We are getting the following errors in MRTG. How would we address this?

Most annoyingly comment out each port in the config file it is complaining about ... it's about 37 lines per port. Or simply delete the port from the config file.

The configuration files for MRTG are created with the program cfgmaker. While you may have selected to only monitor a handful of ports from your network device when using the wizard, MRTG will collect data from all the interfaces.

This is annoying. So if there is a device with 4 ports that I want to check, but the wizard finds 400, it will commit all 400 to configuration for MRTG to check? This could add a lot of unnecessary load to the XI box checking all the ports that aren't in XI.

I agree, I've entered it in a bug report for you with a link back to this thread:

Code: Select all

NEW TASK ID 6811 created - Nagios XI Bug Report: Only selected ports should be in the MRTG config file when using the wizard

Thanks ssax. This can be closed.
