I'm surprised noone has pointed this out yet, but there is no problem. All you are monitoring off of this are deltas. If at time T the counter is -30000, and at time T' it's -29000,
-29000 - -30000 ======== 1000
So ops/sec are 1000 / (T' - T)
The deltas work just fine, regardless of whether the counter happens to be positive or negative.

Hello,
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?
Look:
[root@foo /root]# snmpget filer-e0.terra.com.br public .1.3.6.1.4.1.789.1.2.2.1.0 enterprises.789.1.2.2.1.0 = -1281161705
I know I can fix this by rebooting the filer. But I don't want to do that.
This is a F760 with Ontap 5.3.6.R2. It has a lot of traffic. ;-)
Does anyone here knows of a solution to this problem?
