Viewing utilization data

Integrity Virtual Server Manager provides the following options for viewing utilization data. These
assume the prerequisites discussed in

“Enabling collection of utilization data” (page 117)

have been

met.

•

Utilization meters provided by Integrity Virtual Server Manager tabs.

Table 16

lists the meters

provided by Integrity Virtual Server 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 131)

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
VM or a vPar or a physical device on the VSP; if the meter is in a vPar box, the data is an
aggregate, registering the total throughput for all virtual devices on the vPar.
