How to install Prometheus on OS-X

Install prometheus

  • Download the compiled prometheus binaries from prometheus.io
  • Unzip the binary and cd into the directory.
  • 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
  • From a local browser, point to localhost:9090
prometheus web-ui

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

  • Unzip the tar.gz
  • cd into the directory
  • run the node exporter
$ cd /Users/gary.little/Downloads/node_exporter-0.18.1.darwin-amd64
$ ./node_exporter
