Bandwidth monitoring issues

[alexander.francuzik]

Hello,

I am experiencing trouble with my Nagios XI trial copy. A port (in this case an AP on a Cisco switch) is added through the Switch/Router wizard, and it shows up normally. However, when it starts checking it gives me the following message: "/var/lib/mrtg/<switchname>_299.rrd does not exist."

I am currently running Nagios XI 2012R2.3, and I have attached my system profile. I have also attempted to repair the permissions with this script (http://assets.nagios.com/downloads/nagi ... ios_XI.pdf), but it doesn't seem to have helped.

Are any rrd's being generated for that switch? Was the service renamed at any point? If so you will need to remove it and re-add it, though that it is a little more involved than that so let us know.

If that is not the case, are you seeing graphs for any other devices?

[alexander.francuzik]

The rrd aren't being generated at all. I added the ports through the XI Switch/Router wizard, so the service wasn't renamed at all.

If that is not the case, are you seeing graphs for any other devices?

This will decide what path we take for additional troubleshooting and can be a big time saver.

Yes, I'm able to see graphs for other devices through Host Graphs and Graphs Explorer.

Had you previously been monitoring ports on this device, removed and readded them? Also if you had been monitoring them and switched from port name to descriptions for services, that can effect this. If so we have documentation on removing previously added ports and services. Check out the bottom of this link. http://assets.nagios.com/downloads/nagi ... Router.pdf

I have been monitoring ports on that device. That's how I went through it: At first there was the initial device configuration with a gigabit port and VLAN being monitored for status and bandwidth. Now I wanted to add more devices to the monitoring, so I went through the wizard for the device, however did not choose the old ports, just the new ones, to be monitored. I've been using descriptions since the beginning and this was unchanged.

I will go through the instructions the link mentions later on and will report any results.
