DISCLAIMER: this is a copied (and improved) version of the official lighthouse-metrics repo.

Lighthouse Metrics

Provides a docker-compose environment which scrapes metrics from Lighthouse nodes using Prometheus and presents them in a browser-based Grafana GUI.

Usage

This guide expects you to be running the official lighthouse docker-compose environment.

1. Bring the environment up with docker-compose up -d.
2. Ensure that Prometheus can access your Lighthouse nodes by ensuring they are in the UP state at http://localhost:9090/targets. Both http://beacon_node:5054/metrics and http://validator_client:5064/metrics needs to be in the UP state
3. Browse to http://localhost:3000
   • Username: admin
   • Password: changeme
4. Import any dashboard from the dashboards directory in this repo:
   • In the Grafana UI, go to Dashboards -> Manage -> Import -> Upload .json file.
   • The Summary.json dashboard is a good place to start.

Grafana and Prometheus will be running on the same network as the official lighthouse-docker containers and will persist any data in the two grafana and prometheus folders of this repo.

Hosting Publicly

By default Prometheus and Grafana will only bind to localhost (127.0.0.1), in order to protect you from accidentally exposing them to the public internet. If you would like to change this you must edit the http_addr in grafana.ini.

Prometheus

The scrape-targets.json file is periodically read by Prometheus and specifies the targets it should watch.

If you want to add a node to the metrics service, do it there.
