Unix & Linux Stack Exchange is a question and answer site for users of Linux, FreeBSD and other Un*x-like operating systems.. It's 100% free, no registration required.

I'm looking for some reference documentation to explain what each of the settings are, for each control group.

For example, there's cpuset.cpus, I think setting this to 0 means use all CPUs, setting it to 1 limits you to 1 core. And cpuset.shares, how is that configured exactly?

Surely there's a reference doc that simply explains each of the settings somewhere right? Anyone have a link?

cgroups is still quite in flux in the Linux kernel. Probably the best documentation is LWN's coverage, perhaps H-online or Kernelnewbies have something to say. Currently systemd is the most prolific user.

A big thanks to Red Hat, I finally tracked down the reference documentation I was looking for in their documentation. I expect that there's no difference between Red Hat and other distros on this point.
