The Resource Pools Tab Page

If resource pools have been configured on a virtual host, then the eG agent auto-discovers these pools and displays them as sub-nodes of a virtual host-node. The Resource Pools tab page appears only when a resource pool in the tree is clicked on. This tab page reveals the current configuration of the chosen resource pool, the General section indicates the Number of Virtual Machines on the Resource Pool, the Number of Running Virtual Machines, and the Number of Child Resource Pools. Besides the configuration, administrators can also use this tab page to determine the current state of each of the virtual machines and child resource pools under the chosen resource pool, and simultaneously indicates the resource usage by the pool in the Resources section.

• Below the b section you will find a Virtual Machine section. Clicking on a VM listed against the Virtual Machines section of a resource pool leads administrator directly to the layer model page of the virtual host on which that resource pool is configured, and automatically displays metrics that provide an “outside view” of that VM's performance. These metrics help administrators in understanding the impact the VM has on the physical resources of the virtual host.
• The Powered on VMs section displays the VMs that are currently powered On in the chosen resource pool, clicking on a VM against the Powered On VMs leads you to the layer model page of the virtual host on which that resource pool is configured.
• Similarly, clicking on a particular child resource pool displayed against the Child Resource Pools section, takes the administrator to the layer model page of the corresponding virtual host, thereby granting him a sneak peek at the resource usage metrics of that child resource pool, and enabling him to analyze how resource-intensive the child .
• Below the Powered On VMs list, you will find a Graph section. This section will be available in every tab page in the right panel of the VM dashboard. For the VMs tab, the Test list in this section will be populated with all those tests that report metrics for each VM on the virtual hosts of the chosen type. These tests will be sorted in the order of the test names, and the top test in the sorted test list will be selected by default in the Test list box. The Measures list naturally, will be populated with those metrics that the default Test reports. Since this list too is sorted in the order of the measure names, the top measure in the sorted list will be chosen by default in the Measures list. Accordingly, for the global Zones node in the left panel, the graph that appears in this section traces the variations in the default measure across all VMs (on virtual hosts of the chosen type) during the default timeline of 1 hour. Using this graph, administrators can compare the performance of a particular measure across VMs, and accurately identify those VMs that are weak in a chosen performance arena. If need be, you can plot a comparison graph for a different Test-Measure pair, for a different timeline. To change the timeline, click on the icon available in the Graph section. The Settings window will then pop out, allowing you to change the date and time.
• A legend is provided at the end of every graph clearly indicating which VM is represented using which color in the graph. This is accompanied by the Avg, Max, and Min values that the chosen Measure has recorded for every VM during the chosen Timeline. To view the legends above the graph, Check the Show Legends button in the Graph section.
