I have a 2 personal servers with Ubuntu 20.04 that I'd like to build a NodeRed monitoring dashboard for with NodeRed running on my Pi. I'd like to see this sort of info:
ServerName: ONLINE or OFFLINE since $TIMESTAMP CPU used: 30% (or that X Y Z cpu load info) Memory used: 60% /dev/sda1 free: 40% /dev/sda2 free: 90%
So I'd like some way to easily slap an HTTP API on my servers to get this system info in JSON format. Any suggestions? I'm hoping for something that already works and designed for this, that I can install and forget about it, without having to spend ages configuring it.
I know I could use one of those contrib ssh nodes, and use "ssh user@server1 df -h && free -h && whatever-for-cpu" and parse the text output, but I'd rather work with HTTP/JSON than do text parsing tbh.
