Options of Mounted Filesystems
|Distribution:||official part of Check_MK|
This check monitors the options with which a filesystem is mounted by
using the output of /proc/mounts. In normal operation mount options
should never change. In recent versions of Linux (e.g. UBUNTU oneiric),
the mount option commit= may change automatically depending
on the current battery state, so this option is being excluded from
the monitoring. Also excluded is the option localalloc= for recent
kernels and OCFS2 filesystems.
This check goes critical if the mount option ro appears. This
might indicate IO errors have occurred, causing the filesystem
to switch to read-only mode.
Any other change of mount options will trigger a warning state.
If the filesystem is not being found mounted, the check returns
an UNKNOWN state.
The mount point of the filesystem.
One service is created for each filesystem which is not of the type tmpfs.
The inventory uses the current mount options as check parameter.
Note: the agent sends only filesystems which have a device below
/dev, so network filesystems and virtual filesystems are excluded
by the agent.
