A Guide to Monitor Linux Server using Prometheus and Grafana
(geekflare.com)
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!

i'm now looking into logging more specific http request data. Maybe https://github.com/martin-helmich/prometheus-nginxlog-exporter?
I'm not looking into logging http traffic, but that seems like a popular option
http_response metrics are also up, using https://github.com/martin-helmich/prometheus-nginxlog-exporter
would be nice to see the numbers go up :)
