The report package contains .xml files to update Analysis Center with new report templates. You can use these templates to create reports. The report templates consist of the five categories of reports: Dashboards, Hosts, vCenter (formerly known as Virtual Center), VMs, and Virtualization Candidates.
Access the Dashboard reports from the Analysis Center Console Enterprise pane in the Reports menu. Select AppManager, click Dashboards, and expand the vCenter folder.
Access the Hosts, vCenter, and VMs reports from the Analysis Center Console Enterprise pane in the Reports menu. Select AppManager, click Application Specific, and expand the vCenter folder.
NOTE:You can migrate any older reports saved in the Virtual Center folder to the vCenter folder and delete the Virtual Center folder, if you want.
Access Datastore reports from the Analysis Center Console Enterprise pane in the Reports menu. Select AppManager, click Application Specific, then click vCenter, and expand the Datastores folder.

The Virtualization Candidates report folder provides report templates for helping you determine whether your system is a candidate for virtualization. Virtualization provides many benefits such as ease of recovery, simpler maintenance, and the ability to snapshot a virtual machine at various states and revert to a state if needed.
Each Virtualization Candidates report lets you evaluate your system against the following Key Performance Indicators (KPI):
Host Network Reads
Host Network Writes
Resource pool Memory Utilization (%)
Resource pool Memory Balloon
Resource pool Overall Processor Utilization
Each report returns a column for each KPI and another for candidate status, which is either “Yes - a good candidate” or “No - not a good candidate.”
Before running a Virtualization Candidates report, run the AppManager Knowledge Scripts that supply the data that you will select from the Metric context in Analysis Center. The scripts in the NT category of scripts (for monitoring the Windows operating system) can supply the data you need. The following Knowledge Scripts provide data for the corresponding metrics in the Virtualization Reports:
|
Knowledge Script |
Metric |
|---|---|
|
NT_CpuLoaded |
% Overall Processor Utilization |
|
NT_NetworkBusy |
% Network Utilization |
|
NT_LogicalDiskIO |
Logical Disk Reads/Second |
|
NT_LogicalDiskIO |
Logical Disk Writes/Second |
|
NT_TopMemoryProcs |
Top Processes Consuming Memory (KB) |
NOTE:Knowledge Scripts from proxy-based AppManager modules, such as AppManager for Network Devices and AppManager for SNMP, do not provide data that is meaningful from a virtualization candidate perspective. Ensure you run Knowledge Scripts from agent-based modules, modules in which the AppManager agent is installed directly on the computer being monitored.
