HP Capacity Advisor 7.2 User Guide

You may also have servers in mind where data collection has been accomplished using software
other than the Utilization Provider. This can be done by collecting data from licensed systems for
which Capacity Advisor has agentless data collection capability or by importing data collected
by other agents, such as HP Performance Agent (OVPA) or Insight Control performance management.
Data import functions or modifications for agentless collection from a Windows CMS are accessible
from multiple locations:
• The Configure and Optimize menus on the top menu bar
• The Matrix OE Visualization tab (Configure menu)
• The Matrix OE Planning tab
• Using capagentlesscfg, capovpaextract, or cappmpextract on the command line of operating
systems where these apply.(see “Command reference” (page 193))
TIP: For lists of all menu options for Capacity Advisor features, see “Menus & tabs” in
Capacity Advisor Help.
NOTE:
Licensing and data collection
Typically, servers from which data are collected are licensed for Capacity Advisor and Matrix OE.
However, it is possible that not all servers in a data center or network are licensed to run Matrix
OE. One way to gather data from these servers for use in scenarios is to install the Utilization
Provider using the Insight managed system setup wizard and license each server with the Capacity
Advisor Consolidation software. You can also license each server where which you intend to use
agentless data collection.
For general information about licensing systems, see the HP Matrix Operating Environment Getting
Started Guide . For discussion of using the Capacity Advisor Consolidation software to collect
data for a systems consolidation effort, see “Data collection and the HP Capacity Advisor
Consolidation software” (page 42).
NOTE:
Performance for a virtual machine is usually calculated using the performance index calculated for
its VM host. However, when a virtual machine is moved from one VM host to multiple other VM
hosts within a short period of time (between one data transfer and the next), as might occur when
simulating virtual machines within a cluster, performance is calculated using the ratio of the clock
speeds multiplied by the performance index of the current VM host.

Environment on CMS and managed nodes. Its purpose is to pick up data from various collectors
