Linux – Limiting resource usage per user in Red Hat Linux

linuxredhatresource-management

I need to limit CPU, memory and network bandwidth usage for a bulk of processes on per-user basis. User is in fact just logic grouping for several daemon processes and not real humans. So different users has similar (but not necessarily identical) set of running processes.

Unfortunately, I'm not even experienced Linux user, so I have no idea how to get it. Could you point out possible ways to accomplish this?

Pluggable Authentication Modules (PAM) limits will allow you to apply many of these quota restrictions on a per login basis: http://www.kernel.org/pub/linux/libs/pam/Linux-PAM-html/sag-pam_limits.html and Linux Administrator's Guide

Just to add on the above question.

You could use iptables with user matching to color the packets like so:

iptables -t mangle -A OUTPUT -p tcp -m owner --uid-owner someuser -j MARK --set-mark 100

And then use 'tc' to limit on a per user basis.

SystemTap is what you are looking for. It won't be easy (but it won't be too hard either) but it will pay off.

SystemTap is the RH designated & supported tool for this type of data gathering. The rpm package name is systemtap. It's similar to Solaris' Dtrace.

And, no, it is not a vague question. But ... yes, looking at only the behavior of one process and ignoring the rest of the system might give you a vague answer.
