[mrtg] Re: snmp v2 problems

[Bryant Loftin]

Hello, I'm monitoring a cisco c3500xl ios 12.0(5.1)XP. It has one interface
running gigabit fibre that is running close to maximum. It appears that when
the counter is over 120K mrtg/rdd doesn't graph on the inbound side,
outbound still graphs. Counters never seem to go over 120 current but max
showes 122k. Is this a 64bit counter issue as related to SNMPv2 and
mrtg/rdd? I tried using the latest SNMP_Session.pm/BER.pm from
http://www.switch.ch/misc/leinen/snmp/perl without resolution.

Does anyone have something similar to this scenario working correctly?

thanks
Bjl

Hello,
What's the situation with SNMPv2 and fixes used and if this isn't just my
problem is it on the to be fixed list?

Here's my environment:
active state perl v.629
mrtg v2.9.17
win2k
the device is a cisco c3500xl ios 12.0(5.1)XP

Here's the old version cfgmaker line:

cfgmaker --output=d:\mrtg\out\switches\switch10.cfg --no-down --descint
--subdirs=SNMPNAME_HOSTNAME public at switchIP

... logs 100mb ports fine but my 1G fibre port wraps over 32bit counter.
Here's what I just changed:

cfgmaker --output=d:\mrtg\out\switches\switch10.cfg --no-down
--snmp-options=:::::2 --descint --subdirs=SNMPNAME_HOSTNAME public at switchIP

... mrtg logs nothing.

globals are:

Htmldir: d:\\inetmrtg\www\switches
Imagedir: d:\\inetmrtg\www\switches
Logdir: d:\\mrtg\logs\switcheslog
LogFormat: rrdtool
IconDir: \mrtg\images\
PathAdd: d:\\mrtg\rrdtool\bin
LibAdd: d:\\perl\site\lib
RunAsDaemon: yes

thanks
