Subject Ways to monitor Virtual Router disk space
Date Fri, 20 Mar 2015 20:17:33 GMT
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?
