Ethereum Prometheus Exporter
This service exports various metrics from Ethereum clients for consumption by Prometheus. It uses JSON-RPC interface to collect the metrics. Any JSON-RPC 2.0 enabled client should be supported. Although, it has only been tested with OpenEthereum.
Usage
You can deploy this exporter using the 31z4/ethereum-prometheus-exporter Docker image.
docker run -d -p 9368:9368 --name ethereum-exporter 31z4/ethereum-prometheus-exporter -url http://ethereum:8545
Keep in mind that your container needs to be able to communicate with the Ethereum client using the specified url (default is http://localhost:8545).
By default the exporter serves on :9368 at /metrics. The listen address can be changed by specifying the -addr flag.
Here is an example scrape_config for Prometheus.
