Graph but no data from eth0

[pix]

OK, I give up. I can't solve this on my own. Beside searching I've followed http://docs.cacti.net/manual:087:4_help.2_debugging to the best of my knowledge but unfortunately still no dice. Problem is that I get no data from eth0 on a LAMP-box (debian5.0/0.8.7b). I get only nan's and zero's. The other graphs like mem, disk space, average load, processes etc. are fine and dandy.

Any type of assistance will be most appreciated.

Assuming the device in question is Host[1] DS[16]...

Cacti is collecting data fine. That leaves an issues with updating the rrd file. If you manually run the update command (i.e. /usr/bin/rrdtool update /var/lib/cacti/rra/localhost_traffic_in_16.rrd --template traffic_out:traffic_in 1239640804:4027275509:726889315), does it work correctly?

Thanks for looking into this. Running the command using a later timestamp than when it was last run by cron gives nothing at all back. It just takes it. Unfortunately the graph looks just as empty as before.

Code: Select all

pix@sunshine:~$ sudo /usr/bin/rrdtool update /var/lib/cacti/rra/localhost_traffic_in_16.rrd --template traffic_out:traffic_in 1239707304:4027275509:726889315

I'm open for suggestions

after manually running the rrdtool update command, do the fetch again and see if the numbers are still blank -- they should not.

From your log file, cacti is retrieving data properly, so it's just some issue around the rrd.
