Observium and OpenVZ Disk Usage

PrincessOfCats

In observium, is there something I can configure to get storage to work with OpenVZ clients?

All my OpenVZ clients do not have the root filesystem disk space recorded.

All clients are running either ubuntu or debian with snmpd.

Fastest way is to make a plugin for Observium

You can use Munin plugins with Observium. The Munin plugin for OpenVZ can list per-VM stats.

I only have OpenVZ VPSes, but not OpenVZ nodes.

Thanks though.

I guess I will have to get a plugin for Observium.

Edit:

Smacks self in face

I already have collectd up and running for icinga, might as well take stats from there

Err, it's working for me....

observium by default should return the current disk space usage and total free on an OpenVZ system. If you want to view the disk usage of your Client's OpenVZ containers on your physical machine observium should do that by default also: http://i.imgur.com/ARql3jt.png

Only works on ploop

Seems to have some issues on simfs

I'm running simfs. Haven't changed anything about my configuration or something....

Looks like its snmp that's having some issues, while / is showing up in dskTable, its not showing up in hrStorageDescr

Edit: It's https://bugs.launchpad.net/ubuntu/+source/net-snmp/+bug/1403730

Submitted patch for now....
