What I meant by tooling not being aware is that its hard to pinpoint what exactly is using that memory.

Best you can do is do dumps, verify, enable NMT, verify.

It gives me no value to know that my heap is 60m, but my RSS is 600mb while reserved is 40GB. Need more details and those are not always provided i.e. “Unknown” category in NMT details.

Best is that top, pmap and nmt are all showing completely different values for resident size :> and its not a unit issue.

Not dumped to the OS of course, but JMX does have metrics for a lot of the in use non heap storage like codegen, profiler, etc..
