The Realtime dashboard is the first you are met with when entering the game.
Here you will find the most essential user and error metrics based on the data for the past 24 hours. Also, you will see core metrics based on the data aggregated no later than 5 minutes ago (unless there are processing delays, see here the status of the tool).
The top of the dashboard breaks down in a hourly timeframe the SDK(s) integrated and the concurrent users and events logged. This gives a great overview of the unique users at this very moment and that event are logged correctly.
Further down the page you will find the breakdown of users and potential conversion and revenue numbers. This provides a quick at a glance view of your game – right now.
Lastly, you will find the session and events break down grouped by severity to help you debug any potential errors in your instrumentation.
