HP Matrix Operating Environment 7.3 Release Notes

Capacity Advisor

Limitations

Capacity Advisor provides partial support for the HP ProLiant WS460c Gen8 workstation

Capacity Advisor does not support the Customize system from hardware catalog feature for this

workstation. The system template will not be available in the Edit Scenario - Create System screen.

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 http://www.hp.com/go/insightmanagement/docs.

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 whether the results are full

or partial. Additionally, you can change the analysis interval to a time period where all of the data

is more likely to be available.
