Codeless Application Insights Custom Counters

Question

I'm running the codeless version of Application Insights in a Windows Server 2016 Azure VM. With the SDK I know it is possible to, for example, add custom telemetry so that I can update the cloudRoleName value that appears in my metrics.

My problem is that for the Performance Counters that are pushed by Application Insights it only provides a value like w3wp#1 for process related data, but I really want to be able to relate this process to an application pool (ideally to a cloudRoleName)

Can I add any configuration to the App Insights agent that will allow me to add custom telemetry or will I have to add the SDK to each of the Dotnet Applications that are running on this VM to achieve this?

If I understand you correctly, you want to provide a custom value for cloudRoleName, right?

If that's the case, the only way is to use code(no way for codeless, see this issue.) by using ITelemetryInitializer, here is an example:

public class CloudRoleNameTelemetryInitializer : ITelemetryInitializer
{
    public void Initialize(ITelemetry telemetry)
    {
      // set custom role name here
      telemetry.Context.Cloud.RoleName = "Custom RoleName";
    }
}
