This topic describes how to use Crash Analytics to view detailed data for crash, stuttering, and abnormal events in a specific application. You can also view the aggregate data for each type of event.
Terms
Aggregate data is data displayed over a specific time period with a dimension of 1 minute, 5 minutes, 1 hour, or 1 day.
For example, if the aggregation time is 1 day, data from the last 7 days is displayed with a 1-day dimension.
For 1-minute and 5-minute aggregations, data from the last 15 minutes is displayed by default.
For 1-hour aggregations, data from the last day is displayed by default.
For 1-day aggregations, data from the last 7 days is displayed by default.
