Nagios Support Forum

Hi,

I have configured a switch using wizard after configuring the switch, some of ports on Bandwidth showing rrd does not exist "unknown" status.

“/var/lib/mrtg/10.10.10.1_119.rrd does not exist"

Let me know if anything needs to checked on this.

Regards,
Raj.

This is normal behavior for about 10 minutes, until the rrd is created.

If you have run the wizard before on the same switch/router there are additional steps outline in this document

Hi Scottwilkerson,
I have tried below steps, however issue still persists. Let me know if you want me to check further on this. Thanks!!

1. Removed the mrtgscan scan file from the /usr/local/nagiosxi/tmp folder
2. Removed all traces of the previous switch configuration from the /etc/mrtg/mrtg.conf
3. Verified syntax of the mrtg.cfg file
4. Reran the Switch/Router Monitoring Wizard, but still getting the rrd does not exist.

Raj.

After re-running the wizard, if you look in your /etc/mrtg/mrtg.cfg can you see an item labeled? If not, then this particular port on the switch must not exist any longer

I couldnt find Target[10.10.10.1_119] bandwidth for this, however i can see the Port status shows OK. do you think its relating to port doesnt exist?
Its really making confuse??? Port status is fine only bandwidth shows unknown..where would be problem???

Regards,
Raj.

If that line isn't in the /etc/mrtg/mrtg.cfg the port isn't being monitored for bandwidth.

How many port switch or router is this?

Is the status that is OK for port 119?

There is no line for Target[10.10.10.1_119] and i can able to see the status for the 10.10.10.1_119 port, it shows STATUS OKAY. There are 166 ports over this. Some of ports unchecked while configuration.
We have also tried with the http://support.nagios.com/wiki/index.ph ... h_Problems, however still problem persists.
Refer this topic Problems with Host Performance Graphs and Bandwidth - http://support.nagios.com/forum/viewtop ... h&start=20
same this issue which im facing too..

We are using RHEL 5.0 Nagios XI R2011 R2.4

One more thing, after performing the steps i couldn't see the performance graphs for all of my switch/routers. Let me know whats the wrong over this???

Raj

This is strange, did port 119 show up in the list when you re-ran the wizard?

Yes, this ports exists and i have reconfigure it again. However, the results remains the same. Im getting "/var/lib/mrtg/10.10.10.1_119.rrd does not exist". Let me know if anything else needs to be checked further... thanks!!

I would like to have an update over this...
