HP Integrity Virtual Machines Manager Version 4.0 Getting Started Guide

Meters for the VM Host and host resources are still available if the VM Host's WBEM Utilization
provider is running.
When using VM Manager with VSE Management Software, you can enable collection of utilization
data from systems licensed for HP Capacity Advisor. Select the Tools→Collect Capacity Ad visor
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 providers 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 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 69).
For information on Capacity Advisor, including prerequisites for using Capacity Advisor features,
see HP Capacity Advisor Version 4.1 User's Guide.
Viewing Utilization Data
VM Manager provides the following options for viewing utilization data. These assume the
prerequisites discussed in “Enabling Collection of Utilization Data” (page 68) have been met.
• Utilization meters provided by VM Manager tabs. Table 3-8 lists the meters provided by
VM Manager tabs. Utilization meters display current utilization data for the associated
resource. The utilization information is a 5-minute average that is calculated and updated
on 5-minute boundaries. If the utilization cannot be displayed, the utilization meter is
dimmed. A label next to the meter indicates the probable cause. For information about these
labels, see “Utilization Meter Status/Error Information” (page 92).
CPU and memory utilization are expressed as a percentage. Network and storage meters
display I/O data in terms of throughput (for example, megabytes per second). Storage meters
are labeled as “Disk I/O” but provide utilization data for any supported devices (DVDs and
tape devices as well as disks). If a network or storage I/O meter is in a device box on a
Network or Storage tab, the data is specific to the device, whether it is a virtual device in
a virtual machine or a physical device on the VM Host; if the meter is in a virtual machine
box, the data is an aggregate, registering the total throughput for all virtual devices on the
virtual machine.
