What would you monitor? Path availability would be the only item of note, and querying that information will vary by SAN driver and OS. Otherwise a LUN should show up as a disk with a filesystem that could be monitored with existing tools. On Tue, Feb 03, 2009 at 12:14:57AM +0800, Marc Ismael

Marc, In the spirit that each tool is supposed to fill one function and do it well, I don't use Nagios for trending. Nagios is operational status monitoring only. I'd suggest you look at other tools for that level of performance. One issue you will have is where will you query it? On certain
