Exception Stack, False Positive, Hidden, Periodic
Explore how to analyze software traces by recognizing exception stack traces, distinguishing false positive errors, detecting hidden errors through indirect signs, and understanding periodic errors. This lesson helps you develop skills to accurately interpret log behaviors and improve root cause analysis in diverse software environments.
We'll cover the following...
Exception stack trace
Often the analysis of software traces starts with a search for short textual patterns, like a failure, an exception code, or simply the word “exception.” In addition, some software components can record their own exceptions and exceptions that were propagated to them, including full-stack traces. It is all too common in .NET and Java environments. Here is a synthetic example based on real software traces:
In the embedded stack trace, we see that the App object was trying to enumerate business objects and asked the Store object to get some data. The latter object was probably trying to communicate with the real data store via DCOM. The communication attempt failed with HRESULT.
In the previous pattern example, a stack trace was inside a ...
