Run the prometheus binary, from the command line, it will listen on port 9090
$ cd /Users/gary.little/Downloads/prometheus-2.16.0-rc.0.darwin-amd64 $ ./prometheus

Add a collector/scraper to monitor the OS
Prometheus itself does not do much apart from monitor itself, to do anything useful we have to add a scraper/exporter module. The easiest thing to do is add the scraper to monitor OS-X itself. As in Linux the OS exporter is simply called “node exporter”.
Start by downloading the pre-compiled darwin node exporter from prometheus.io
