Crash-Free Rates are one of the most important metrics for any mobile app. Setting up these alerts allows you to proactively detect and address stability issues, ensuring a smoother user experience. They provide quick insights into problematic app versions, enabling faster resolution and better decision-making.

Crash-Free Sessions

Set a threshold and get alerted whenever the application’s crash-free sessions rate drops below the specified threshold.

1. Trigger:

   • Select "Crash-free sessions in the last 24 hours".

     

     
     

2. Select the Threshold for Crash-Free Sessions: Any drop below this point will trigger an alert.

   

   
   

3. Breakout by App Version: (Optional)

   • By toggling "Send an alert for every app version," you will get alerted for every app version that has its crash-free sessions rate drop below the threshold.

4. Conditions:

   • If no condition is added, the rule will be applied to the app/app version if it exceeds 100 sessions.

   • You have 2 conditions you can choose from:

     

     
     
     • App Version: Select "Top Releases" or "Latest Releases", or specify app versions.

     

     
     

     • Session count: The minimum number of sessions the app (or selected versions) has to have for the alert to trigger. Specify "Greater than" or "Less than" to set a number of sessions and reduce the noise.

       

       
       

5. Forward Alert:

   • Set the option to forward the alert to your favorite integrated tool.
