HP Integrity Virtual Server Manager 6.0 User Guide

8 Collecting and viewing utilization data
Certain Virtual Server Manager views include utilization meters (bar graphs) that display current
utilization data for a resource. For example, the VSP Virtual Servers tab includes several utilization
meters for each virtual partition and virtual machine listed, as shown in Figure 66. Using Virtual
Server Manager with Matrix Operating Environment for HP-UX, you can click a meter to view a
more detailed historical data report provided by HP Capacity Advisor. These meters are visible
when using Virtual Server Manager with HP SMH, but you cannot click them to obtain a Capacity
Advisor report.

Using Virtual Server Manager with HP Matrix Operating Environment, you can cause Capacity
Advisor to collect and display historical utilization data for a VSP or selected virtual partitions.
Enabling collection of utilization data
Utilization meters display utilization data retrieved by the WBEM Utilization Provider. WBEM
providers are included with Matrix Operating Environment for HP-UX and must be installed on the
VSP and each virtual partition. For more information, see “System and software requirements”
(page 11).
Using Virtual Server Manager through HP SMH, viewing utilization meter data specific to virtual
partitions requires certain WBEM credentials to be set. If such credentials are not set, the meters
are dimmed. For more information, see “Setting WBEM credentials in HP SMH” (page 13). Meters
for the VSP and host resources are still available if the VSP's WBEM Utilization Provider is running.
Using Virtual Server Manager with Matrix Operating Environment, you can enable collection of
utilization data from systems licensed for HP Capacity Advisor. Select the Tools→Collect Capacity
Advisor Data menu item from the Virtual Server Manager menu bar. This menu item is not available
when using Virtual Server Manager through HP SMH.
Data is collected by WBEM Utilization Provider software on the licensed systems and stored on
the Central Management Server. Data collection is done on individual systems. Results from stdout
and stderr are saved to the Systems Insight Manager/Matrix Operating Environment Tasks
Results log. Capacity Advisor uses the collected data to calculate the utilization of CPU and memory
on targeted systems. You can collect data for:
• All systems licensed to use Capacity Advisor
• Specific selected systems licensed to use Capacity Advisor
To view the collected data, use the View→Capacity Advisor Data... menu item, as described in
“Viewing utilization data” (page 114).
For information on Capacity Advisor, including prerequisites for using Capacity Advisor features,
see the HP Capacity Advisor 7.0 User Guide.
