[lxc-users] We need a lxc-top utility

[István Király]

Hello CDR, ..

If your containers are accessible over ssh, you can iterate through the
containers and run a top or top-like command in each of them. You might
need unique users though.

 for C in $(lxc-ls)
 do
 ssh $C "top -n 1"
 sleep 1
 done

On the other hand, yes, it would be practical to see this directly on the
top of the host.
I think with a proper UID and GID mapping that should be possible somehow.

As long we do not have unprivileged containers, and GID / UID mappings, we
are still in development IMO.
