If you have a chance to attend any presentation or public seminars from the APM vendors, you may come across some demonstrations of how easily to jump from trace to log or log to trace to diagnose a slow API call. This is one of the key differentiation of using a siloed approach for monitoring vs true full stack visibility. Often times, the technical details and prerequisites of how to achieve this are omitted from those overview demos. Today I am going to take a more detail discussion of how to ensure your application can achieve the log to trace correlation. We use DataDog as the example monitoring backend in this exercise.
