The Prometheus exporter is enabled by default and installs an HTTP handler on http://localhost:8888/metrics. To read more about configuring the HTTP listener, see .

Example Scrape Config

Add the following configuration to the scrape_configs section inside prometheus.yml of your Prometheus server.

# A scrape configuration containing exactly one endpoint to scrape: 
# Here it's Prometheus itself.
scrape_configs:
  - job_name: 'vernemq'
    scrape_interval: 5s
    scrape_timeout: 5s
    static_configs:
      - targets: ['localhost:8888']

This tells Prometheus to scrape the VerneMQ metrics endpoint every 5 seconds.

Please follow the documentation on the website to properly configure the metrics scraping as well as how to access those metrics and configure alarms and graphs.
