Gathering data for Capacity Advisor
Capacity Advisor works best when using generous amounts of data to generate reports and create
meaningful simulation scenarios and collection starts soon after this product is installed and
configured. Data collected by the Utilization Provider is kept on a managed system for 30 days.
The HP Capacity Advisor Data Collection Service updates the data store every five minutes. Any
data transferred to the database on the CMS is kept by default for four years. This time period can
be changed. (See Data retention period.)
To create a meaningful simulation scenario or to view the historical resource utilization of a
workload, you must collect data from representative systems or the systems for which you want to
monitor resource utilization.
Once you have collected the data, you can create simulation scenarios or experiment with different
configurations and workloads to evaluate your system capacities. You can use Capacity Advisor
to plan for the future.
