Read ApplicationInsights.conf
|
var telemetryClient = new TelemetryClient();
// the parameterless ctor calls another ctor with TelemetryConfiguration.Active as parameter
// TelemetryConfiguration.Active reads the ApplicationInsights.config file in the working directory
// Reads a specific ApplicationInsights.config file
TelemetryConfiguration configuration = TelemetryConfiguration.CreateFromConfiguration(File.ReadAllText("C:\\ApplicationInsights.config"));
var telemetryClient = new TelemetryClient(configuration);

Dependency injection
Prism WPF application
| App.xaml.cs |
// classe de type PrismApplication qui hérite de PrismApplicationBase (Prism.DryIoc)
public partial class App
{
protected override void RegisterTypes(IContainerRegistry containerRegistry)
{
var config = TelemetryConfiguration.Active; // Reads ApplicationInsights.config file if present
var telemetryClient = new TelemetryClient(config);
containerRegistry.RegisterInstance(telemetryClient);
}
|
Send telemetry to Application Insights
|
|
// create a dependency
using (telemetryClient.StartOperation<DependencyTelemetry>("Operation name"))
{
}
// log a trace
telemetryClient.TrackTrace("log message");

- Adding the NuGet package Microsoft.ApplicationInsights.Web will automatically log all the incoming Request.
- Long-running background tasks
Link caller dependencies to service incoming requests
- Adding the NuGet package Microsoft.ApplicationInsights.DependencyCollector will propagate the W3C Trace-Context from the caller (client) to the service (controller)

Erreurs
AI: Performance counter is not available in the web app supported list
These warnings are expected as computer level counters are not accessible from the Azure Web App environment. There's no way to turn off any particular counter from the default counters collection, so please safely ignore them as it doesn't affect anything.
AI: Server telemetry channel was not initialized
AI: Server telemetry channel was not initialized. So persistent storage is turned off. You need to call ServerTelemetryChannel.Initialize(). Currently monitoring will continue but if telemetry cannot be sent it will be dropped.
Le fichier ApplicationInsights.config est manquant.
