[Nagiosplug-help] Monitoring SMART attributes for a changing set of disks.

[John Drescher]

For the last few years I have monitored 75 to 100 hard drives that are
in my linux based software raid servers using the check_smartmon.pl
plugin. I do this by having 1 service for each drive and SMART
attribute I want to monitor (currently temp and reallocated sectors).
However with drive failure and reconfiguring arrays after storage
upgrades this has been a little bit of a pain because after adding or
removing drives I need to go and manually update the nagios config on
the web server and on the raid server otherwise if I reduce or
increase the drives on the server I either get non monitored drives or
warnings in nagios. I was thinking I could make this a lot simpler by
writing a script on the client that runs at boot (or manually after I
make a change) and determines all of the drives in the system putting
the list into a text file. Then modify check_smartmon.pl to run on all
the drives listed in the script. Anyone do something like this or have
any thoughts about that?

Thanks,
John M. Drescher
