Nagios Support Forum

Added all devices with router/switch wizard and I get no performance graphs and the interfaces show bandwidth rrd files as not found.

[root@dfmco-mon1 ~]# ls -l /var/lib/mrtg

[root@dfmco-mon1 ~]# LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg
ERROR: could not find RRDs.pm. Use LibAdd: in mrtg.cfg to help mrtg find RRDs.pm

It takes anywhere from 10-15 minutes after first running the wizard for those RRDs to properly populate.

If you're still experiencing this issue, do you see all relevant IPs/Ports in /etc/mrtg/mrtg.cfg?

It has been a week.
[root@dfmco-mon1 ~]# cat /etc/mrtg/mrtg.cfg

The error in the GUI for ALL Bandwidth entries is similar to:
/var/lib/mrtg/10.200.1.174_4.rrd does not exist.

And If I look into that directory, there are no rrd files at all:

[root@dfmco-mon1 ~]# ls /var/lib/mrtg/
mrtg.lock mrtg.ok

do you have the following install?

It was not installed. It is installed now. Why was that not installed as a dependency from the Nagios package? I installed Nagios using your rpm repository.

What steps do I need to do now to fix the missing rrd files?

Thanks!

Actually, that is all it took. I see the bandwidth green now.

Thanks!

Excellent.

Glad it is resolved!
