I had a similar need, and after going through the docs for a few existing solutions (grafana, elastic, prometheus, etc) I decided to roll my own.

No db on the receiver and log-based storage on the senders (using standard log rotation to manage size). A systemd service to write to logs, another to read the last value and push to remote if it has changed. Bash all around.

Other than absolutely 0 maintenance required, and just a $5 droplet, the thing I like the most is the dashboard. It just looks like a spreadsheet. A row for each server, a column for each metric. Click on a cell to view charts for that metric. If metrics are failing health checks cell goes orange, or red if critical. Otherwise it's all gray.

So I can have the dashboard open on a screen and just glance at it and know if something is off. I haven't seen anyone else providing such a dashboard, maybe you can give it a go:)

This is an interesting use case. I can definitely see how a colored cell in a grid can serve as a visual indicator to monitor health of infrastructure. Thanks for sharing this.
