ll /var/lib = drwxr-xr-x. 2 root root 4096 Oct 6 21:50 mrtg

ll /var/lib/mrtg = -rw-r--r-- 1 root root 105160 Oct 7 20:10 (ip_port).rrd

-rw-r--r--. 1 root root 0 Oct 7 20:10 mrtg.ok

Is it still saying rrd does not exist? If thats so then there is something screwy with the filenames. Otherwise, we'll have to check the SNMP method that MRTG is using the poll the switch router using snmpget.

It only shows that message for a few minutes, then the circle goes green but does not show the bandwidth in/out or graphs for that port.

Attached a snapshot image of the issue. Again, the port image is orange and I get the message that the .rrd does not exist. After a few minutes, they turn from orange to green but do not show Mb/s in or out and no graph data on the ports.

brian,

Can you run

rrdtool fetch /var/lib/mrtg/<name of rrd file> AVERAGE

Do this on several of the RRDs, and post the output.

Ran the command against 3 seperate RRDs

Ok guys, I'm gonna need you to try something. Can you edit the file /etc/cron.d/mrtg and put this on the end

--debug=time,base,snpo,log --logging /tmp/mrtg.log

So the entire line should look like this:

*/5 * * * * root 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 --debug=time,base,snpo,log --logging /tmp/mrtg.log

Then let it sit for a few minutes and check the logs. If you could bundle the logs and then them to email me at nscott@nagios.com. They contain senstive information so I suggest not posting them on the forums.

Hi,

done it, but I am not finding /tmp/mrtg.log file.

thx
