Microsoft Application Insights for Kubernetes

This repository has code for Application Insights for Kubernetes, which works on .NET Core applications within the containers, managed by Kubernetes, on Azure Container Service.

Note: Microsoft Application Insights for Kubernetes (this library) is an enhancement to the Microsoft Application Insights. You can choose to run Application Insights without this library in Kubernetes cluster too. However, when using Microsoft Application Insights for Kubernetes, you will see Kubernetes related properties like Pod-Name, Deployment ... on all your telemetry entries. Proper values will also be set to make use of the rich features like enabling the Application Map to show the multiple micro services on the same map.

Get Started


Instrument an ASP.NET Core application

These are the basic steps to instrument an ASP.NET Core application to enable Application Insights for Kubernetes. You will need to run the application in containers managed by Kubernetes to see the change.

  1. Add reference to Application Insights SDK and Application Insights for Kubernetes:

    dotnet add package Microsoft.ApplicationInsights.AspNetCore
    dotnet add package Microsoft.ApplicationInsights.Kubernetes
  2. Enable Application Insights and Application Insights for Kubernetes Enricher in Startup.cs:

    public void ConfigureServices(IServiceCollection services)
        services.AddApplicationInsightsTelemetry("----Your Application Insights Instrumentation Key ----");
  3. Build the application in containers, then deploy the container with Kubernetes.

Notes: Those steps are not considered the best practice to set the instrumentation key for application insights. Refer to Enable Application Insights server-side telemetry for various options. Also, consider deploy Kubernetes Secrets to secure it.


Both ASP.NET Core and .NET Core applications are supported.

  • For ASP.NET Core Application: Refer to Getting Started for a simple walk-through.

  • For .NET Core Application: Refer to Getting Started for a simple walk-through.

  • Follow this example for Role-based access control (RBAC) enabled Kubernetes clusters.

Configuration Details

Customize configurations are supported starting with version 1.0.2 of the ApplicationInsights.Kubernetes package. There are several ways to customize the settings. For example:

  1. Using code:

    services.AddApplicationInsightsKubernetesEnricher(option=> {
        option.InitializationTimeout = TimeSpan.FromSeconds(15);
  2. Using appsettings.json:

        "Logging": {
            // ...
        // Adding the following section to set the timeout to 15 seconds
        "AppInsightsForKubernetes": {
            "InitializationTimeout": "00:00:15"
  3. Using environment variables:


    All the related configurations have to be put in a section named AppInsightsForKubernetes. The supported keys/values are listed below:

    Key Value/Types Default Value Description
    InitializationTimeout TimeSpan 00:02:00 Maximum time to wait for spinning up the container. Accepted format: [d.]hh:mm:ss[.fffffff].
    DisablePerformanceCounters Boolean false Sets to true to avoid adding performance counter telemetry initializer.

The configuration uses the ASP.NET Core conventions. Refer to Configuration in ASP.NET Core for more information.

Verify the cluster configuration (Linux Container only)

Use the troubleshooting image to verify the cluster is properly configured.
