Description:General trace and log analysis patterns allow application of uniform problem detection and solving approach across diverse software environments. This pattern language covers any execution artifact from a small debugging trace to a distributed log with billions of messages from hundreds of computers, thousands of software components, threads, and processes. Pattern-oriented trace and log analysis is applicable to troubleshooting and debugging Windows, Mac OS X, Linux, FreeBSD, Android, iOS, z/OS, and any other possible computer platform. Its pattern catalog is a part of pattern-oriented software diagnostics, forensics, and prognostics developed by Software Diagnostics Institute (DumpAnalysis.org + TraceAnalysis.org). This reference reprints with corrections 100 patterns originally published in Memory Dump Analysis Anthology volumes 3 - 8a and Software Diagnostics Library (former Crash Dump Analysis blog, DumpAnalysis.org/blog). Full-color diagrams accompany most pattern descriptions.
