Change Performance Monitoring Settings

The Performance and Capacity Monitor tool collects allocation and usage data for virtualized server resources. It displays data in the form of graphs and tables, which are viewable from the Performance and Capacity Monitor home page. The Performance and Capacity Monitor is available on the Hardware Management Console (HMC) Version 8, Release 1, or later.

The Performance and Capacity Monitor gathers data and provides capacity reporting and performance monitoring. This information can help you to determine the available capacity and whether your resources might be overextended or under used. In addition, your interpretation of the graphs and tables might be useful for capacity planning and troubleshooting. For more information about The Performance and Capacity Monitor tool, see Using the Performance and Capacity Monitor.

The Performance and Capacity Monitor captures data only from the servers for which you choose to enable data collection.

To enable data collection, do the following steps:

1. From the Hardware Management Console (HMC), click HMC Management.
2. In the navigation area, click Change Performance Monitor Settings .
3. Specify the number of days for which you want to store performance data by typing in a number 1 - 366. Alternatively, you can click the up or down arrows next to Number of days to store performance data under Performance Data Storage.
   Note: By default, the HMC stores data for 180 days. However, you can specify the maximum number of days that the HMC stores data to 366 days.
4. Click the toggle switch in the Collection column next to the name of the server for which you want to collect data. Alternatively, you can click All On to enable data collection for all of the servers in your environment that the HMC manages.
   Note: You might be prevented from collecting data from all of the servers in your environment because storage space is limited. The HMC prohibits you from enabling data collection from more servers when the HMC determines that it might run out of estimated storage space.
5. Click OK to apply the changes and close the window. You can now review the collected data when you access the Performance and Capacity Monitor home page.
