I am looking to use the TrackTrace method associated with Telemetry client. An instance of TelemetryClient needs to be created in order to access this method.
A TelemetryClient can be initialised in the constructor of a controller but I was looking to see if there is a better approach and how it would be implemented?
Quote from Microsoft Docs:
Get an instance of TelemetryClient by using constructor injection, and call the required TrackXXX() method on it. We don't recommend creating new TelemetryClient instances in an ASP.NET Core application.
A singleton instance of TelemetryClient is already registered in the DependencyInjection container, which shares TelemetryConfiguration with rest of the telemetry. Creating a new TelemetryClient instance is recommended only if it needs a configuration that's separate from the rest of the telemetry.
So you can just get it injected wherever you need like this:
using Microsoft.ApplicationInsights;
public class HomeController : Controller
{
private TelemetryClient telemetry;
// Use constructor injection to get a TelemetryClient instance.
public HomeController(TelemetryClient telemetry)
{
this.telemetry = telemetry;
}
public IActionResult Index()
{
// Call the required TrackXXX method.
this.telemetry.TrackEvent("HomePageRequested");
return View();
}
