Track telemetry data for your Visual Studio Team Services (VSTS) extension


Get insights in the usage of your extension by leveraging Microsoft Application Insights. Data will only be tracked for extensions running in Visual Studio Team Services (VSTS). If your extension is installed in TFS On-Premise, the calls to Application Insights will be skipped.

See How to integrate Application Insights monitoring in your Team Services extension, which demonstrates how to integrate Application Insights telemetry in your extension by using this package.

Getting Started

  1. Install the package through npm: npm install telemetryclient-team-services-extension

  2. In TypeScript, import the component:

    import * as tc from "TelemetryClient";
  3. Create a configuration object for the telemetryclient. It should contain two values, like this:

    var settings: tc.TelemetryClientSettings = {
        key: "your-key-here",
        extensioncontext: "your-extension-context-here",
        disableTelemetry : "true" or "false",
        disableAjaxTracking  : "true" or "false",
        enableDebug  : "true" or "false"
    • The key is your Application Insights instrumentation key.
    • The extensioncontext is the context for your extension. You can use it to differentiate between multiple extensions in the same Application Insights resource.
    • The disableTelemetry for enabled or disabled telemetry
    • The disableAjaxTracking for enabled or disabled dependencies Ajax disableAjaxTracking
    • The enableDebug for enabled or disabled debuging

    You can see an sample on our extension

    More info on API configuration

  4. Then you can track usage by calling the various methods:



  • Visual Studio Team Services
  • Application Insights resource in Azure
