How to monitor JVM memory in Apache NiFi

Question

I am creating a memory monitoring reporting tasks in Apache NiFi, to monitory the JVM usage. But i don't know which memory pool is appropriate to monitor usage of JVM. Any suggestion will be appreciated.

Memory pools available:

Code Cache
Metaspace
Compressed Class Space
G1 Eden Space
G1 Survivor Space
G1 Old Gen

As per my knowledge G1 Eden Space, G1 Survivor Space and G1 Old Gen are younger generation memory pool, so these three used to monitor java heap space. correct me if i am wrong.

Instead of individually monitoring the separate memory pool, i need to monitor the complete JVM memory. — Suresh Ram, Jul 26 '17 at 08:35
What is *"complete JVM memory"*? Amount of reserved or committed virtual memory of a Java process? Check [this question](https://stackoverflow.com/questions/35186322/find-my-application-memory-foot-print-programmatically). — apangin, Jul 26 '17 at 09:58
