Hello Team,
While configuring the Link balancer bandwidth monitoring in Nagios XI (5.8.1), Nagios is detecting 10 Mbps as "Max Speed". But, the actaul "Max Speed" value is 20 Mbps.
Could you please help us to understand how exactly it is fetching the "Max Speed" value?

Then open that file and run the command at the top (but add
2> /tmp/OUTPUT.txt onto the end of it) and then PM me
/tmp/OUTPUT.txt after the command finishes. For example:

That output isn't proper, I don't think you ran the proper command. Please PM me this file so I can construct it for you:
- Change X.X.X.X to the IP of the device you are having issues with
Code: Select all
/usr/local/nagiosxi/tmp/mrtg-X.X.X.X

What is the output of this command?
- Change yoursnmpcommunity and X.X.X.X to the IP of the device showing 10 that should show 20
Code: Select all

Your remote device is reporting it as 10, this would be an issue with the remote device as we are only returning what the remote device is serving. You'll need to reach out to your vendor of that device and ask them why that is and if there is anything you can do in the remote devices settings in order to have it output 20.
