Cool. I went another way for monitoring my servers and built a local macOS app instead of installing the monitoring dashboard on the server itself.

It monitors any server you add to it and it can install a daemon that collects metrics for when you are offline. I keep it running to monitor our servers.

Wanted to quickly try this but I couldn't get password authentication to work. No password field appears, and I can't save the server entry since it can't authenticate.
