Ethereum Network Intelligence API "Classic"

[![Build Status][travis-image]][travis-url] [![dependency status][dep-image]][dep-url]

This is the backend service which runs along with ethereum and tracks the network status, fetches information through JSON-RPC and connects through WebSockets to eth-netstats (Ethereum Network Stats "Classic") to feed information.

For full install instructions please read the wiki.

Prerequisite

• eth, geth or pyethapp
• node
• npm

Installation on an Ubuntu EC2 Instance

Fetch and run the build shell. This will install everything you need: latest ethereum - CLI from develop branch (you can choose between eth or geth), node.js, npm & pm2.

bash <(curl https://raw.githubusercontent.com/ethereum/eth-net-intelligence-api/master/bin/build.sh)

Installation as docker container (optional)

There is a Dockerfile in the root directory of the repository. Please read through the header of said file for instructions on how to build/run/setup. Configuration instructions below still apply.

Configuration

Configure the app modifying app.json

"env":
	{
		"NODE_ENV"        : "production", // tell the client we're in production environment
		"RPC_HOST"        : "localhost", // eth JSON-RPC host
		"RPC_PORT"        : "8545", // eth JSON-RPC port
		"LISTENING_PORT"  : "30303", // eth listening port (only used for display)
		"INSTANCE_NAME"   : "", // whatever you wish to name your node
		"CONTACT_DETAILS" : "", // add your contact details here if you wish (email/skype)
		"WS_SERVER"       : "wss://rpc.ethstats.net", // path to eth-netstats WebSockets api server
		"WS_SECRET"       : "see http://forum.ethereum.org/discussion/2112/how-to-add-yourself-to-the-stats-dashboard-its-not-automatic", // WebSockets api server secret used for login
		"VERBOSITY"       : 2 // Set the verbosity (0 = silent, 1 = error, warn, 2 = error, warn, info, success, 3 = all logs)
	}

Run

Run it using pm2:

pm2 start app.json

Then run app.js:

node app.js

Use ctrl+c to stop the process.

Updating

To update the API client use the following command:

~/bin/www/bin/update.sh

It will stop the current netstats client processes, automatically detect your ethereum implementation and version, update it to the latest develop build, update netstats client and reload the processes.
