Simple Metrics Generator

Simple Prometheus metrics generator.

Usage

cat metadata | generate_metrics tempurature 50

with your metadata file looking something like

unit="F", computer="computer5"

From here you could then redirect stdout into a file, then host the file with something like Caddy for Prometheus to scrape.

A simple "down detector". Put this in a crontab (runs every minute):

* * * * * cat /etc/metrics_metadata | generate_metrics cloudflare $(ping -c 1 1.1.1.1 &> /dev/null ; echo $?) > /srv/metrics/cloudflare

:80 {
	root * /srv/metrics
	file_server
}
