MRTG error: not showing traffic

GavB · 01-30-2008, 07:41 AM

Hello,

I wonder if anyone can help. I've installed MRTG on CentOS and am having problems getting it to display traffic data - all other graphs (CPU/memory/load/open connections etc) are working with no problems.

When I run MRTG I get the following errors:

Code:

# /usr/bin/mrtg /etc/mrtg/mrtg.cfg
WARNING: Problem with External get '/usr/local/apache/htdocs/mrtg/core/system network eth0':
   Expected a Number for 'in' but got ''

WARNING: Problem with Externale get '/usr/local/apache/htdocs/mrtg/core/system network eth0':
   Expected a Number for 'out' but got ''

ERROR: Target[index][_IN_] ' $target->[0]{$mode} ' did not eval into defined data
ERROR: Target[index][_OUT_] ' $target->[0]{$mode} ' did not eval into defined data

For some reason it's just not getting the traffic stats, does anyone have an idea of what could be causing this?

Thanks in advance

Probably, he's looking for traffic stats on the wrong SID, if you are using snmp to gather gata, google to find the right one and then insert it in the mrtg.conf.
