NiFi - MonitorMemory Reporting Task

[#1]

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

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:
