Prometheus On Macos

1. Install Prometheus

Install Prometheus with brew install prometheus, the default configuration file is located at: /usr/local/etc/prometheus.yml
Start Prometheus: prometheus --config.file=/usr/local/etc/prometheus.yml. This command runs Prometheus in the foreground, listening on port 9090. Visit http://localhost:9090 in your browser to access the Prometheus Web UI
Alternatively, start Prometheus as a background service:
- Start: brew services start prometheus
- Stop: brew services stop prometheus

What is brew services?

Refer to Launchd for more details.

Install Node Exporter with brew install node_exporter
Start Node Exporter as a background service: brew services start node_exporter. Node Exporter exposes metrics on port 9100: http://localhost:9100/metrics

Edit your Prometheus configuration file and add the following scrape configuration under scrape_configs:

scrape_configs:
  - job_name: 'node_exporter'
    static_configs:
      - targets: ['localhost:9100']

Bug
