ember-glimmer-dbmonster-perf.js

/*

	Ensure that you have ember-cli installed
	Clone https://github.com/wycats/dbmonster

	To Run Tests
	 1. Update version on ember to canary (components/ember#canary) or older versions
	 2. Run ember build --environment production
	 3. Run a HTTP server on dist directory, at port 8080
	 4. Run this file to collect data in _data.json
	
	Notes
	 - You may also have to replace this.get('attrs.db') to this.get('db').samples in app/components/dbmon-database.js
	 - You may also have to replace {{attrs.db.name}} to {{db.name}} in app/templates/components/dbmon-database.hbs
