Crash metrics are key indicators of app quality and user satisfaction. The Log Service crash analysis dashboard displays trends for affected users, exceptions, and issues, helping you quickly analyze the impact of crashes and identify their root causes.
Prerequisites
Data must be integrated. For more information, see Integrate Android app monitoring data or Integrate iOS app monitoring data.Procedure
Log on to the Simple Log Service console.
- In the Log Application section, click Mobile App O&M Monitoring.
- In the application list, click the target application.
- In the left-side navigation pane, click Crash Analysis.
Data trends and comparison
The crash analysis dashboard uses line charts and bar charts to display key metrics, including affected users, affected user rate, number of exceptions, exception rate, and exceptions per user.
When you set Time Granularity to Day, clicking a line chart or bar chart takes you to the Issues list, which displays all issues that occurred on that day.
You can also compare crash data across different app versions and time periods. The comparison time ranges must have the same duration, for example, one day or one month.
Top issues
After you select an app version and time range, the system automatically displays issues sorted by Affected Users. This helps you quickly identify the top issues.
You can also filter issues by criteria such as aggregation dimension, status, or assignee.
Issue details
In the Issues list, click an issue to view its details.
- View the main stack trace and key metrics, including app version, affected users, number of exceptions, and exceptions per user.
- Review the number of affected users and exceptions within a specified time range.
- View rankings by multiple dimensions, such as top device models, OS versions, and app versions, to quickly pinpoint common problems.
- Examine the crash report log for device information, app runtime information, and the core crash stack trace to analyze the crashing code and find its root cause.
