We're trying to standardize and reconfigure our dashboards. Over the years, we've configured certain measures which seem to not give what we actually need.
We're also seeing that there are many measures that seem to be similar to others, and it's difficult to tell which to use.
Could someone please suggest measures that will give proper data for each of the following:
I've found that the combination of 'Sun/Oracle Old Gen used' stacked with 'Sun/Oracle Survivor Space used' seems to be giving nearly the same as what we would see in gceasy for 'Heap After GC', with one exception - the Full GC spikes are not seen in either of these measures.
Is there a measure that exists or can be created to show the heap spike during full GC?
