Nagios configuration for SAN monitoring

[Sonika Sachdeva]

Thanks very much All. Thanks Edgar.

Edgar,

I think that tool would be very helpful. I am planning to monitor the
traffic on 2 brocade switches (224 ports each / 7 blades each) So that would
put a lot of load on the server as you mentioned.

It would be quite helpful if you could forward that to me.

Thanks,
Sonika
