Bandwidth utilization reports zero

I am troubleshooting the results of the router wizard checks.

On Bandwidth utilization this check prints the results of the .rrd file my question is what check writes to the .rrd ?

$USER1$/check_rrdtraf -f /var/lib/mrtg/$ARG1$ -w $ARG2$ -c $ARG3$ -l $ARG4$

I setup a couple of routers which are reporting back 0 mb as bandwidth utilization my assumption is that the snmp permissions on the router are disallowing the data back to the NAgios server ?

When using the switch / router wizard, it add MRTG configuration in /etc/mrtg/conf.d that is run every 5 minutes to gather bandwidth utilization

thanks looks like a permissions issue on the .cfg files in the conf.d directory

Note: User is still having issues.

Is other performance data working? Or just the bandwidth checks?
If you run the following command from the cli, what is the output?

Code: Select all

LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lock/mrtg/mrtg_l --confcache-file /var/lib/mrtg/mrtg.ok

This error only seems to pertain to the newly added routers all other look ok. When adding the new routers I chose snmp v 2 tab , but the other checks like latency changed to snmp 0 , I was able to manually changed those. Where would I change the snmp for these particular checks ?

looks like the files are in the conf.d directory ?

I'm pretty sure the answer is that it needs to be changed in every affected file in the conf.d directory for every port.

Each Port is defined with a Target line

Code: Select all

Target[192.168.1.1_1]: 1:[email protected]:::::2
In that example:
public is the snmp community
2 is the snmp version (thats the :::::2)
