With architectures becoming more distributed and code more asynchronous, pinpointing and resolving errors in production is harder than ever. In this article we investigate five advanced techniques that can help you get to the root cause of painful bugs in production more quickly, without adding material overhead.
Takipi is trying to level out the playing field between dev and prod debugging by making it just as easy to debug Java and Scala code in production as it is on your desktop. It detects errors and exceptions in server code, provides analytics to help prioritize them, and captures the source code and values of variables that caused them.
A debugger is a great tool for examining the internal state of an application, reproducing however a specific issue is a completely different matter. Fully replicating the production environment into a staging area might even be a feat on its own. Meet recording debuggers that remove all the guesswork and extra effort by monitoring the application in production and knowing exactly what happened.
Tess Ferrnandez, an escalation engineer in PSS (product support services) at Microsoft, outlines the procedure for tracking down where in your code an exception occurred by using a stack dump.
