Monitoring and comparing multiple clusters
You can open the Performance Monitor or Adaptive Optimization for an individual cluster in a
separate window. Use multiple windows to monitor and compare multiple clusters at the same
time.
1. From the Performance Monitor or Adaptive Optimization window, right-click anywhere, and
select Open in Window.
The Performance Monitor Tasks menu is available in the window.
2. Click Close when you are finished.
Changing the sample interval and time zone
Set the sample interval to any value between 5 seconds and 60 minutes, in increments of either
seconds or minutes.
The time zone comes from the local computer where you are running the CMC.
Change the sample interval in the following ways:
•
Using the toolbar
•
In the Edit Monitoring Interval window, where you can also change the time zone
To change the sample interval from the toolbar:
1. In the navigation window, log in to the management group.
2. Select the Performance Monitor or Adaptive Optimization node for the cluster you want.
3. In the toolbar, change the Sample Interval value.
4. In the toolbar, select the Sample Interval Units you want.
