• send all your metrics to Graphite
• benchmark your site against your competitors (comparing specific pages, creating reports, dump the data to Graphite)
• drive WebPageTest (WPT), meaning collect metrics from WPT, create reports and or send the data to Graphite
• test your site against your performance budget
