Etherium healthcheck for HAProxy via Etherium HTTP JSON-RPC API.
You will need go-lang version 1.14 or later to compile the source.
When starting the tcp server you can specify what address and port it should listen to:
eth-healthcheck <ip> <port>
by default it will listen to 127.0.0.1:1301
The healthcheck server can check any Etherium client that supports the JSON-RPC API via HTTP. Here is the documentation for the popular geth client.
You will need to tell haproxy to send a message to the tcp server with the HTTP url to a etherium client's JSON-RPC API that you would like to check.
This url should be passed to the agent-send parameter in HAproxy config like this:
check agent-check agent-addr 127.0.0.1 agent-port 1301 agent-send "http://127.0.0.1:8545\n"
