In IIB documentation says:
'
The key indicators of a successful JVM heap setting are:
- GC overhead - the percentage of time spent in stop-the-world GC versus the time spent running the application
- GC pause times - the length of the stop-the-world GC cycles'
In the Resource statistics I can get
<resourceIdentifier name="Garbage Collection - J9 GC" CumulativeGCTimeInSeconds="0" CumulativeNumberOfGCCollections="32"/>
So IIB statistics do not give me the metrics I need 'percentage of time doing gc' and 'gc pause time'.
If the IIB jvm was a WebSphere Application Server (WAS) I could use jvm parameters to enable the verbose of gc and get a file with the gc statistics that I would format with a tool GCMV to get that values.
Since the IIB jvm is not a WAS, is it possible to get the same results, I mean enable verbose gc in IIB jvm?
