Thanks for the massive assist in getting some basic SNMP checking working Teledata. I have fixed some bugs and have this check working again and ready to plug into Icinga.

I am a bit worried about the maths involved though and I am now working on rewriting this from scratch. None the less its a huge help.

Aaah, that was my first stab at the cluster size query.

I have a newer version that I created. It uses some counters that were introduced in later version of SAN/iQ. It is simplified, and takes much less time to run. (it no longer has to cycle through all the volumes) I think you have to be running 8.5 or newer (maybe 9, I can't remember). Anyway, here's the code:

I'm not the "forums police", but if you don't mind....

you can put the script in a .TXT file and attach it.
That retains its formatting and keeps the thread 'shorter' for reading the explanation.
Thanks.
