Grafana and Prometheus

This guide will walk you through setting up a local metrics infrastructure using Grafana and Prometheus.

Step 1: Set up Grafana and Prometheus

To simplify the process, we will use the metrics-infrastructure repository, which contains the necessary configuration files to run Grafana and Prometheus in a Docker container. However, you can also set up Grafana and Prometheus manually the way it fits your specific needs.

git clone https://github.com/NethermindEth/metrics-infrastructure.git

Step 2: Run the stack

After cloning the repository, navigate to its root directory and run the containers using Docker Compose as follows:

docker-compose up

Once the stack is running, you can access the following services:

  • Grafana: localhost:3000
    Use admin for both the username and password. When asked for a password change, you may skip it. Then, navigate to Dashboards > Nethermind Dashboard.
  • Prometheus: localhost:9090
  • Pushgateway: localhost:9091
    To specify another endpoint for the Pushgateway, use the --Metrics.PushGatewayUrl command line option.

Step 3: Run Nethermind

To enable metrics in Nethermind, use the --Metrics.Enabled true command line option. For more options, see the Metrics configuration section.

Important

A consensus client of your choice must be running before you start Nethermind.

Run Nethermind as follows:

nethermind -c mainnet --Metrics.Enabled true

Alternatively, you may add the nethermind service to the docker-compose.yml file in the repository root to run everything altogether:

docker-compose.yml
nethermind:
image: nethermind/nethermind:latest
container_name: nethermind
restart: unless-stopped
ports:
- 8545:8545
- 8551:8551
- 30303:30303
ulimits:
nofile:
soft: 1000000
hard: 1000000
command: -c mainnet --Metrics.Enabled true
volumes:
- ./keystore:/nethermind/keystore
- ./logs:/nethermind/logs
- ./nethermind_db:/nethermind/nethermind_db

In this case, you may want to configure your consensus client similarly.
