Incorrect Crash Free Sessions stats

What are you trying to accomplish?

Trying to get correct statistics regarding Crash Free sessions.

How are you getting stuck?

It keeps showing a too high number. Often it shows 100% crash free even if we have crashes.

@fredriko-sharkmob thanks for raising this! Could you provide a few more details?

1. Where are you looking at the crash free rate? Is it a Dashboard, or in Discover? Could you share the query you're using?
2. What kind of project do you have? Is it a mobile app? What kind of SDK is it using?
3. Could you share some screenshots or information about what exactly you're seeing, and what you're expecting?

This is likely related to the SDK configuration - transferring.

@fredriko-sharkmob Which SDK and Unreal versions do you use? Did you capture these crashes with UE Crash Reporter or Sentry native integration (check Override Windows default crash capturing mechanism (UE 5.2+) in plugin settings)?

[fredriko-sharkmob]

Hi,

• Sentry plugin version is 0.16.0+. Some entries in the unreleased section in the changelog.md. Highest issue number is Fix invalid assertion issues grouping #537.
• Unreal version 5.4.3. CL 698809.
• Crashes reported with UE Crash Reporter.

@fredriko-sharkmob To track crashed sessions you need to use Sentry's integration instead of Crash Reporter (Release Health docs). Crash Reporter prevents the Sentry plugin from properly marking game sessions as crashed leading to incorrect stats since their error-handling mechanisms are mutually exclusive.
