[Xymon] Disk not being reported

[Scot Kreienkamp]

David/Ralph,

The solution I finally settled on was very simple… for the xymon client user, the first location in the PATH environment variable is /usr/libexec/xymon-client.  So I put a script called df in that directory with the sudo df command in it.  Since it’s first in the path for the xymon user and not in anyone else’s path that fixes my problem for xymon while not affecting anyone else on the system.  It is also minimally invasive, easily repeatable on all my other systems via puppet, and requires no future maintenance as I’m not changing any files that can be overwritten later.

Thanks!

You could copy the df/inode fragments from the original client script and make up a script for root to run from cron every 5 minutes.  Drop the output into a file that the Xymon client can read and just alter the client script to cat the file content.  You won't need to give sudo to xymon for that.

Hi everyone,

I am having a problem with some of my disk reporting.  Postgres requires 700 permissions on its data directory, which in my case is also a mount.  That causes non-root users (xymon) to get a permission denied error when running checks like inode and df.  I can’t change the permissions on the directory or postgres won’t start so the only other options I can come up with are to make xymon run as root (not a good idea), or have it use sudo to run its disk tests somehow.  Anyone run into this before?  Any words of wisdom on if it’s possible to use sudo to run the df/inode tests in xymon?
