[mrtg] No Data (again)

[Steve Shipway]

What happens when you run MRTG to collect the data?

Either the data are not being gathered (scheduler or SNMP issue) or they cannot be stored (permissions issue)

1. Make sure you are actually runnning MRTG -- either as a daemon, or via cron every 5min.
2. Make sure the appropriate directories and files are writeable by the mrtg process
3. Run MRTG interactively as the normal user it runs as.  Is it producing any error messages that might clue you in to why the data are not being gathered?

Hi people!
First of all thank you so much for taking your time to read this and see if
you can spot anything that causes my troubles. I have searching a little on
the forum and I did not find anyone having similar trobles.

I have MRTG running on a 5.5 final CentOS Linux. Pages and graphs are
generated correctly but apparently the traffic is not monitored for some
reasons.

Anyone got any clues? Please excuse my ignorance in advance.
Thanks,
Andrea
