AW: check_disk best practices

[Helmut Januschka]

We are using a selfmade check disk plugin based on "df -h"
Run it with -h :))


So long

Betreff: [Nagios-users] check_disk best practices


I'm looking for advice on the best way to set up disk monitoring (linux specifically).  Every server I've been tasked to monitor is a little bit different in how it is partitioned, so rather than have a service for each partition and then keeping track of it all it makes sense to omit the -p and have it generically check all filesystems.  The problem is that the current stable check_disk does what looks like a "df -Pk" instead of a "df -Plk" so I'm picking up mounted filesystems in the output.

I'd like some tips and tricks from the rest of you on how you handle check_disk in your environments.

thanks in advance!
