Um eigene Werte in Application Insights loggen zu können, muss ein eigener ITelemetryInitializer erzeugt werden.
Dieser dient nun dazu, dass der entsprechende Log-Kontext um Informationen angereichert werden können:
1 public class MyCustomTelemetryInitializer : ITelemetryInitializer
2 {
3 public void Initialize(ITelemetry telemetry)
4 {
5 if (telemetry is RequestTelemetry requestTelemetry) // wenn ich nur Request Telemtry erweitern möchte
6 {
7 requestTelemetry.Context.GlobalProperties.Add("MyLogField",
8 "MyLogValue");
9 }
10 }
11 }Dieser muss anschließend noch registriert werden
services.AddSingleton<ITelemetryInitializer, MyCustomTelemetryInitializer>();Achtet bei der Implementierung darauf, dass der Wert als String gespeichert wird. Das bedeutet, dass entsprechend eine neutrale Lokalisierung verwendet werden sollte und auch Zeitstempel sich nach ISO8601 orientieren sollten!
