Monitoring the Asus RT-AC68U with the Telegraf agent Grafana and InfluxDB
11 min readDec 4, 2020
After completing the installation of Influxdb and Grafana, I wanted to capture metrics from my ASUS RT-AC68U router. The first option I looked at was from this article. This author’s approach was to use telegraf as an SNMP collector and send metrics to InfluxDB. I’m familiar with SNMP and I liked that is was a pretty standard access mechanism for network gear. I found this thread on snbforums that included configuration for telegraf collecting from a similar router. I did some SNMP walks on the router and found some of the data I was looking for
