I got the following error while running jvm-mon. Not sure if there are logs I can inspect or not.

$ jvm-mon
TypeError: Cannot read property 'Id' of undefined

Hmm, appears to be this line: https://github.com/ajermakovics/jvm-mon/blob/4d9a4fe21bf5283f2341a58b1b983b4eea8f597d/src/dist/jvm-mon.js#L173-L174 where 'vm' ends up undefined.

Does this happen on startup or after some action?

This does not happen with all my java programs. Anyway, it happens as soon as I try to inspect a java process.

I'm facing with this error too in centos.

Unfortunately, I'm not able to reproduce this issue. Does it prevent you from monitoring all processes or just one?
