HP Integrity Virtual Machines Manager 4.3 User 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 105) have been met.
• Utilization meters provided by VM Manager tabs. Table 12 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 117).
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.
