read statistics in /proc/cgroups

[biello]

In some case, people may want to monitor statistics in /proc/cgroups on linux systems, I have already written some code for it.
will it be useful? if yes, I would like to contribute a pr. Thanks! @discordianfish

It depends on the details, but in general we support /proc/cgroups already: https://github.com/prometheus/procfs/blob/master/proc_cgroup.go

What do you have in mind?

[biello]

@discordianfish Current proc_cgroup.go reads /proc/[pid]/cgroup which describes infos for each process, not an overall view of control groups on the whole system. What I would like to read is the /proc/cgroups file, it contains relevant information.

https://man7.org/linux/man-pages/man7/cgroups.7.html has a clear description about this file.

Ah I see, yeah that seems reasonable to me!
