I am monitoring nfs ops/sec in a F760 filer using MRTG, but the value that I am getting from the last few days are in "negative". I believe it happened an overflow in the integer type used to hold this data, right?
Well, it's an INTEGER so it's allowed to be negative - the mistake made was in not making it a Counter, and there's little you can do except wait for NetApp to release new code that adds to the MIB and gives proper Counters.
(Well, you can modify your polling arrangements to specifically treat the number you get back from this area of the MIB as a +ve integer. I believe someone has done just this sort of modification for Cricket. Have a read of the Cricket mailing list archives, for the thread "[cricket-users] Negative SNMP counters (netapp)")
