800M overflow ?

[flopunctro]

Hi folks,
why are my traffic graphs "cut" at 800Mbit/s, like this http://neo.tm.ew.ro/poze/800M-overflow.png ?
Cacti doesn't complain anything about that host/DS in the logs, not even when I increase the verbosity.

I've dug a little on Google, and all I could find is this: http://osdir.com/ml/network.cacti.user/ ... 00032.html
but i'm figuring that's a 800M bug in the pgsql backend...

I'm using Cacti 0.8.6j on CentOS 4.5, installed and updated with yum (+rpmforge repo), and I have no other problems whatsoever. I've switched to cactid, as I'm polling 1000+ DS's.

This sounds very much like an error with rrdtool MAXIMUM settings for a datasource. Find more at the second link of my signature

Gandalf, you were right. Step 7 from your tutorial was very helpful; my .rrd files had a maximum, though I've modified the template and the DS's to have "0" maximum.

Thank you very much.
