General trace and log analysis patterns allow the application of uniform diagnostics and anomaly detection across diverse software environments. It includes troubleshooting, debugging, describing, and explaining problems and incidents on various operating systems and platforms. It is also helpful in recording network traces, malware, general data, narratives, and text and image analysis (space-like narratology). This course, organized as a pattern language dictionary and cross-referenced with classification, explains and teaches more than 200 traces and log analysis patterns.

A Guide to Learning Software Trace and Log Analysis Patterns

## Drone message
Sometimes we see a constantly repeated message throughout a trace or log
(a trivial [periodic message block](https://www.educative.io/courses/guide-learning-software-trace-log-analysis-patterns/periodic-message-renormalisation-significant)) with a constant [time delta](https://www.educative.io/courses/guide-learning-software-trace-log-analysis-patterns/ruptured-strand-thread-time-delta-timeout-weave). In certain trace forms (without explicit timing information), such
messages may indicate internal time references as illustrated in the
following diagram:
