Dynatrace provides comprehensive web request monitoring for MAUI applications. You can automatically instrument HTTP requests via HttpClient or manually report requests from unsupported libraries.

Enable automatic web request instrumentation

You can optionally use the following method to enable the auto-instrumentation of web requests. The HttpMessageHandler used by HttpClient takes care of the manual web request instrumentation.

using Dynatrace.MAUI;


var httpHandler = Agent.Instance.GetHttpMessageHandler();
var httpClient = new HttpClient(httpHandler);

Moreover, you can also have your own HTTP handler:

using Dynatrace.MAUI;


var defaultHttpHandler = new HttpClientHandler();
var httpHandler = Agent.Instance.GetHttpMessageHandler(defaultHttpHandler);
var httpClient = new HttpClient(httpHandler);

Instrument web requests

Use the following code snippet to instrument web requests:

using Dynatrace.MAUI;


// Create an action
IRootAction webAction = Agent.Instance.EnterAction(actionName: "WebRequest Action");
// Generate a new unique tag associated with the web request action
string requestTag = webAction.GetRequestTag(url);
string requestTagHeader = webAction.GetRequestTagHeader();
// Place the Dynatrace HTTP header on your web request
httpClient.DefaultRequestHeaders.Add(requestTagHeader, requestTag);
// Generate a WebRequestTiming object based on the unique tag
IWebRequestTiming timing = Agent.Instance.GetWebRequestTiming(requestTag, url);
// Start web request timing before the HTTP request is sent
timing.StartWebRequestTiming();
try
{
  var response = await httpClient.GetAsync(url);
  // Stop web request timing when the HTTP response is received and the response body is obtained
  timing.StopWebRequestTiming(url, (int)response.StatusCode, response.ReasonPhrase);
}
catch (HttpRequestException exception)
{
  // Stop web request timing when a connection exception occurs
  timing.StopWebRequestTiming(url, -1, exception.ToString());
}
finally
{
  // Leave an action
  webAction.LeaveAction();
}
