Bitshares Health check

Install

npm install -g bitshares-health

Usage

btshealth wss://your-bitshares-node-url
btshealth wss://your-bitshares-node-url --es # defaults to https://your-bitshares-node-url:5000 
btshealth wss://your-bitshares-node-url http://your-es-wrapper-url:5000

Now you (or most likely your LB) can curl for the health state:

curl localhost:3000/
