Nagios XI Bandwidth Monitoring Issue

[sdeshpande]

Support,

We recently moved from using SNMP V2 to SNMP V3 on our switch stack. With this change we are no longer seeing Bandwidth usage. Can you please assist ?

The simplest way to fix the bandwidth monitoring after changing from SNMP2 to SNMP3 it to rerun the Network Switch / Router Wizard with the SNMP v3 credentials which will generate updated config files that are needed.
Before doing this, the old config files will have to be removed from the system.
Login as root to the server and run the following to clear out the temporary scan files the wizard stores on the system.

Code: Select all

rm /usr/local/nagiosxi/tmp/mrtgscan* -f

Then the configuration file for your device will have to be removed at well. They are stored in the following folder on the server and the file name begins with the IP Address of the device.

Code: Select all

/etc/mrtg/conf.d

After cleaning out the files, rerun the Wizard and see if they start to report bandwidth again after 15 minutes.

Did that resolve the issue? Are we okay to mark this as resolved and lock the topic?

[sdeshpande]

Yes it did. Bandwidth graphs are working again
