This page is opened when the user clicks on a specific component in the topology graph, or a specific component in the COMPONENT LIST page. As per the model used by the eG Enterprise system, each component is represented as a set of hierarchical layers. The layers of a component are designed such that the state of a layer is impacted by the states of all the layers below it. The state of a layer is dependent on a set of measurements that map to the layer. The left side contains the hierarchical structure of these layers. Following conventional management practices, the eG Enterprise system displays states in red to indicate critical problems. Green is used to indicate good health, while blue is used to indicate an unknown state. Besides the above, orange is used to indicate major problems, and pink to indicate minor ones. The content on the right hand side of the page indicates the tests that map to a specific layer of the component-layer model on the left hand side of the page. Choosing a specific test results in the individual measurements of the test and their states being shown below. Some tests (eg. DiskSpace test, SystemDetails test) take descriptors, which are unique values using which eG indexes measures. For example, the different partitions on the disk form the descriptors of DiskSpace test. Clicking on a descriptor will display the measurements that are specific to that descriptor.

By default, when you click on a problem component in the eG monitoring console, you will be lead to this page, where you can directly view the problem layer, problem test, and problem measure. In other words, you will not have to click on a problem layer to view the problem test, and then click on the problem test to view the problem measure.

Note:

This default setting can be overridden so that, clicking on a problem component reveals only the layer model of that component, instead of revealing the problem layer, problem test, and problem measure. For this purpose, do the following:

• Login to the eG administrative interface.
• Follow the Configure -> Monitor Settings menu sequence.
• Click on the Other Settings sub-node under the General node in the tree-structure of the MONITOR SETTINGS page that appears.
• In the right panel, scroll down to view the When a problem component is clicked drop-down list. By default, the Go to problem measure option is chosen from this list. This indicates that by default, clicking on a problem component will directly lead you to the problem layer, test, and measure. To go to the layer model of that component instead, just pick the Go to layer model option from this list. Finally, click the Update button. Once this is done, then, everytime you click on a problem component, only the layer model of that component will appear. You will have to manually drill down from the problem layer to view the problem test and measure.

However, when you click on a component in the Normal state, then, this page will only display the layer model of the component. In this case, you will have to click on a layer to view its tests and then click on a test to view its measures. On the other hand, if a component in the Unknown state is clicked on, then, this page will display the layer and the test in the Unknown state, but will not display the measures.

Note:

By default, when you click on a particular layer in the monitoring model of a component, all the tests mapped to that layer, and all descriptors that have been enabled for the descriptor-based tests (if any), will be displayed in the Tests panel of the layer model page. Some tests support a large number of descriptors. For instance, the UserProfile test reports the profile size of each and every user to a Citrix or Terminal server. When such descriptors are displayed, they will naturally crowd the Tests panel. To enhance the 'look and feel' of the layer model page, you can switch off descriptor display by default. To ensure this, set the Show all descriptors for component by default flag in the MONITOR SETTINGS page of the eG administrative interface (Configure -> Manager Settings menu)to No.

If a test has a very large number of descriptors, then a link Click here for more information appears in this page. To view the complete list of descriptors for the test, click on this link. If a test reports measurements for more than one descriptor, then the eG monitor interface allows you to instantly compare performance across descriptors, by clicking on the button that will accompany a descriptor-based test in the layer model page. Clicking on this button opens, using which you can pick and choose the parameters that need to be compared across descriptors.

If you have navigated to this page from a service topology view, then you can return to the service topology page by following the steps below:

• Since this page displays the layer model, tests and measurements of a particular component, the name of the component will be displayed at the left, top corner of the page. First, click on the right-arrow button next to the component name.
• Doing so invokes a small window that displays the external agent (if any) that is externally monitoring the component, and the name of the service with which the component is associated.
• Click on the service name displayed here to return to the service topology view.

If you are viewing the layer model of a managed VMware ESX server/Microsoft Virtual server in this page, then, you will find a VIRTUAL COMPONENTS link at the right top corner of the page. This VIRTUAL COMPONENTS link will also appear while viewing the layer model of any of the server applications that is executing on a virtual host. Clicking on this link displays a topology diagram, which depicts the state of the monitored virtual host and each of the server applications executing on the virtual machines configured on that host. The VIRTUAL COMPONENTS link is pre-fixed by a state indicator, which indicates whether/not the virtualized environment being monitored is currently experiencing a problem.

Note:

If the current monitor user is not authorized to monitor the virtual host, but is associated with one/more of the server applications executing on a managed virtual host, then, while viewing the layer model of any of these server applications, the VIRTUAL COMPONENTS link will not appear in this page.

If you click on the VIRTUAL SERVERS layer of a monitored VMware ESX/Microsoft Virtual server, then an additional SERVERS link will appear next to the VIRTUAL COMPONENTS link. Clicking on the SERVERS link will enable you to receive an instant update on the guest operating systems configured on the monitored virtual host, and the current state of each guest. Similarly, if you click on the VIRTUAL DESKTOP layer of a managed VMware VDI server, then a DESKTOPS link will appear at the right, top, corner of this page. Clicking on the DESKTOPS link will list the virtual desktops currently executing on the target VMware VDI server.

When you click on a test in this page, the measurements reported by that test will be displayed in the panel below. Note that the measurements shown below reflect the last valid measurement received by the eG manager. The GRAPH option beside each measurement enables the user to view the measurement graph. The HISTORY option can be used to view the problem history of that particular measure. The DETAILS button can be used to obtain information pertaining to the test. The HELP button enables the users to view the context sensitive help on the measurements reported by the test under consideration. If the detailed diagnostic capability of specific tests is enabled, then the DIAGNOSIS button also appears against specific measures related to that test. Clicking on this button will provide you with the detailed measures pertaining to that test.
