Memory (or what ever resource) used per Process Group

[gilles_tabary]

Hello.

I have a very simple question : what is my top Process Group memory consumers ?

Yet, I must be missing something very obvious because I find no way to do it. It is easy to do it at Process Group Instance level. But I fail to goup by Process Group. I cannot split any of these metric per dt.entity.process_group :

builtin:containers.memory.residentSetBytes
builtin:process.memory
builtin:tech.generic.mem.workingSetSize

Using :parents transformation does not help because parents is HOST, not PG.

Any one have a solution ?

P.S. : I have a ticket already : 01265028.

Had to fight my way through about 

builtin:process.memory

built-in-metrics#other-process-metrics : ❌ builtin:process.memory : ... This metric is collected only if the Process instance snapshot feature is turned on and triggered ... This metric does not exist 24/7. So... cannot be used.

So... basically my question is back to square one : how can I report PG memory consumption ? Any idea ? Someone ? 🙂
