EGEM Network Intelligence API

This is the backend service which runs along with EGEM and tracks the network status, fetches information through JSON-RPC and connects through WebSockets to egem-netstats to feed information.

Prerequisite

• geth
• node
• npm

Installation

apt-get install npm -y && sudo npm install -g pm2 && npm install && ln -s /usr/bin/nodejs /usr/bin/node

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"  : "30666", // 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"       : "http://network.egem.io/", // path to egem-netstats WebSockets api server
		"WS_SECRET"       : "EGEM_NETWORK_MAINNET", // 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

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.
