🦄 Ethereum Metrics Exporter 🦄

A Prometheus metrics exporter for Ethereum execution & consensus nodes

Ethereum client implementations expose extensive Prometheus metrics however there is minimal standardization around the metrics structure. This makes observability across multiple clients a painful experience. This exporter hopes to help alleviate this problem by creating a client-agnostic set of metrics that operators can run without any additional configuration to dashboards or alerting.

To provide these client-agnostic metrics the exporter relies entirely on these well-defined APIs:

• Execution clients
  • JSON-RPC
• Consensus clients
  • Beacon Node API

Naturally this means that the exporter is limited to metrics that are exposed by these APIs.

Built With

• pf13/cobra-cli
• ethereum/go-ethereum
• attestantio/go-eth2-client
