PM2 test files for log4js-node issue #265

pm2.js

const log4js = require('../lib/log4js');

// NOTE: for PM2 support to work you'll need to install the pm2-intercom module
// `pm2 install pm2-intercom`
log4js.configure({
  appenders: {
    out: { type: 'file', filename: 'pm2logs.log' }
  },
  categories: {
    default: { appenders: ['out'], level: 'info' }
  },
  pm2: true,
  pm2InstanceVar: 'INSTANCE_ID'
});

const logger = log4js.getLogger('app');
setInterval(() => {
  logger.info("I'm forever blowing bubbles");
}, 1000);

pm2.json

{ "apps": [
  { "name": "testing",
    "script": "pm2.js",
    "instances": 0,
    "instance_var": "INSTANCE_ID",
    "exec_mode": "cluster"
    }
    ]
  }

node v8.2.1, pm2 2.6.1, pm2-intercom 1.0.0

npm install -g pm2
pm2 install pm2-intercom
pm2 start pm2.json

I was running this in my local log4js-node, from the examples directory (hence the '../lib/log4js' path in the require).
