HP Integrity Virtual Machines Manager 4.1 Software: User Guide

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 Vir tual Machines tab includes several utilization
meters for each virtual machine listed, as shown in Figure 7-1. Using VM Manager with Insight
Dynamics - VSE for Integrity, you can click a meter to view a more detailed historical data report
provided by HP Insight Capacity Advisor software. These meters are visible when using VM
Manager with HP SMH, but you cannot click them to obtain a Capacity Advisor report.
Figure 7-1 Utilization meters displayed by the VM Host Virtual Machines tab
Using VM Manager with Insight Dynamics, 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 Insight Dynamics - VSE for Integrity 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 Insight Dynamics, you can enable collection of utilization data from
systems licensed for HP Insight Capacity Advisor software. 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 HP SIM/Insight Dynamics 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 112).
For information on Capacity Advisor, including prerequisites for using Capacity Advisor features,
see the HP Insight Capacity Advisor 6.0 Software: User Guide.
