title: What should i prefer to log everything, including web app and app service?
body: <p>I need to log everything: application running on app service and app service itself. I see two options App Service Logging and Diagnostic Settings. What should I prefer? And Do I need to make any code change in order to log the app service? And what should I do in order to log the application running on it?
  I just need an overview to make sure I don't mess up.</p>
