Options of Mounted Filesystems
Distribution offizieller Teil von Check_MK
Lizenz GPL
Unterstützte Agenten Linux

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.
