfaces supported by the device and the bandwidth usage of each, select ALL from the Show list. You can choose to view only a few of the top/poor players in a performance area, by picking a TOP-N or LAST-N option from the Show list.

Also, note that the bar chart displays only those network interfaces that are currently supported by the device. However, sometimes, to investigate past issues, you might want to determine the top performers or the poor performers during a time period in the past. For this, click on Compare History. This will invoke a Timeline field, using which you can alter the Timeline of the enlarged bar chart.

To add more comparison graphs to the Comparison tab page or to remove existing graphs, do the following:

Click on the icon at the top of the NetworkInterfaces Dashboard. In the Dashboard Settings window that appears, select Network from the Module list, and NetworkInterfaces from the Sub-System list.
To add measures for the comparison graph, pick the Comparison Graph option from the Add/Delete Measures for list. Upon selection of this option, the pre-configured measures for comparison graphs will appear in the Existing Value(s) list.
Next, select the Test that reports the said measure, pick the measure of interest from the Measures list, provide a Display name for the measure, and click the Add button to add the chosen measure to the Existing Value(s) list.
If you want to delete one/more measures for which comparison graphs pre-exist in the dashboard, then, pick any of the displayed measures from the Existing Value(s) list, and click the Delete button.
Finally, click the Update button to register the changes.

This way, the Comparison tab page enables you to effectively compare the current performance of the network interfaces on the basis of various performance parameters, so that the erring interfaces are swiftly identified. While updates on the current state of the network interfaces can introduce you to operational errors that crept in suddenly, to identify potential anomalies, the knowledge of both current and past performance is essential. The History tab page, when clicked, provides a series of measure graphs (by default) that allow you to analyze the past performance of the network interfaces. By default, these graphs are plotted for a period of 24 hours. You can however change the timeline of the graphs on-the-fly by clicking on the Timeline link at the right, top corner of the History tab page.

If need be, you can even override the default timeline (of 24 hours) of these measure graphs, so that the next time you visit the History tab page, the historical graphs are plotted for that timeline. To achieve this, do the following:

Click the button at the top of the dashboard to invoke the Dashboard Settings window.
Select the History Graph option from the Default timeline for list.
Set a different default timeline by selecting an option from the Timeline list.
Finally, click the Update button.

Using these measure graphs, you can determine the following:

Were there consistent/intermittent breaks in the availability of any of the network interfaces during the specified time period?
Did data traffic to/from any network interface increase significantly during the designated period?
Were any irregularities noticed in load balancing across the network interfaces during the designated period?
Was bandwidth usage optimal during the specified period? Which network interface contributed to an increase in bandwidth usage?
Were all network interfaces operating in normal speed during the said period? Did any network interface experience significant slowdowns? If so, which one?

You can enlarge a measure graph by clicking on it, and thus view it more clearly.

Like the comparison graphs, the enlarged measure graphs also, by default, plot the values of the TOP-10 network interfaces supported by the device. Accordingly, the TOP-10 option is by default chosen from the Show list. To zoom into the performance of only a few of the top players / weak players in that performance area, pick a TOP-N or LAST-N option from the Show list.

Besides enabling you to identify the best/worst performers in a chosen performance arena, the enlarged graph also enables you to assess performance of network interfaces across broader time periods - for this, you will have to select a different Timeline for the enlarged graph. Similarly, you can also change the dimension (3D / 2D) of a graph in its enlarged mode.

Typically, the History tab page displays measure graphs for a default set of measures. If you want to add graphs for more measures to this tab page or remove one/more measures for which graphs pre-exist in this tab page, then, do the following:

Click the button at the top of the dashboard.
The Dashboard Settings window then appears. From the Module list, pick Network, choose NetworkInterfaces as the Sub-System, and then, select History Graph from the Add/Delete Measures for list.
The measures for which graphs pre-exist in the History tab page will be automatically displayed in the Existing Value(s) list. To delete a measure, and in effect, its corresponding graph as well, select the measure from the Existing Value(s) list, click the Delete button, and then click the Update button.
To add a new graph, first, pick the Test that reports the measure for which a graph is to be generated.
Next, select the Measure of interest.
Provide a Display name for the measure. Then, click the Add button to add the measure to the Existing Values(s) list. Finally, click the Update button.
This will add a new measure graph for the chosen measure to the History tab page.

Note:

Since trend and summary computations do not occur for NetworkInterfaces test by default, you cannot view trend and summary graphs for network interface-related measures.

Note:

WindowsInterfaces

To analyze the speed, bandwidth usage, and traffic handled by the network interfaces supported by a a target server/application over time, pick the WindowInterfaces option from the Subsystem list.

Using the dial graphs and digital displays available in this dashboard, you can receive quick updates on current anomalies pertaining to the network interfaces supported by the target Windows-based component. Besides knowing what went wrong, you will also be able to identify which network interface has been affected, with the help of the dial/digital graphs displayed here. Clicking on the dial/digital graph will lead you to the layer model of the target component, where you can identify the exact layer and test that reported the measure represented by graph clicked on.

Though the dashboard provides dial/digital graphs for a standard set of measures, you can, if required, configure such graphs for additional measures, or remove any of the dials/digital displays that pre-exist. For this purpose, do the following:

Click on the icon at the top of the WindowsInterfaces Dashboard. In the Dashboard Settings window that appears, select Network from the Module list, and WindowInterfaces from the Sub-System list.
To add measures for the dial graph, pick the Dial Graph option from the Add/Delete Measures for list. Upon selection of the Dial Graph option, the pre-configured measures for the dial graph will appear in the Existing Value(s) list. Similarly, to add a measure to the digital display, pick the Digital Graph option from the Add/Delete Measures for list. In this case, the Existing Value(s) list box will display all those measures for which digital displays pre-exist.
Next, select the Test that reports the said measure, pick the measure of interest from the Measures list, provide a Display name for the measure, and click the Add button to add the chosen measure to the Existing Value(s) list. Note that while configuring measures for a dial graph the 'Measures' list will display only those measures that report percentage values.
If you want to delete one/more measures from the dial/digital graphs, then, as soon as you choose the Dial Graph or Digital Graph option from the Add/Delete Measures for list, pick any of the displayed measures from the Existing Value(s) list, and click the Delete button.
Finally, click the Update button to register the changes.

Note:

Below the dial/digital displays, you will find the Comparison tab page, which provides a default collection of comparison bar charts, each of which compares the performance of the network interfaces in a specific performing sphere. Using these graphs, you can not only isolate performance anomalies, but also identify those network interfaces that are contributing to such anomalies.

If required, you can configure the dashboard to display more comparison graphs than what is provided by default, or can even remove one/more comparison graphs that you feel are not very useful. For this, do the following:

Click on the icon at the top of the WindowsInterfaces Dashboard. In the Dashboard Settings window that appears, select Network from the Module list, and WindowInterfaces from the Sub-System list.
To add measures for the comparison graph, pick the Comparison Graph option from the Add/Delete Measures for list. Upon selection of this option, the pre-configured measures for comparison graphs will appear in the Existing Value(s) list.
Next, select the Test that reports the said measure, pick the measure of interest from the Measures list, provide a Display name for the measure, and click the Add button to add the chosen measure to the Existing Value(s) list.

If you want to delete one/more measures for which comparison graphs pre-exist in the dashboard, then, pick any of the displayed measures from the Existing Value(s) list, and click the Delete button.
Finally, click the Update button to register the changes.

Let us now refocus on the Comparison tab page. To view a comparison graph clearly, click on it; this will enlarge the graph.

By default, the enlarged comparison graph will reveal only the top-10 network interfaces in a specific performance area. You can, if need be, view all the network interfaces supported by the target component, or only a few best/worst players in a performance area, in the enlarged mode. For this, select the relevant option from the Show list.

To undertand how well the network interfaces of a component performed during some period in the past, and to nail that interface that may have been responsible for that problem during that time, simply click the Compare History link, and specify the Timeline for such a comparison.

For deeper insights into the historical performance of the network interfaces, use the History tab page. By default, the History tab page, displays measure graphs depicting the time-of-day variations in the performance of the network interfaces supported by the target host. By default, these measure graphs are plotted for the last 24 hours. To analyze performance over a wider time range, click the Timeline link at the right, top corner of the History tab page to change the graph timeline.

You can even override the default timeline (of 24 hours) of the historical measure graphs by following the steps given below:

Click the button at the top of the dashboard to invoke the Dashboard Settings window.
Select the History Graph option from the Default timeline for list.
Set a different default timeline by selecting an option from the Timeline list.
Finally, click the Update button.

You can enlarge a measure graph by clicking on it, and thus view it more clearly.

Like the comparison graphs, the enlarged measure graphs also, by default, plot the values of the TOP-10 network interfaces supported by the device. Accordingly, the TOP-10 option is by default chosen from the Show list. To zoom into the performance of only a few of the top players / weak players in that performance area, pick a TOP-N or LAST-N option from the Show list.

Besides enabling you to identify the best/worst performers in a chosen performance arena, the enlarged graph also enables you to assess performance of network interfaces across broader time periods - for this, you will have to select a different Timeline for the enlarged graph. Similarly, you can also change the dimension (3D / 2D) of a graph in its enlarged mode.

To view the percentage of time during the last 24 hours for which a network interface was affected by issues, click on the icon at the right, top corner.

You can override the default timeline of 24 hours of the summary graphs by following the steps given below:

Click the button at the top of the dashboard to invoke the Dashboard Settings window.
Select the Summary Graph option from the Default timeline for list.
Set a different default timeline by selecting an option from the Timeline list.
Finally, click the Update button.

Using the graphs, you can effectively perform service level audits and detect when and what type of network issues caused the agreed-upon service levels to be compromised.

Similarly, click on the icon at the right, top corner of the History tab page, to view and analyze the past trends in network interface performance. By default, the trend graphs will pertain to the last 24 hours.

You can override the default timeline of 24 hours of the trend graphs by following the steps given below:

Click the button at the top of the dashboard to invoke the Dashboard Settings window.
Select the Trend Graph option from the Default timeline for list.
Set a different default timeline by selecting an option from the Timeline list.
Finally, click the Update button.

Using these trend graphs, you can determine when the performance of network interfaces peaked and when it hit rock bottom - this way, you can easily infer how network interface health has varied during the last 24 hours, and thus receive a heads-up on potential interface-related anomalies.

Besides the above, you can instantly change the timeline of the measure/summary/trend graphs in the History tab page by clicking on the Timeline link at the right, top corner of the tab page. To change the timeline of a single graph on the other hand, click on the graph to enlarge it, and then proceed to change its timeline. In the enlarged mode, you can even change the graph dimension (3D / 2D).

Also, an enlarged summary/trend graph allows you to alter the graph Duration - i.e., view the daily or monthly summary/trend information, instead of the default hourly data in the graphs.

Moreover, by default, the trend graphs in the History tab page plot the minimum and maximum values of a measure during the given timeline. In enlarged trend graphs, you can change the Graph type so that the average values or sum of trend values are plotted in the trend graphs instead.

Note:

At any point in time, you can switch to the measure graphs by clicking on the button.

Typically, the History tab page displays measure graphs for a default set of measures. If you want to add graphs for more measures to this tab page or remove one/more measures for which graphs pre-exist in this tab page, then, do the following:

Click the button at the top of the dashboard.
The Dashboard Settings window then appears. From the Module list, pick Network, choose WindowInterfaces as the Sub-System, and then, select History Graph from the Add/Delete Measures for list.
The measures for which graphs pre-exist in the History tab page will be automatically displayed in the Existing Value(s) list. To delete a measure, and in effect, its corresponding graph as well, select the measure from the Existing Value(s) list, click the Delete button, and then click the Update button.
To add a new graph, first, pick the Test that reports the measure for which a graph is to be generated.

This will add a new measure graph for the chosen measure to the History tab page.

Note:

Uptime

To view the uptime details of a network device, you can select the Uptime option from the Subsystem list.

This dashboard reveals the following:

The Device Uptime section of the dashboard reveals the total time for which the network device has been up and running since it was last rebooted. The Uptime/DownTime Summary section provides a quick summary of the availability of the device during the last 24 hours (by default) - the details include: the total duration for which the device has been up and running in the last 24 hours, the percentage uptime, the total duration (in the last 24 hours) for which the device was down, the percentage of downtime, and number of reboots during the last hour. Using these details, you can determine whether the agreed uptime levels for the device were met or not, and if not, how much is the device falling short of its desired performance levels.

You can also infer whether the device experienced any reboots during the last 24 hours. To know more about each reboot, refer to the Reboot Summary section. For every reboot that occurred in the last 24 hours (by default), this section reveals when the device was shutdown, when the reboot occurred, and how long did the device remain down until it was rebooted. This clearly indicates the frequency of the reboots, and helps determine whether such reboots were scheduled or unexpected.

You can override the default timeline of the Uptime/DownTime Summary and the Reboot Summary, by following the steps discussed below:

Click the button at the top of the dashboard to invoke the Dashboard Settings window.
Select the Uptime/Downtime Summary option from the Default timeline for list.
Set a different default timeline by selecting an option from the Timeline list.
Finally, click the Update button.

Note:

Virtual Network

In order to provide in-depth insights into the network traffic handled by the virtual networks on a vSphere/ESX server, the Network Dashboard of such a server supports a specialized Virtual Network sub-system. The Virtual Network dashboard appears, when the Virtual Network option is chosen from the Subsystem list.

To the right of the Subsystem list in the Virtual Network dashboard, you will find a series of digital graphs displaying the current values for a pre-configured set of measures related to the traffic handled by the virtual networks. Network traffic congestions and the number of VMs affected by such a congestion can be instantly detected with the help of these default digital displays. This default measure list can be overridden by following the steps given below:

Click on the icon at the top of the Virtual Network Dashboard. In the Dashboard Settings window that appears, select Network from the Module list, and VirtualNetwork from the Sub-System list.
To add a measure to the digital display, pick the Digital Graph option from the Add/Delete Measures for list. In this case, the Existing Value(s) list box will display all those measures for which digital displays pre-exist.
Next, select the Test that reports the said measure, pick the measure of interest from the Measures list, provide a Display name for the measure, and click the Add button to add the chosen measure to the Existing Value(s) list.
If you want to delete one/more measures from the digital graphs, then, as soon as you choose the Digital Graph option from the Add/Delete Measures for list, pick any of the displayed measures from the Existing Value(s) list, and click the Delete button.
Finally, click the Update button to register the changes.

Note:

Clicking on a digital graph will lead you, where you can view the exact layer-test mapping that reported the measure represented by the digital graph clicked on.

Below the digital graphs, you will find the Comparison tab page. This tab page provides comparison bar graphs, which, by default, graphically compare the data and packet traffic handled by the vSwitches servicing the virtual networks. Using these default comparison graphs, you can accurately identify which vSwitches are experiencing heavy traffic. If need be, you can customize the Comparison tab page further by including measures of your choice for comparison, and/or deleting measures for which graphs pre-exist in the tab page. To achieve this, do the following:

Click on the icon at the top of the Virtual Network Dashboard. In the Dashboard Settings window that appears, select Network from the Module list, and VirtualNetwork from the Sub-System list.
To add measures for the comparison graph, pick the Comparison Graph option from the Add/Delete Measures for list. Upon selection of this option, the pre-configured measures for comparison graphs will appear in the Existing Value(s) list.
Next, select the Test that reports the said measure, pick the measure of interest from the Measures list, provide a Display name for the measure, and click the Add button to add the chosen measure to the Existing Value(s) list.
If you want to delete one/more measures for which comparison graphs pre-exist in the dashboard, then, pick any of the displayed measures from the Existing Value(s) list, and click the Delete button.
Finally, click the Update button to register the changes.

If a comparison graph appears to be very cluttered, then, you can view the graph clearly by clicking on it - this will enlarge the graph. In the enlarged mode, you can clearly view the top-10 (by default) virtual switches in a specific performance area, and thus identify that switch that has performed well/badly in that area. If need be, you can pick a different TOP-N or LAST-N option from the Show list in the enlarged mode so that, you can focus on the performance of more or a less number of vSwitches. Additionally, in the enlarged mode again, you can troubleshoot past issues in virtual networks by going back in time to view the top-n vSwitches during that time. For this, you will have to click on the Compare History link in the enlarged comparison graph, and provide a Timeline for comparison.

However, to perform a more elaborate historical analysis of the performance of virtual networks, you need to switch to the History tab page. This tab page displays a default set of measure graphs that track the variations in the traffic to/from each of the vSwitches during the last 24 hours (by default).

The default duration of 24 hours can be overridden by following the steps given below:

Click the button at the top of the dashboard to invoke the Dashboard Settings window.
Select the History Graph option from the Default timeline for list.
Set a different default timeline by selecting an option from the Timeline list.
Finally, click the Update button.

To instantly change the timeline of all the measure graphs at one shot so that, historical performance can be analyzed over a broader time window, click on the Timeline link at the right, top corner of the tab page. On the other hand, if you want to alter the timeline of a single graph alone, click on the graph; this will enlarge the graph.

Besides the timeline, you can even change the dimension of the graph (3D / 2D) in the enlarged mode. Also, by default, every measure graph will plot the values for the top-10 vSwitches on a vSphere/ESX server. If required, you can choose to view the historical performance of a more or a less number of vSwitches in the graph, by picking a different TOP-N or LAST-N option from the Show list in the enlarged mode.

Instead of the time-of-day variations, if you prefer to view a quick summary of virtual network performance across vSwitches so that, service level slippages are brought to light, click on the icon at the right, top corner of the History tab page. Summary graphs revealing the service level achievements of the pre-configured measures during the last 24 hours (by default), will then appear.

The default duration (of 24 hours) of summary graphs can be overridden using the following procedure:

Click the button at the top of the dashboard to invoke the Dashboard Settings window.
Select the Summary Graph option from the Default timeline for list.
Set a different default timeline by selecting an option from the Timeline list.
Finally, click the Update button.

To instantly change the timeline of all the summary graphs at one shot, click on the Timeline link at the right, top corner of the tab page. On the other hand, if you want to alter the timeline of a single graph alone, click on the graph; this will enlarge the graph.

Besides the timeline, you can even change the dimension of the graph (3D / 2D) in the enlarged mode. Also, an enlarged summary graph allows you to alter the graph Duration - i.e., view the daily or monthly summary information, instead of the default hourly data.

For analyzing past trends in virtual network performance, understanding traffic patterns, and isolating bottlenecks to smooth transmission, click on the icon at the right, top corner of the tab page. Doing so will invoke a series of trend graphs for pre-configured measures, which are plotted for a default duration of 24 hours. This duration can be overridden using the steps discussed below:

Click the button at the top of the dashboard to invoke the Dashboard Settings window.
Select the Trend Graph option from the Default timeline for list.
Set a different default timeline by selecting an option from the Timeline list.
Finally, click the Update button.

To instantly change the timeline of all the trend graphs at one shot, click on the Timeline link at the right, top corner of the tab page. On the other hand, if you want to alter the timeline of a single graph alone, click on the graph; this will enlarge the graph.

Besides the timeline, you can even change the dimension of the graph (3D / 2D) in the enlarged mode. Also, an enlarged trend graph allows you to alter the graph Duration - i.e., view the daily or monthly trend information, instead of the default hourly data.

Moreover, by default, the trend graphs in the History tab page plot the minimum and maximum values of a measure during the given timeline. In enlarged trend graphs, you can change the Graph type so that the average values or sum of trend values are plotted in the trend graphs instead.

Note:

At any point in time, you can switch to the measure graphs by clicking on the button.

Typically, the History tab page displays measure graphs for a default set of measures. If you want to add graphs for more measures to this tab page or remove one/more measures for which graphs pre-exist in this tab page, then, do the following:

To add a new graph, first, pick the Test that reports the measure for which a graph is to be generated.
Next, select the Measure of interest.
Provide a Display name for the measure. Then, click the Add button to add the measure to the Existing Values(s) list. Finally, click the Update button.
This will add a new measure graph for the chosen measure to the History tab page.

Note:

Hyper-V Network Adapters

While monitoring Hyper-V and Hyper-V VDI environments, the Network Dashboard comes embedded with two additional sub-systems, namely - Hyper-V Network Adapters and Hyper-V Switches.

The Hyper-V Network Adapters dashboard provides you with a quick look at the current and historical performance of the network adapters used by a Hyper-V host. Using this dashboard, you can be proactively alerted to real and potential irregularities in load-balancing across the adapters, and identify those adapters that may be experiencing unusually heavy load.

The dashboard begins with digital graphs for a default set of metrics, which indicate the data/packet load currently handled by the network adapters. The eG Enterprise system automatically compares the current value of a pre-configured metric across all adapters, picks the maximum value, and displays this high watermark in the digital format in the dashboard. A look at these digital graphs will hence instantly reveal whether any adapter is currently experiencing unhealthy load patterns. In the event of an abnormality, you can simply move your mouse pointer over the problem digital graph to know which network adapter is responsible for the anomaly. Alternatively, click on the digital graph, so that you can view the layer, test, descriptor (i.e., network adapter), and measure that has deviated from the norm.

If required, you can configure digital graphs for additional measures, or can even remove one/more digital graphs that pre-exist in the dashboard by removing their corresponding measures. To achieve this, do the following:

Click on the icon at the top of the Hyper-V Network Adapters Dashboard. In the Dashboard Settings window that appears, select Network from the Module list, and Hyper-V Network Adapters from the Sub-System list.
To add a measure to the digital display, pick the Digital Graph option from the Add/Delete Measures for list. In this case, the Existing Value(s) list box will display all those measures for which digital displays pre-exist.
Next, select the Test that reports the said measure, pick the measure of interest from the Measures list, provide a Display name for the measure, and click the Add button to add the chosen measure to the Existing Value(s) list.
If you want to delete one/more measures from the digital graphs, then, as soon as you choose the Digital Graph option from the Add/Delete Measures for list, pick any of the displayed measures from the Existing Value(s) list, and click the Delete button.
Finally, click the Update button to register the changes.

Note:

The Comparison tab page, as the name suggests, displays comparison bar charts for pre-configured measures. With the help of these bar charts, you can effortlessly determine on which network adapter load is abnormally high. To view a graph clearly, click on it.

In the enlarged mode too, by default, the graph will only reveal the top-10 network adapters in that performing sphere. You can choose a different TOP-N or LAST-N option from the Show list for viewing a few other best/worst performers.

If you want to know which adapter contributed to a network overload or an I/O bottleneck that occurred sometime in the past, use the Compare History link. Clicking on this link will allow you to specify a Timeline for comparison. Once specified, a comparison graph specific to that timeline will appear, revealing the top-10 network adapters during the specified time period.

You can, if required, customize the Comparison tab page by adding comparison bar charts for more measures related to network adapters, or by removing unnecessary graphs. For this purpose, do the following:

Click on the icon at the top of the Hyper-V Network Adapters Dashboard. In the Dashboard Settings window that appears, select Network from the Module list, and Hyper-V Network Adapters from the Sub-System list.
To add measures for the comparison graph, pick the Comparison Graph option from the Add/Delete Measures for list. Upon selection of this option, the pre-configured measures for comparison graphs will appear in the Existing Value(s) list.
Next, select the Test that reports the said measure, pick the measure of interest from the Measures list, provide a Display name for the measure, and click the Add button to add the chosen measure to the Existing Value(s) list.
If you want to delete one/more measures for which comparison graphs pre-exist in the dashboard, then, pick any of the displayed measures from the Existing Value(s) list, and click the Delete button.
Finally, click the Update button to register the changes.

For receiving greater visibility into the historical performance of the network adapters, use the History tab page. Clicking on this tab page will reveal measure graphs for a default set of load-related metrics, each of which will indicate how well the corresponding measure has performed across adapters during the last 24 hours (by default).

You can override the default timeline of 24 hours, by following the steps below:

Click the button at the top of the dashboard to invoke the Dashboard Settings window.
Select the History Graph option from the Default timeline for list.
Set a different default timeline by selecting an option from the Timeline list.
Finally, click the Update button.

In the event of an abnormality, you can use these historical measure graphs to ascertain whether the issue occurred suddenly or is only the climax of a consistent performance deterioration over time.

To view a measure graph clearly, click on it. The graph will then be enlarged.

You can change the Timeline of the graph in the enlarged mode, alter the graph dimension (3D / 2D), or pick a different TOP-N or LAST-N option from the Show list to view the historical performance of a few other best/worst network adapters.

To view the percentage of time during the last 24 hours for which a network adapter was affected by issues, click on the icon at the right, top corner.

You can override the default timeline of 24 hours of the summary graphs by following the steps given below:

Click the button at the top of the dashboard to invoke the Dashboard Settings window.
Select the Summary Graph option from the Default timeline for list.
Set a different default timeline by selecting an option from the Timeline list.
Finally, click the Update button.

Using the graphs, you can effectively perform service level audits and detect when and what type of network issues caused the agreed-upon service levels to be compromised.

Similarly, click on the icon at the right, top corner of the History tab page to view and analyze the past trends in network adapter performance. By default, the trend graphs will pertain to the last 24 hours.

You can override the default timeline of 24 hours of the trend graphs by following the steps given below:

Click the button at the top of the dashboard to invoke the Dashboard Settings window.
Select the Trend Graph option from the Default timeline for list.
Set a different default timeline by selecting an option from the Timeline list.
Finally, click the Update button.

You can click on a summary graph to enlarge it.

Using these trend graphs, you can determine when the performance of a network adapter peaked and when it hit rock bottom - this way, you can easily infer how a network adapters load patterns have varied during the last 24 hours, and thus receive a heads-up on potential adapter-related anomalies.

You can click on a trend graph to enlarge it. An enlarged summary/trend graph allows you to alter the graph Duration - i.e., view the daily or monthly summary/trend information, instead of the default hourly data in the graphs.

Moreover, by default, the trend graphs in the History tab page plot the minimum and maximum values of a measure during the given timeline. In enlarged trend graphs, you can change the Graph type so that the average values or sum of trend values are plotted in the trend graphs instead.

Note:

At any point in time, you can switch to the measure graphs by clicking on the button.

If need be, you can instantly change the timeline of the measure/summary/trend graphs in the History tab page by clicking on the Timeline link at the right, top corner of the tab page.

Typically, the History tab page displays measure graphs for a default set of measures. If you want to add graphs for more measures to this tab page or remove one/more measures for which graphs pre-exist in this tab page, then, do the following:

Click the button at the top of the dashboard.
The Dashboard Settings window then appears. From the Module list, pick Network, choose Hyper-V Network Adapters as the Sub-System, and then, select History Graph from the Add/Delete Measures for list.
The measures for which graphs pre-exist in the History tab page will be automatically displayed in the Existing Value(s) list. To delete a measure, and in effect, its corresponding graph as well, select the measure from the Existing Value(s) list, click the Delete button, and then click the Update button.
To add a new graph, first, pick the Test that reports the measure for which a graph is to be generated.
Next, select the Measure of interest.
Provide a Display name for the measure. Then, click the Add button to add the measure to the Existing Values(s) list. Finally, click the Update button.
This will add a new measure graph for the chosen measure to the History tab page.

Note:

Hyper-V Switches

Selecting the Hyper-v switches option from the Subsystem list will invoke a Hyper-v switches dashboard that serves as a single console from which you can observe the network traffic flowing into and out of the virtual switches associated with a Hyper-V server, identify abnormalities in traffic patterns, isolate virtual switches that are experiencing heavy network traffic, and review historical performance of the switches to ascertain whether such traffic-related anomalies occurred sporadically or regularly.

The dashboard begins with digital graphs for a default set of metrics, which indicate the data/packet traffic currently handled by the virtual switches. The eG Enterprise system automatically compares the current value of a pre-configured metric across all switches, picks the maximum value, and displays this high watermark in the digital format in the dashboard. A look at these digital graphs will hence instantly reveal whether any switch is currently experiencing unhealthy load patterns. In the event of an abnormality, you can simply move your mouse pointer over the problem digital graph to know which switch is responsible for the anomaly. Alternatively, click on the digital graph, so that you can view the layer, test, descriptor (i.e., virtual switch), and measure that has deviated from the norm.

Click on the icon at the top of the Hyper-V Switches Dashboard. In the Dashboard Settings window that appears, select Network from the Module list, and Hyper-V Switches from the Sub-System list.
To add a measure to the digital display, pick the Digital Graph option from the Add/Delete Measures for list. In this case, the Existing Value(s) list box will display all those measures for which digital displays pre-exist.
Next, select the Test that reports the said measure, pick the measure of interest from the Measures list, provide a Display name for the measure, and click the Add button to add the chosen measure to the Existing Value(s) list.
If you want to delete one/more measures from the digital graphs, then, as soon as you choose the Digital Graph option from the Add/Delete Measures for list, pick any of the displayed measures from the Existing Value(s) list, and click the Delete button.
Finally, click the Update button to register the changes.

The Comparison tab page, as the name suggests, displays comparison bar charts for pre-configured measures. With the help of these bar charts, you can effortlessly point to the virtual switch that is experiencing heavy traffic. To view a graph clearly, click on it. This will enlarge the graph. In the enlarged mode too, by default, the graph will only reveal the top-10 virtual switches in that performing sphere. You can choose a different TOP-N or LAST-N option from the Show list in the enlarged graph for viewing a few other best/worst performers.

If you want to know which switch contributed to a network overload that occurred sometime in the past, use the Compare History link in the enlarged graph.
