Application Insights–Change the application name in the Application Map

When you use the default configuration in Application Insights, the default role name (on-premise) used is the name of your Application Insights resource:

This is not that meaningful especially because right now our frontend and backend telemetry is shown together. Let’s fix this by introducing a TelemetryInitializer. In this TelemetryInitializer we update the RoleName:

• Create an initializer in both the frontend and backend project:

	public class ServiceNameInitializer : ITelemetryInitializer
	{
	public void Initialize(ITelemetry telemetry)
	{
	telemetry.Context.Cloud.RoleName = "FrontEndApp";
	}
	}

• Don’t forget to change the role name accordingly.
• Load this initializer in your global.asax:

	TelemetryConfiguration.Active.TelemetryInitializers
	.Add(new ServiceNameInitializer());

· Run the application again

Remark: You’ll have to wait some time before the updated names show up on the Application map
