HP Capacity Advisor 7.2 User Guide

Working with Capacity Analysis
The Capacity Advisor Consolidation software does not work with Capacity Analysis. Systems with
this license are not included in the analysis performed by Capacity Analysis and do not appear
in analysis query results.
Importing data for use in Capacity Advisor
To import system utilization data, the system must be discovered by HP SIM.
For systems that you know are running HP Performance Agent (OVPA), you can verify discovery
by clicking “All Systems” or “All Servers” in the HP SIM left navigation bar.
If the system has not been discovered, you can add it manually. (From the top menu bar, select
Options→Discovery.... You must be a privileged administrator user or root to see this option.)
For help on adding a system manually, see the “Discovery and Identification” topic in the HP
Systems Insight Manager Help. After you add a system, verify that the system appears in “All
Systems” view.
For systems running HP Insight Control performance management (ICperf), select Optimize→Capacity
Planning→Import Capacity Advisor Data→List ICperf Systems... to see the list of discovered servers
running ICperf.
Once you verify that the system of interest has been discovered by Systems Insight Manager, you
can import system utilization data into Capacity Advisor.
IMPORTANT: Avoid importing ICperf or OVPA data that overlaps time intervals where agentless
data collection has already occurred. Mixing the two data sets can produce confusing reports,
because the agentless collector obtains more metrics than the ICperf or OVPA collectors, and the
imported data will overwrite only the metrics that both collectors obtain. This is primarily an issue
when the imported data has invalid data points and the agentless set does not.
Instead, determine if there are time periods where data was not collected using the agentless
method. Import data only for those time periods. Capacity Advisor will behave as though all the
data collected is one contiguous set, and reports will better reflect the actual resource usage. See
“Ascertaining the data collection availability for a set of servers” (page 45) for instructions.
From the Optimize menu — Import HP OVPA Data
Prerequisites
• You must be logged in to Matrix Operating Environment. See “Accessing Capacity Advisor”
(page 37).
• The system(s) must be discovered by Systems Insight Manager.
Procedure 7 Import HP OVPA data into Capacity Advisor
1. Click Optimize→Capacity Planning→Import Capacity Advisor Data→Import OVPA System
Data....
2. Select the target system(s).
The Verify Targets screen displays.
3. Verify the target system(s).
You have the opportunity to add or remove systems here. When done, click Next.
The Specify Parameters screen displays.
4. Specify the begin and end dates desired to define the extent of the collection to import.
For example:
[-b 20111101 -e 20111231]
If no date range is given, all data up to 30 days is imported.
