Health of CIFS Mounts mountet on UNIX/ Linux

Distribution: official part of Check_MK
License: GPL
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.

Please note, that though this check outputs the current usage of the remote filesystem, no levels can be defined for the used space and no performance data is output. Please do a check for used space directly on the CIFS server.

Item

The mount point.

Discovery

All CIFS mounts are found automatically. This is done by scanning /proc/mounts (linux) or using the mount command (aix). The file /etc/fstab is irrelevant.
