A Guide to Monitor Linux Server using Prometheus and Grafana
3 years ago by majorswitcher to c/selfhosted
running a lemmy instance has learned me a lot about devops already!
I love playing around with this, the lemmy instance was a great reason. lemmyfly.org doesn't have a lot of traffic yet, I think it can handle some more. Currently running on 2 vcpu/4gb ram.
After chatting to my devops colleague at work I wanted to set up a Grafana dashboard with metrics on the server. Seems it's pretty pretty doable!
- I installed prometheus node_exporter on my lemmy server
- I created a second server at my VPS. Very cheap, and don't think I'll be running the Prometheus/Grafana 24/7 so I'll just create a snapshot of it, destroy the server and re-create when wanted
- Created an internal private network so the instances can communicate without exposing ports to the public
- Installed Prometheus on the new prometheus server
- Installed Grafana
- log in to Grafana, admin:admin then change password
- Go to the Grafana home dashboard, click on + sign and click on Import. In Import via grafana.com, put the dashboard id 1860 (preset for all prometheus node_exporter metrics) and click on Load.
- Done!

This would be nice to run on my home server to monitor my Lemmy instance in the cloud. It would also be nice to be able to check some Lemmy stats as well as general server stats. I'm not a grafana or Prometheus expert though.
