[rtg] Traffic is wrapping

[Shaun]

I change to SNMP version 2 in my rtg.conf and changed all devices in routers
to 64bit, re-ran the target maker utility and restarted rtg.  This is what
I'm seeing now with a -v

 

[Polls = 12260] [DBInserts = 5640] [Wraps = 21] [OutOfRange = 43]

[No Resp = 0] [SNMP Errs = 0] [Slow = 0] [PollTime = 2.426s]

Next Poll: 10...9...8...7...6...5...4...3...2...1...

Just FYI, all of those errors are coming from the same device which is a
Cisco 3750G

Shaun,

Your counters wrap most definitely because you're polling 32bit counters in
5 minute intervals. You had it right with polling the 64bit counters but
what you're likely missing is that you need to poll with SNMP v2c in order
to read them. Make sure your SNMP_ver setting in rtg.conf is "2".

Good luck.

Today I just realized that traffic that's being monitored on interfaces
pushing more than 100mbit look to be wrapping.  The graphs show the
interface using 70mbit when in fact they are using more like 170mbit.  I'm
wondering what would be causing this.  The gear I'm polling is cisco
7206-VXR-NPE-G2's and I'm polling using 32bit snmp.  I tried to use 64bit
thinking this may be the problem but for some reason when I change to 64bit
I get errors about mib.   Anybody else experience this?
