I recently set up an uptime system to keep track of mine, and others’ systems. The system uses Uptime Kuma, which you can find here: https://github.com/louislam/uptime-kuma
I currently have 2 systems running, one running on the same server as this website, and one on a dedicated server.
I monitor all the servers I am currently using and have configured notification if something happens to my systems.
Dedicated Server: A local server monitoring everything from Server 1 in OSL. There is no public website for this server.
Share server: A “public” server monitoring everything from Server 2 in FRA. URL: www.akseltelle.com:3001
