Dynatrace provides comprehensive app performance monitoring for MAUI applications. This includes tracking app startup times, monitoring navigation between screens, and capturing view-level metrics that help you understand user experience and identify performance bottlenecks.

App start event

The app start event is automatically captured by the native OneAgent when your application launches. This event provides insights into how long it takes for your app to become usable.

What is captured

The native Android and iOS agents automatically capture:

Cold start—time from app process creation to the first frame rendered.
Warm start—time when the app is brought back from the background.
App lifecycle events—key milestones during the startup process.

Configuration

App start monitoring is enabled by default. No additional configuration is required in your .NET MAUI code. The native agents handle this automatically.

View monitoring

Views represent individual screens of content in your application. Tracking views helps you understand user navigation patterns, identify slow-loading screens, and contextualize errors and performance issues.

MAUI only supports manual instrumentation of views at this time.

Manual view instrumentation

Use the StartView() method to manually track when a user enters a new screen:

using Dynatrace.MAUI;

public partial class MainPage : ContentPage
{

    public ProductDetailPage()
    {
        InitializeComponent();
        Agent.Instance.StartView("ProductDetailPage");
    }
  }

Use consistent, meaningful view names across your application. For example: HomePage, ProductListPage, ProductDetailPage, CheckoutPage, OrderConfirmationPage.

View behavior

Single active view—only one view can be active at a time. Starting a new view automatically stops the previous one.
Event association—all events captured after StartView() are associated with that view until another view is started.
Empty names ignored—calls to StartView() with an empty string are ignored.

ANR reporting

Application Not Responding (ANR) errors occur when the main thread is blocked for too long, causing the app to become unresponsive. Dynatrace automatically captures ANR events.

Configuration

ANR reporting is enabled by default. To disable it, update your dynatrace.config.json:

{
  "android": {
    "autoStart": {
      "beaconUrl": "https://...",
      "applicationId": "..."
    },
    "anrReporting": false
  },
  "ios": {
    "DTXBeaconUrl": "https://...",
    "DTXApplicationId": "...",
    "DTXANRReportingEnabled": false
  }
}

ANR events are only sent if the user restarts the app within 10 minutes of the ANR occurring.
