Do the memory heap dumps that get generated automatically when the JVM triggers an out of memory alert start a second heap capture specifically for Dynatrace? Do they capture the information from the heap dump that Websphere generates?
If you can make do with just the WebSphere dump, it would make sense to turn off the Dynatrace automatic memory dump (under Agent Mapping/Advanced) and just take manual memory dumps when needed, or turn it back on when needed for a specific ongoing issue.
hey, can anyone tell me if it is possible for the dynatrace dump to get cutoff before completing. I am think that websphere automatically restarts the jvm after OOM dump. The reason I ask is that the contents of the dynatrace dump do not match what is seen in the websphere dump. Also, the dynatrace dump is smaller than the heap.
