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 111) have been met.
• Utilization meters provided by VM Manager tabs. Table 7-1 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 127) .
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.
