People I've worked with kinda-sorta understand the advantages of having a trace ID (aka context ID, correlation ID, etc), but don't code it into their systems.

People I've worked with kinda-sorta understand the advantages of having a trace ID (aka context ID, correlation ID, etc), but don't code it into their systems. Or they do something like replace an incoming ID with their own, which negates it's value. For folks who aren't familiar with the concept - at the initiation of any action (user button click, timer firing, automated job starting, etc.) a new ID is created then passed to every single method and external call. This allows you to trace that action as it wends it's way through your distributed systems.
