Microsoft Application Insights for Kubernetes

Nuget Downloads

Application Insights for Kubernetes enhances telemetries with K8s properties, works for .NET Core/.NET 6 applications in Kubernetes clusters.

Screenshot for Application Insights for Kubernetes enhanced telemetry

⚠️ 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 a Kubernetes cluster. However, with 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 microservices/roles on the same application insights map.

Get Started

This is a quick guide for ASP.NET Core projects.


⚠️ For RBAC-enabled Kubernetes, make sure permissions are configured.

Instrument an ASP.NET Core application

⚠️ This is for ASP.NET Core application. See instructions for workers in the Walk-through section below.

  1. Add references 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 deploying Kubernetes Secrets to secure it. Refer to Deploy the application in Kubernetes for an example.

Walk-through with example code

Customize Configurations

Customize configurations are supported. 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].
    ClusterInfoRefreshInterval TimeSpan 00:10:00 For 3.x only. Get or sets how frequent to refresh the Kubernetes cluster properties.
    DisablePerformanceCounters Boolean false Deprecated. Sets to true to avoid adding performance counter telemetry initializer.

Tips: Refer to AppInsightsForKubernetesOptions.cs for the latest customization supported.

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.
