HP UX vPars and Integrity VM v6 manual Collecting and viewing utilization data

7 Collecting and viewing utilization data

Certain VM Manager views include utilization meters (bar graphs) that display current utilization data for a resource. For example, the VM Host Virtual Machines tab includes several utilization meters for each virtual machine listed, as shown in Figure 61. Using VM 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 VM Manager with HP SMH, but you cannot click them to obtain a Capacity Advisor report.

Using VM Manager with HP Matrix Operating Environment, you can cause Capacity Advisor to collect and display historical utilization data for a VM Host or selected virtual machines.

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 VM Host and each virtual machine. For more information, see “System and software requirements” (page 13).

Using VM Manager through HP SMH, viewing utilization meter data specific to virtual machines 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 16). Meters for the VM Host and host resources are still available if the VM Host's WBEM Utilization Provider is running.

Using VM 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 VM Manager menu bar. This menu item is not available when using VM 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 106).

For information on Capacity Advisor, including prerequisites for using Capacity Advisor features, see the HP Capacity Advisor 7.0 User Guide.
