Switch monitoring wizard no bandwidth data for ports

[ctmoney]

The file had these directives before I ran the switch wizard, but they appear to be overwritten by the switch wizard. I added these lines back to the config file and I am now getting bandwidth data. Bug in the switch wizard?

[slansing]

It's possible they were split, do you have multiple mrtg.cfg files? Possibly one named mrtg-main.cfg or something like that?

[ctmoney]

No, just one file in the /etc/mrtg folder. I did add a second switch with the same result. The wizard overwrites everything in the mrtg.cfg file to include the top entries listed below. If I add them back to the config file after the wizard runs, the errors go away and I get an "Ok" status for bandwidth.

The Bandwidth status is showing as "OK", but there is not any bandwidth data appearing in the monitor. All ports are saying "0 up" and "0 down". The monitor has been in place for over an hour and there is a considerable amount of traffic going over several ports.

I'd like to verify which version of the wizard you are actually using, Admin > Manage Config Wizards > Switch And Router Wizard. What is the version number here?

Also, can we see the full current output of one of your interfaces that is showing incorrect information in Nagios XI, we need you to grab a snippit of code between the lines starting in "Target[" and ending in "</div>" after that div you should see the next interface starting.

[ctmoney]

I am on Version 2.0 of the switch configuration wizard.

Here is the config for an interface in the mrtg.cfg file

### Interface 1 >> Descr: 'GigabitEthernet1/0/1' | Name: 'GigabitEthernet1/0/1' | Ip: '' | Eth: '30-78-32-30-66-64-66-31-39-66-34-33-66-62' ###

Thanks for your help!

Just to clarify - you followed the steps, outlined in this document, correct?

Have you tried re-running the wizard, and using the SNMP ver.1 (for testing purposes)?

Do you have any mrtg-related errors in the "/var/log/messages"?

[ctmoney]

I did not follow the steps in the referred to document, this is for adding a whole new switch not adding ports to an existing switch.
Nothing in "/var/log/messages" referring to any error with the switch or monitoring bandwidth.
I have not tried version 1 of the switch wizard. I will have to stand up a test nagiosxi machine in my dev environment and give that a shot. I will let you know what I find.

I did not follow the steps in the referred to document, this is for adding a whole new switch not adding ports to an existing switch.

Actually, this is not correct. Even if you are adding a couple of extra ports (because they were, for example, administratively down when you were running the wizard), you will still have to follow this document, and remove ALL of the old data for this switch... quoted from the doc:

When a switch or router is already being monitored by Nagios XI, but you need to add an additional service...

[ctmoney]

This is still all from a new install though. I have not added any additional ports, or re-ran the wizard for the switches. Each time has been for a new switch.
