Thanks, Rainer, for your prompt reply. I've tried what you suggested, and
was pleased to learn that MRTG supports the 64 bit counters. However, I'm
still having a couple of problems:
Here is the my configuration:
#----- begin config ----#
Workdir: (some dir)
Target[10.1.7.120.18]: 18:public at 10.1.7.120:::::2
Title[10.1.7.120.18]: FRSW-1 (No hostname defined for IP address): POS5/0
#----- end config ----#
When I run mrtg with this config, I get the following error:
ott-devtest3:19> mrtg dpawsey.cfg
backoff (:2) must be a number >= 1.0 at SNMP_Session.pm line 117.
Can you help? Is there a newer version of mrtg that I need to install? (I
am running 2.8.12) Also, what should I set the maxbytes parameter to? When
I try to set maxbytes to a number that can handle 64 bit counters, I get an
error message, saying 'Maxbytes must be smaller than maxint', which is a 32
Thanks very much for your help,
