I assume you mean the average availability of the individual component monitors?
Once you've selected your components (make sure you select, Component, not Application in your data source), you can see the % Availability metric:
The same concept applies at the application level, but app availability is a rollup of the lower components, so I find it better to target components directly.
Sorry for the late reply….. Been off part of this week.
I just tried again following what you said, and that is what I was doing in the first place. I keep getting No Data to be Displayed, or words along those lines…
