Enabling Metrics in Nethermind

Metrics can be enabled by simply passing --Metrics.Enabled true argument to the Docker containers,Nethermind.Runner or Nethermind.Launcher e.g. ./Nethermind.Runner --Metrics.Enabled true.

Metrics.PushGatewayUrl will need to be amended if pushgateway endpoint is not default.

Running sample configuration

• clone metrics-infrastructure repository

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

1. go to metrics-infrastructure directory

cd metrics-infrastructure

1. run docker stack

docker-compose up -d

• Prometheus instance should be now running on http://localhost:9090/​

• Pushgateway on http://localhost:9091/​

• Grafana on http://localhost:3000/​

1. run the Nethermind node with Metrics enabled and you should see metrics inflowing on Pushgateway url​

nethermind:
    image: nethermind/nethermind:alpine
    container_name: nethermind
    restart: unless-stopped
    command: '--config goerli --Metrics.Enabled true'
    network_mode: host
    volumes:
        - ./nethermind_db/:/nethermind/nethermind_db/
        - ./keystore/:/nethermind/keystore/
        - ./logs/:/nethermind/logs/

./Nethermind.Runner --Metrics.Enabled true

./Nethermind.Launcher --Metrics.Enabled true

docker run -it --network host nethermind/nethermind:alpine --Metrics.Enabled

1. open Grafana url and login with default login (admin) and password (admin), skip password change if you want

• go to dashboards management http://localhost:3000/dashboardsand click Nethermind

• you can now explore metrics and monitor your Nethermind node
