How to log server memory usage of participant whenever they join a meeting

There are 2 things I wish to gain from this question. 1. how do I obtain said information. 2. when should whatever function does 1. be place for this to happen after user joins?

I don’t think it’s possible to get that information. When a user joins a number of components are involved (Prosody, Jicofo, JVB) and each of them will be impacted differently.

out of curiousity where is the source code/compiled code located for Jicofo and JVB since i have always wondered where jicofo and jvb is located in the case i can do some additional logging
