Création d’une ressource Application Insights dans Azure

    <Add Type="Microsoft.ApplicationInsights.Extensibility.PerfCounterCollector.QuickPulse.QuickPulseTelemetryModule, Microsoft.AI.PerfCounterCollector">
      <QuickPulseServiceEndpoint>Custom_QuickPulse_Endpoint_Address</QuickPulseServiceEndpoint>

</ApplicationInsights>

Modifiez le fichier appsettings.json dans votre projet pour adapter le point de terminaison principal :

"ApplicationInsights": {
    "InstrumentationKey": "instrumentationkey",
    "TelemetryChannel": {
      "EndpointAddress": "TelemetryChannel_Endpoint_Address"
    }
  }

La valeur des points de terminaison Live Metrics et Profile Query ne peut être définie que dans le code. Pour remplacer les valeurs par défaut de tous les points de terminaison en modifiant le code, apportez les modifications suivantes dans la méthode ConfigureServices du fichier Startup.cs :

using Microsoft.ApplicationInsights.Extensibility.Implementation.ApplicationId;
using Microsoft.ApplicationInsights.Extensibility.PerfCounterCollector.QuickPulse; //Place at top of Startup.cs file

   services.ConfigureTelemetryModule<QuickPulseTelemetryModule>((module, o) => module.QuickPulseServiceEndpoint="QuickPulse_Endpoint_Address");

   services.AddSingleton<IApplicationIdProvider, ApplicationInsightsApplicationIdProvider>(_ => new ApplicationInsightsApplicationIdProvider() { ProfileQueryEndpoint = "Profile_Query_Endpoint_address" });

   services.AddSingleton<ITelemetryChannel>(_ => new ServerTelemetryChannel() { EndpointAddress = "TelemetryChannel_Endpoint_Address" });

    //Place in the ConfigureServices method. Place this before services.AddApplicationInsightsTelemetry("instrumentation key"); if it's present

Pour Azure Functions, nous vous recommandons d’utiliser des chaînes de connexion définies dans les paramètres d’application de la fonction. Pour accéder aux paramètres d’application de votre fonction dans le volet des fonctions, sélectionnez Paramètres>Configuration>Paramètre d’application.

Nom : APPLICATIONINSIGHTS_CONNECTION_STRING
Valeur : Connection String Value

Modifiez le fichier applicationinsights.xml pour changer l’adresse du point de terminaison par défaut :

<?xml version="1.0" encoding="utf-8"?>

Spring Boot

Modifiez le fichier application.properties en ajoutant ce qui suit :

azure.application-insights.channel.in-process.endpoint-address= TelemetryChannel_Endpoint_Address

var appInsights = require("applicationinsights");
appInsights.setup('INSTRUMENTATION_KEY');
appInsights.defaultClient.config.endpointUrl = "TelemetryChannel_Endpoint_Address"; // ingestion
appInsights.defaultClient.config.profileQueryEndpoint = "Profile_Query_Endpoint_address"; // appid/profile lookup
appInsights.defaultClient.config.quickPulseHost = "QuickPulse_Endpoint_Address"; //live metrics
appInsights.Configuration.start();

Les points de terminaison peuvent également être configurés à l’aide de variables d’environnement :

**Instrumentation Key*: "APPINSIGHTS_INSTRUMENTATIONKEY"
*Profile endpoint*: "Profile_Query_Endpoint_address"
*Live Metrics endpoint*: "QuickPulse_Endpoint_Address"

L’extrait de code suivant correspond à la version 5. La version y est encodée sous la forme sv:"#". La version actuelle est également disponible sur GitHub.
