system filesystems are logged within munin

Bug #175297 reported by Olaf Schumann on 2007-12-10
Affects Status Importance Assigned to Milestone
munin (Ubuntu)

Bug Description

Binary package hint: munin-node

The df and df_inode log the systems directorys like /proc, /sys, /var/run etc. on my Ubuntu Feisty system.
The problem are the "device" of the mountpoints. These are "tmpfs, proc, sysfs, udev etc. whereas munin only filters the "none" and "unknown".

A solution is to patch the call to the df program in the munin df and df_inode plugins. (two times per plugin)

df -T -P -l -x none -x unknown -x udf -x iso9660 -x romfs -x ramfs -x sysfs -x proc -x tmpfs -x usbfs -x devpts -x nsfd | sed 1d | grep .......

This fix was incomplete -- system filesystems are not excluded when the plugin is reporting its configuration, which results in such filesystems appearing with usage as 'nan' (not a number).

Attaching a patch to fix this.

Revised the patch to also exclude bind-mounted filesystems (which will always have the same df output as another local filesystem).

This bug seems to have come back in jaunty. I have a server munin that collects data from various client munin machines. This bug (nan for /var/lock /var/run, etc.) started showing up on my 9.04 box running munin-node.
