lun monitoring

[Russell Adams]

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 OS's you can
query disk statistics, or you may be able to get the data from the
backend storage, or perhaps an aggregate from the SAN switch.

I am not aware of any integrated solutions except those high dollar
packages sold by storage vendors (ala TPC).

Good luck.
