Check IBM Storwize V7000 Unified / SONAS VFS Warnings

Project Notes

Samba logs slow VFS (filesystem) operations into each interface node's syslog. This script detects such messages and adds them up for all nodes.
The plugin produces Nagios performance data so it can be graphed.

Note that this script only evaluates the new syslog entries logged after the last check was run, and requires information on when that was (-l parameter). Such information is available in Nagios via the $LASTSERVICECHECK$ macro.

Refer to the Samba documentation for details on the VFS module:

The actual code is managed in the following GitHub rebository - please use the Issue Tracker to ask questions, report problems or request enhancements.

It is strongly recommended to create a dedicated privileged Storwize V7000 Unified / SONAS user to be used by this script. This eases problem determination, allows for proper audit tracing and helps avoiding undesired side-effects.

To create a privileged user 'nagios' with password 'secret' on Storwize V7000 Unified / SONAS, run the following command as the Nagios operating-system user (by default called 'nagios', too):

# ssh admin@[mgmt_ip_address] mkuser nagios -p secret -g Privileged
