I'm sketching plans to capture select user engagement & related events along with their associated user profile variables to understand user activity on the site, etc using
Mixpanel.
My guess is the best approach vis-a-vis ES related activity would be to clone one of the out-of-the-box ES apps, look for the various trigger handlers and place integration hooks there. Is that right? Where's the best place to look to find a list of all possible triggers / event handlers in ES?
