HP Matrix Operating Environment 7.3 Update 1 Release Notes

Capacity Advisor

Limitations

Capacity Advisor provides support for the HP ProLiant WS460c Gen8 workstation

Capacity Advisor is able to collect historical data from ProLiant WS460c Gen8 after

following the steps described in the How to license HP ProLiant WS460c Gen8 Blade

Workstations for Capacity Advisor White Paper located at Enterprise Information

Library.

Capacity Advisor does not support collecting data from KVM VMs

Capacity Advisor supports Linux servers, but does not support collecting data from KVM

VMs that are running on a Linux server. If a KVM host is added to HP SIM and licensed

to Matrix Operating Environment, then Capacity Advisor collects data from the KVM

host. In the Profile Viewer, the utilization data of a KVM host displays but there is not

a drop-down menu to see its VMs. In the Scenario Editor, a KVM host is displayed as

a hypervisor with no VMs so it appears as an idle host. A KVM host is not visible in

the Capacity Analysis Dashboard.

Capacity Advisor does not collect CPU utilization data from VSP 6.1 or 6.2 hosts

When using the Profile Viewer to view a Virtualization Services Platform (VSP) host,

the CPU data is not available. CPU data is only available for VSP VMs and vPars. In

the Scenario Editor, the only VSP systems available are VM hosts that are only hosting

VMs (See Table 1). In the Capacity Analysis dashboard the only VSP systems available

are VM guest and vPars.

VM guests are not individually available to the Scenario Editor. Adding a VSP Host to a Scenario Editor

will also add all VM guests that are hosted by the VSP Host.

Minor issues

Missing raw data for a time period

Capacity Analysis sometimes encounters missing data when it tries to compute statistics

for a day, week, or month. When no data is collected for a day, the average CPU

utilization for that day is stored as “unknown” and is displayed as a dash. If all of the

data has been collected for a day, the average can be computed and stored. However,

if data has been collected for only part of a day, then Capacity Analysis can report

the average of the data that was collected, or report that the average is unknown. In

this release of Capacity Analysis, the rules for displaying a dash or a value based on

partial data are not well defined and can vary from metric to metric.

Suggested action

If you have an analysis query that is sensitive to the amount of available data, you can

edit the query to add a filter expression for the “CPU % valid” (the CPU utilization

percentage). You might want to display the CPU % value in any query results to show
