Server resource utilization monitoring starts after you enable data collection and
continues until you disable it. Server utilization data is stored on the Hardware Management Console (HMC).
The number of servers that can be monitored is determined by the HMC. You can view the number of managed servers that can be
monitored by accessing the Performance and Capacity Monitor preferences REST
API at the following uniform resource identifier:
https://your_hmc_ip_address:12443/rest/api/pcm/preferences.
Follow these steps to enable data collection for one or more servers.
- Choose one of the following navigation options depending on the interface type of the Hardware Management Console (HMC):
- Specify the number of days for which you want to store
performance data by typing in a number in the range 1 - 366. Otherwise,
click the up or down arrows next to Number of days to store
performance data under Performance Data Storage.
Note: By default, the HMC is
set to store data for 180 days. The maximum number of days for which
it can store data is 366.
- Click the toggle switch in the Collection column, next to the name of
the server, for which you want to collect data. Otherwise, click All On to
enable data collection for all of the servers that the HMC manages.
Note: If you request to monitor a number of managed servers that exceed the maximum number of
managed servers that can be monitored by the HMC, the
HMC displays an error.
- Click OK to apply the changes and
close the window. The HMC Management topic
pane is displayed in the main window. You can now review the collected
data by accessing the Performance and Capacity Monitor home
page.
