Health of CIFS Mounts Mounted on UNIX/ Linux

Included in	All Checkmk editions
Source Code License	Open Source
Supported Agents	Linux AIX

This check probes the availability of CIFS mounts. The agent sends the status of all NFS mounts, if the command line utility waitmax is available (it is is used to avoid hanging if the server is not responding). The probe is done by trying a stat -f (system call statfs(2)) on the mount point. If that lasts longer then 2 seconds, then the server is considered to be not responding.

When you install the agent manually, please do not forget to also install waitmax into /usr/bin. That file is shipped together with the agent. When waitmax is missing, the agent will silently omit the section nfsmounts.

If the CIFS mount is "stale", then stat -f returns immediately but with a size of 0. The check detects that and results in a warning state.

To configure usage levels and whether or not to output metrics use the WATO rule "Network filesystem - overall status and usage (e.g. NFS)"

Item

The mount point.

Discovery

One service is created for each CIFS mount. This is doneby scanning /proc/mounts (linux) or using the mount command (aix). The file /etc/fstab is irrelevant.
