Java CPU utilization on a per-thread basis

[Yaroslav Klyukin]

Hello everybody.

Does anyone know how to get per-thread CPU utilization of a running java
process without any modifications to it and in command-line?
visualvm does it, but it's a GUI.
I am looking for a command-line tool which I can run from a script.
Something like "top" under linux, but which would show every java thread.
Any hints or leads will be appreciated.

Thank you.

There are some command line tools here, although I'm not sure any do
exactly what you're asking.

The Jconsole one does appear to have a plug-in for thread monitoring,
although it seems to be GUI based also. Still maybe there's a hint in
there for you.
