NiFi - MonitorMemory Reporting Task

What are the possible values for memory Pool property in MonitorMemory Reporting Task ? I couldn't find any documentation around possible values for these.

1 ACCEPTED SOLUTION

The memory pool names are specific to whatever garbage collector you're using with the JVM. If you're using ParallelGC the choice of names are going to be:

  • PS Eden Space
  • PS Survivor Space
  • PS Old Gen
  • PS Perm Gen

For G1GC:

  • G1 Eden
  • G1 Survivor
  • G1 Old Gen
  • G1 Perm Gen

And there are others for other garbage collectors.

If you're unsure you can connect to a process using jconsole and look at java.lang -> MemoryPool:
