Monitoring and Metrics

Ethrex exposes metrics in Prometheus format on port 9090 by default. The easiest way to monitor your node is to use the provided Docker Compose stack, which includes Prometheus and Grafana preconfigured.

Quickstart: Monitoring Stack with Docker Compose

1. Clone the repository:

   git clone https://github.com/lambdaclass/ethrex.git
   cd ethrex/metrics
   

2. Start the monitoring stack:

   docker compose -f docker-compose-metrics.yaml -f docker-compose-metrics-l1.overrides.yaml up -d
   

This will launch Prometheus and Grafana, already set up to scrape ethrex metrics.

Accessing Metrics and Dashboards

• Prometheus: http://localhost:9091
• Grafana: http://localhost:3001
  • Default login: admin / admin
  • Prometheus is preconfigured as a data source
  • Example dashboards are included in the repo

Metrics from ethrex will be available at http://localhost:9090/metrics in Prometheus format.

Custom Configuration

Your ethrex setup may differ from the default configuration. Check your endpoints at provisioning/prometheus/prometheus_l1_sync_docker.yaml.

For manual setup or more details, see the Prometheus documentation and Grafana documentation.
