Network Node Interfaces tab

In order to ascertain how well the network is utilized in an environment and how well the Network Node routes the network traffic from/to specific applications, an exclusive Interfaces tab is necessary. This dashboard provides the administrators with in-depth insights to the overall performance of the net flow over the network and enables them to accurately isolate the root-cause of any network slowdown.

The Interfaces tab provides an all-round view of the health of the Network Node being monitored, and helps administrators pinpoint the problem areas by analyzing how well the traffic is handled by each Network Interface of the Network Node. Using this tab page therefore, you can determine the following quickly and easily:

  • Is the Network Interface currently available? If not, what could be the possible issue underlying the non availability?
  • How well the network traffic has been handled by each Network interface available in this Network Node? How problem-prone has the Network Node been during the last 24 hours? Is the Network layer been badly hit?
  • Has the administrative staff been able to resolve all past issues? On an average, how long do the administrative personnel take to resolve an issue?
  • Is the Network currently available?
  • How well the bandwidth is utilized for each of the Network Interface?
  • How many packets of data were lost over the network while being transmitted?

The contents of the Interfaces tab have been elaborated on hereunder:

  1. This tab page begins with a dial graphs section that provides you with quick updates on the status of a pre-configured set of metrics such as Is the network interface available?, bandwidth used, Memory utilization etc and network related metrics such as Network availability of the Cisco Router.

  2. Clicking on a dial graph will lead you to the layer model page of the Network Node; this page will display the exact layer-test combination that reports the measure represented by the dial graph.

  3. The Top Interfaces section that follows next provides a series of graphs for the Bandwidth usage and the Network traffic flowing through the Top - 10 Network Interfaces of the Network Node. The time period for which the graph is to be displayed can be altered using the Timeline drop-down list. Using the button, each individual graph can be enlarged.

  4. Apart from viewing the graphical display of network flow through the Top - 10 Network Interfaces, you can also alternately view a data table for the Top - 10 Network interfaces by simply clicking on the icon that is available next to the Timeline drop-down list of the Interfaces tab of the Network Node. At any point of time, you can revert back to viewing the graphical display of the Top Interfaces section by simply clicking on the icon in the data table.

  5. By default, the Bandwidth used list i.e., the percentage utilization of the bandwidth available over a network link is sorted in the descending order of the usage. If need be, you can change the sort order so that the Interfaces are arranged in, say, the descending order of values displayed in the Data transmit rate column - this column displays the rate of data being transmitted from the network interface over a network link. To achieve this, simply click on the column heading Data transmit rate. Doing so tags the Data transmit rate label with a down arrow icon - this icon indicates that the Top Interfaces data table is currently sorted in the descending order of the data that is transmitted from each network interface. To change the sort order to ‘ascending’, all you need to do is just click again on the Data transmit rate label or the down arrow icon. Similarly, you can sort the table based on any column available in it.

  6. You can also view the Top Interfaces data table in an enlarged mode in the Interfaces tab. To achieve this, simply click on the button in the Top Interfaces data table. Upon doing so, the enlarged data table of the Top Interfaces will then appear.
