cacti not updating outbound >800mbps

[congiman]

Hi there,
Hopefully someone has an easy answer for this.

cacti version: 0.86h *
rrdtool-1.2.11-3
php4-4.4.0-6

When outbound traffic on a link exceeds ~800mbit, cacti fails to update it
on the graph.

I added some extra debugging and it is actually getting the correct data,
but its not making it into the graph.

debugging info below.

I have encountered this problems (on the same interface with both
bits/sec and bytes/sec graphs.


* This data was tested with an unpatched 0.86h. I later updated to include all the patches.
The Problem persisted.
I cleared poller cache in both scenarios.

figured it out:
I changed the data template (interface - traffic) for "maximum value" (traffic_in and traffic_out) to be: 1000000000 it was previously 100000000.

I had to delete the grapha and data source for it but then it worked just fine. (I gather this is not the correct way)
(if anyone has suggestions about not having to do this for my other interfaces I'll take them).

You can delete the rrd files, which when they get recreated they will have the correct max. Otherwise, you can use the tune function of rrdtool to change the max value in all your rrd files.
