cgroup monitoring support tool

Hi all,

We are making some design choices based on the CPU % guarantees
provided by use of cgroups. I was wondering is a kernel patch or user
land tool exists to provide a meaningful representation of existing
CPU slices?

e.g. I have two cgroups in system with 1024 shares, I would expect
both of them running at 50% on an average. So I would like to know if
by running this 'utility' I get the list of cgroups in system with
their execution quantum in the last say 5 mins. I understand this
information can be extracted out from CPU accounting files from each
cgroup, but wanted to check if such patch/tool already exists before I
start writing one.

This will provide good debugging insight if a performance issues are
to be seen later.

Thanks in advance!
