For a while now I’ve had Grafana hooked up to InfluxDB and Telegraf. Using Telegraf I setup pings to ips along my route to the larger internet, major dns providers, and several large internet sites. I measure response time and packet loss. It has allowed me to cut through the Comcast BS when diagnosing problems with them. I can tell them for sure that the problem is inside their network and is the X hop from my router.

I recently started setting up Grafana over on a different server and I’m using Prometheus instead to monitor more than just the other server I was monitoring. I haven’t yet set it up with that but it looks like something similar is possible with Prometheus based on the small amount of research I’ve done on it.
