Separate loadavg for individual containers

[harvie]

LXCfs finaly has the per-container loadavg!

I wonder how long it will take to get to the Proxmox...

I can't believe my eyes. This "feature" made its way into upstream. Yes, loadavg is not a very useful metric, but still gives a vague idea of the real load and practically all end every monitoring framework probes on these values. I think it's going to get in fairly quickly as the Proxmox team maintains its own custom kernel with cherry-picked patches most of the time IIRC. It would be nice to hear an official statement, though.

But if your customer sees loadavg of 10 in empty fresh CT with almost no services running it doesn't look very good.

It's not part of the kernel. It's part of lxcfs, which is afaik in usefspace (via fuse). However i hope we'll get this soon.

Yeah, my bad, it's a separate package. And yes, my concern is also is that people seem to be infatuated with load values and make (mostly false) assumptions based on them.
