Chainlink Node Metrics

Lightweight server that fetches metrics from a Chainlink node and returns the result in InfluxDB line protocol syntax. Simplifies monitoring in a dockerized environment.

Configuration

See .env.example for all available configuration options.

npm run dev

Docker

docker run --rm -p 8080:8080 -e "CHAINLINK_HOST=http://localhost:6688" -e "CHAINLINK_EMAIL=YOUR_API_EMAIL" -e "CHAINLINK_PASSWORD=YOUR_API_PASSWORD" anyblockanalytics/chainlink-node-metrics:latest

Endpoints

  ]
