I've had a few incidents where conntrack logging has filled the /var partition, and break provisioning of new VMs (unable to save password).
And this got me thinking that there must be a way to monitor VR disk space.. Some things to consider: - I'm using XenServer, so AFAIK the VR ssh is only available from the XS link-local network. - I'd prefer to not build my own systemvm templates, ie. I'd like to use them as is - The monitoring should eventually end up in Nagios My idea so far is to make a collectd script or similar, that uses the CloudStack API to fetch a list of routers and its XS host, connect to the VR through the right XS Host and then push the data to graphite or similar. Then use the check_graphite plugin in Nagios to monitor the disk space. Does anyone have any insight to this, experience with doing something similar or other inputs? -- Erik
