mrtg #2

[elovkoff]

I have mrtg running on RH8 box, the moment I install it, all graphs are shown in the kbs/sec on the main page, after day or so it changes to
Mb in the graphs...any idea why?

cfgmaker script explicitely states to use it in bits....(--global 'Options[_]: bits, growright' )


./cfgmaker --global 'WorkDir: /var/www/html/mrtg' \
--global 'IconDir: /mrtg/images/' \
--global 'Forks: 4' \
--global 'Options[_]: bits, growright' \
--global 'RunAsDaemon: Yes' \
--global 'LogDir: /usr/lib/mrtg2/logs' \
--noreversedns \
--output /etc/mrtg/mrtg.cfg \
--subdirs=HOSTNAME \

tor_mgmt@torfwb

I think I know why it happens but I'm still interested in how this can be prevented.....
I notice that there was u huge spike of activity on all 8 monitored interfaces - for an instant outgoing traffic went up to 40 Mb and since then display graphs show everything in Mb - my take on this is that the moment there is something that exceeds specific value the graps adjust to Mb....the question is how to make them go back.....
Or is it a problem with specific mrtg version - mrtg-2.9.17-8?
Thanks,.

Keep answering my own questions.... :-)
After much digging on the internet I've found some post in the mrtg-developers mailing list that discribes the same scenario and attributes it to the following:
"When box hosting mrtg is down and then brought back online it can show a spike of the traffic that has nothing to do with the real traffic patterns"
Looks like a bug in this case.......(my mrtg box was down for 2 hours)
