Checking Xenserver Disks and Mount Points
Posted: Fri Aug 21, 2015 5:17 pm
Hi,
I recently moved over to a different plugin to check available disk space on Linux boxes via check_by_ssh. I have the check.disk.pl plugin installed on Xenserver machines. They would no longer allow me to run the standard Nagios check_disk plugin. I changed to the perl variant, which works fine with one exception. BTW - these are Citrix Xenserver hypervisor hosts, running v. 6.5 of Xenserevr (current version). I have over 200 servers running some version of Xenserver. As I said I just started to have this issue with the canned "check_disk" plugn when moving to Xenserver 6.5.
Regardless - the issue is the check_disk.pl plugin does not seem to discriminate between the local disks on the server and mount points. We use a lot of different mounts, often to filers or NFS ISO shares in the Xenserver network. Unfortunately the plugin is reporting/alerting on the mounts. This cannot be. The perl plugin does allow me to specifically exclude drives by name, but it would mean some significant scripting to grab mounted drives and differentiate.
Anyone either seen this or have an alternative? There is nothing wrong with the plugin - it is operating correctly. I am just fielding a lot of reports of mount points being too full, when they aren't at all.
Really appreciate the help!
