Frederik,
It works now but the values I am getting is different from what by my
MRTG/Cacti is giving me.
The check_iftraffic.pl plugin gives me
Total RX Bytes: 1434.86 MB, Total TX Bytes: 2213.91 MB
Average Traffic: 3.66 kB/s (0.0%) in, 3.77 kB/s (0.0%) out
My MTRG gives me
inbound = 50
outbound = 75
Why is the plugin giving me a different value? I know the MRTG value is
correct because when I work the eth0 interface with snmp, it gives me the
same value as the MRTG.
Thanks or your help so far.
Regards,
Alex
