Monitoring IPv6 vs IPv4 traffic on Ubiquiti USG with SNMP

So. This has been painful. I decided I wanted to view how much traffic is flowing in and out of my USG now that I have IPv6!!!! It must be crazy, so let me go look. And then the painful truth, the USG controller has no visuals or commands to find the information. Bummer.

After a lot of web browsing, researching, additional hair loss, crying, and help, I have found the solution. I am going to turn on SNMP on the Ubiquiti USG, install telegraf, influxdb, and grafana on my Ubuntu 18.04 server.

This should be easy, right? No.
What could go wrong? A whole whole lot.

Setting up SNMP

I’m going to skip most the heartburn I had of trying to find the correct OIDs, getting the names correct, and ultimately realizing that Ubuntu does not load the MIBs in by default, so you have to do it by hand. Here’s what I did though:

# apt-get install snmp-mibs-downloader libsnmp-base libsnmp-dev snmp
# cd /usr/share/snmp/mibs
# wget http://dl.ubnt-ut.com/snmp/UBNT-MIB
# wget http://dl.ubnt-ut.com/snmp/UBNT-UniFi-MIB

Now, I did something bad, but since this is pretty limited, I loaded all of the MIBs in by default. My /etc/snmp/snmp.conf file looks like this:

# As the snmp packages come without MIB files due to license reasons, loading
# of MIBs is disabled by default. If you added the MIBs you can reenable
# loading them by commenting out the following line.
# mibs :
mibs +ALL
