RFE: procps tools should support lxc

[Jens Elkner]

Container management/monitoring is currently a pain, because procps do not support container, i.e. there is no way to tell the tools to "filter" the output wrt. a certain zone or to add a column, which shows the zone name a process belongs to.

E.g. for what is needed:
{ps|pgrep|pkill|top} ... -z $myzone
# show zone name as well
{ps|top} -Z

You can use /proc/pid/ns and /proc/pid/cgroup to group results into
containers. One example shown today on the lxc-users mailing list is

ps -eo pidns,cgroup:50,pid,user,args --sort pidns

Seems like the work here is in procps. Marking as such.

[Jens Elkner (jelmd)]

Actually that's not the same at all, because $cgroup != $lxc_name . Your workaround is absolutely user UNfriendly, i.e. still hard to read and for casual users inconvinient, because one needs supply all that many format options ...

Anyway, I agree, that these utils should support such things out of the box, but 'til than, it remains a distribution thing.

Just thought I'd let you know that procps-ng-3.3.11 was released today.

Among several bug fixes, LXC support was added to top and ps.

The source ca be found at:

And a dist tarball is available at:

The project has a mailing list at:
