Definitely learned a lot.

This app would be useful if you have more than one device. If you run the monitoring application on the same device as the services you are monitoring and if the device goes down, you wouldn’t get a notification, right?

Depending on the app, there should be option to use server URL where you can put the server’s Tailscale IP and the port.

For Jellyfin, put the Tailscale IP when it asks for server IP and port 8096 like 100.123.45.67:8096
