If you're using ParallelGC the choice of names are going to be:</P><UL><LI>PS Eden Space </LI><LI>PS Survivor Space </LI><LI>PS Old Gen </LI><LI>PS Perm Gen</LI></UL><P>For G1GC:</P><UL><LI>G1 Eden</LI><LI>G1 Survivor</LI><LI>G1 Old Gen</LI><LI>G1 Perm Gen</LI></UL><P>And there are others for other garbage collectors.</P><P>If you're unsure you can connect to a process using jconsole and look at java.lang -&gt; MemoryPool:</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="3032-jconsole-memory-pools.png" style="width: 1747px;"><img src="https://community.cloudera.com/t5/image/serverpage/image-id/21663iCE70F6FA69905AA0/image-size/medium?v=v2&amp;px=400" role="button" title="3032-jconsole-memory-pools.png" alt="3032-jconsole-memory-pools.png" /></span></P> Mon, 19 Aug 2019 08:07:30 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/NiFi-MonitorMemory-Reporting-Task/m-p/143071#M23701 jfrazee 2019-08-19T08:07:30Z
