Segment Dashboard
eG Enterprise can also be used to monitor components that are not associated with services. For monitoring components that are a part of the component topology configured, choose the Segments option shown from the Monitor module. This will result in the display of the different segments configured for the target infrastructure, and their respective states. Each segment will be accompanied by the IP/hostname and state of the segment components associated with that segment. Note: If you want all the component-types associated with a problem segment to be displayed (in the SEGMENT LIST) instead of the component names, then you will have to set the Display component types in segment/service list flag in the MONITOR SETTINGS page (Configure -> Monitor Settings menu sequence) in the eG administrative interface to Yes. By default, this is set to No. Note: By default, against each segment displayed in the SEGMENT LIST page, the top-10 Components included in that segment will be displayed. Typically, to identify the top-10 components, eG Enterprise automatically sorts all the components associated with a segment on the basis of their current state, arranges the sorted list in the alphabetical order of the component names, and picks the first 10 components of this list. If you want more number of components to be displayed against each segment, do the following:
If a large number of segments are displayed, you can search for a particular segment, by specifying the whole/part of the segment name in the Search text box, and clicking the right-arrow button adjacent to the text box. Doing so will reveal all segments with names that embed the specified search string. Click on the Associations button to view the state of all the fully configured segments in their environment, and the users to which each of them are assigned. Clicking on the ‘left arrow’ in this SEGMENT LIST page opens a left panel that consists of a tree-structure. Each fully-configured segment will appear as the ‘nodes’ of this tree - besides the segment name, these ‘nodes’ will also indicate the current state of the segment. To view the components that form part of a segment and the state of each of these components, expand the ‘node’ representing the segment of interest to you. The segment components, along with their current status indicators, will then be listed as the sub-nodes of the ‘segment node’. If you click on a ‘segment node’ in the tree, the right-panel will instantly change to display three tab pages, namely - Segments, Components, and Topology. By default, the Segments tab page will open as soon as a ‘segment node’ in the tree is clicked. Systems Tab Page For every component that is included in the segment, the Systems tab page displays the state of each component and the real-time values of key hardware/network/operating system-level measures that have been pre-configured for the components. With the help of this tab page, you can receive instant intimations of hardware failures, network latencies, and other host-level performance ills that the segment components are experiencing currently.
If required, you can add more measures to this list or delete one/more existing measures. For this, click on the To add a measure to the Systems tab page using the CONFIGURATION SETTINGS pop up window, do the following:

By default, the contents of the Systems tab page are sorted based on the state of the segment components listed therein. If more that one component exists in the same state, then the components of that state will be sorted in alphabetical order. If need be, you can change the sort order. For example, if you wish to sort the components listed in the Systems tab page in the descending order of the values of their Disk Usage, just click on the Disk Usage label. Doing so, tags the Disk Usage label with a down arrow icon - this icon indicates that the Systems tab page is currently sorted in the descending order of the total disk space used by each component. To change the sort order to ‘ascending’, all you need to do is just click again on the Disk Usage label or the down arrow icon. Similarly, you can sort the Systems tab page based on any column available in the table. Click on any segment component in the Systems tab page to view the layer model of that component. Components Tab Page If issues at the application-level are hindering segment performance, you can promptly isolate such issues and the segment components affected by them using the Components tab page. By default, in the Components tab page for a particular segment, you will find pre-configured applicaton-level metrics pulled out of that segment component which is currently experiencing problems of the highest priority. This is why, the component type to which such a component belongs is chosen by default from the Type list in the Components tab page. If need be, you can pick a different Type from this list to view the current state of all segment components of that type.
You can even override the default measure list for a component type by configuring additional application-level metrics to be displayed in the Components tab page or by removing one/more metrics that pre-exist. For this, click on the To add a measure to the Components tab page, do the following:

When multiple inter-related components that are part of a segment experience slowdowns, it is often a challenge for administrators to accurately diagnose the ‘source’ of the slowdown - this is because, the problem in one segment component can affect the performance of other segment components that are dependent on it. To enable administrators to easily understand the inter-relationships between the various components that form a segment, and to help them precisely locate the root-cause of problems with a segment, the segment dashboard provides the Topology tab page. Clicking on any of the listed segments from the ‘segment node’, will display the topology of that segment. You can also pick a segment from the Select a Segment list in the Topology tab page to view the topology of the chosen segment. The topology of a segment associated with a Component Group can also be depicted in the Topology tab page. Large enterprises often have load balanced groups of servers providing web, middleware, and database functionality. The servers in the group often perform the same functions and have the same set of dependencies on other infrastructure components. For a segment with tens of servers in a group, the segment topology representation can quickly get very cumbersome. To handle such environments, eG Enterprise allows administrators to define server groups that represent a collection of similar servers. By including a server group in a segment topology representation, administrators can indicate that all the servers in the group have the same set of dependencies on other parts of the infrastructure. Topology representation using server groups are compact and concise to represent, and simple to understand. Clicking on the GROUP representation in the Topology tab page will lead you to the GROUP LIST page, which displays all the components associated with the group and their current state. If there is an issue with the group, then the GROUP LIST page will reveal which component in the group is causing the problem.
Note: Note that this page also appears when a division on the Segments bar graph in the Monitor Home page is clicked. In this case, the page will display only those segments that correspond to the state represented by the division that was clicked on. |
