Real Time lets you view events from your app as they come in. By adding a development device’s ID, it can filter for only messages emitted by that device to help you ensure the SDK is properly integrated. You can also filter by message type, and expand an individual message to see more details.
Once you are logged in, on the left sidebar click REAL TIME > SELECT AN APPLICATION.
In the Real Time viewer you can apply a filter to messages. You can apply a blank filter which will show all messages by simply clicking FILTER.
