Filter out fatal exceptions before send to Sentry from .Net Maui application - Stack Overflow

I want only to send Fatal exceptions (when app crashes) to Sentry. If I remove the SetBeforeSent everything is sent, if I have it nothing is sent.

    .UseSentry(options =>
    {
       options.Dsn = App.SentryDsn;
       options.DiagnosticLevel = SentryLevel.Fatal;
       options.IsGlobalModeEnabled = true;
       options.SetBeforeBreadcrumb((sentryEvent, hint) =>
       {                
          if (sentryEvent.Category == "Microsoft.Maui.Controls.Xaml.Diagnostics.BindingDiagnostics")
          {
             return null;
          }                    

          return sentryEvent;
       });
       options.SetBeforeSend((sentryEvent, hint) =>
       {
          if (sentryEvent?.Level == SentryLevel.Fatal)
          {
             return sentryEvent;
          }
          return null;
       });
    })

I try to configure scope when catching exceptions to set it to Fatal but it doesn´t have any effect.

SentrySdk.ConfigureScope(scope =>
{
    scope.Level = SentryLevel.Fatal;                
});
SentrySdk.CaptureException(ex);

Someone who has a good idea off what's wrong?

• If you set Debug = true; does it help you understand what the SDK is doing? – Bruno Garcia Commented Apr 1 at 22:05

To get only events that are crashes you need to check if the event has an exception with the flag handled: false. It's a bit involved since you need to check evt.SentryExceptions.FirstOrDefault()?.Handled or something (I didn't try this out).

In .NET MAUI, unhandled C# exceptions generally crash the app. So you should anyway be only getting crashes out of the box. What types of events are you trying not to capture?

It might be that you're capturing LogError as events and you want to drop those?

If so try just setting:

options.MinimumEventLevel = SentryLevel.Fatal;

That's configuring the Sentry SDK for MAUI's integration with Microsoft.Extensions.Logging. Docs on this are here. This specific setting is here.

Note that:

       options.DiagnosticLevel = SentryLevel.Fatal;

Only controls what SDK internal logs get printed out to the console (or logcat, etc). That's documented here. And in general the diagnostic logger docs are here.

This helped me to catch unhandled exceptions.

.UseSentry(options =>
{
  options.SetBeforeSend((sentryEvent, hint) =>
  {
    if (sentryEvent?.SentryExceptions.FirstOrDefault()?.Mechanism.Handled == false)
    {
        return sentryEvent;
    }
    return null;
  });

MinimumEventLevel is of type Microsoft.Extensions.Logging LogLevel not SentryLevel, I tried to set it to LogLevel.Critical but is not sure if it did help.

options.MinimumEventLevel = LogLevel.Critical;

The reason it did not work to set SentryLevel.Fatal was that the SetBeforeSend did not get the modified exception.

SentrySdk.ConfigureScope(scope =>
{
    scope.Level = SentryLevel.Fatal;                
});
SentrySdk.CaptureException(ex);

options.SetBeforeSend((sentryEvent, hint) =>
       {
          if (sentryEvent?.Level == SentryLevel.Fatal)
          {
             return sentryEvent;
          }
          return null;
       });
