 One of the APM’s core ideas is the ability to follow the flow of a user session across your whole stack, regardless of whether you have dozens of microservices or a monolith answering your user requests. This implies the ability to tag a request across your entire stack.
 
 To fully capture user activity, you need to start in the browser of the user using Real User Monitoring (RUM) down to your application, which sends a SQL query to your database.
