"We’ve re-organized the data you need to make a decision in one place. For example, we now have a single dashboard which tells you how much traffic you receive from Facebook, whether it’s coming from Open Graph stories or Requests. We realize that it’s difficult to make decisions in a vacuum. Now, you can compare key metrics for your app to those for other apps. For example, if you see an abnormal spike in the mark-as-spam rate for your app’s stories, you can see if the spike is isolated to your app or if other apps also see the spike. Note: metrics are aggregated and anonymized – Insights will never show your app’s metrics to another developer."
Facebook noted that the company will still continue to make improvements to App Insights by bringing in more features from the previous version as well as adding new features. For now, App Insights 1.0 will be the default option. To try the beta product, go to the App Insights overview page and click “try the new App Insights.”
