Since I don't want to do it over again, I'll reference another post here: http://www.ee.ethz.ch/~slist/mrtg/msg22220.html [quote] You are probably encountering counter wrap issues. If you are polling 32-bit SNMP counters, the counter will hit its limit (2^32) and "wrap" back to 0 once every 5 minutes if the traffic on that interface is at 2^32/300=1,431,6558 octets (bytes) per second (109.22 Mbps). MRTG can handle a single wrap per polling interval. However, if you sustaining over 300 Mbps, the counter will wrap every 109.22 seconds. This is a limitation of the SNMP Counter, NOT MRTG. You have two options: Set your polling interval to poll more frequently and use RRDTool (MRTG with Rateup has a minimum of 5 minute polling interval so you must use RRDTool to poll more frequently) or use your device's 64-bit counters. Hopefully you can do the latter and your device has 64-bit counters as that would be an easy fix. With using a 64-bit counter, you won't have a wrap problem in a 5-minute polling interval unless you exceed 469,124,961,184 Mbps. :-) [/quote] If you need further information on counters, search the archive for "Counter-Wrap" and the mrtg-reference.html for "SNMPv2c".
