Hi, I have a bunch of Raspberry Pies hosting all kinds of stuff and I want to have a monitoring solution for all of that. What would be your recommendations?
My goal is to be able to have an overview of CPU load, network load, CPU temp and to see what’s going on inside docker containers as I have everything dockerized. I’d like the solution to be open source. I want the solution to be web browser accessible and have nice load graphs with history. I don’t want to spend too much time setting it up.
All my Pies are running RaspberryOS, which is Debian based.
Standard solution would be grafana + Prometheus on one server and a node exporter running on each pi. You then register the node exporters in Prometheus and use that as a data source for grafana. There you build a dashboard showing whatever metrics you want. It can also show some information about the Docker socket, like number of running/stopped containers and such.
Add in alertmanager and hook it to slack. Get notified whenever containers or systems are misbehaving.
Thanks!
