Gain insights into diagnostic techniques and anomaly detection with over 200 trace and log analysis patterns, applicable across various software environments, operating systems, and platforms.

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

# Trace d’enfant
[Causal history](https://www.educative.io/courses/guide-learning-software-trace-log-analysis-patterns/adjoint-anchor-causal-chains-history-messages) messages (black circles) pass through [activity
regions](https://www.educative.io/courses/guide-learning-software-trace-log-analysis-patterns/region-theatre-adjoint-thread-blackout-braid-group), which can be marked as hollow circles.

We call this analysis pattern **trace d’enfant** from analogy with dessin and d’enfant in mathematics, a bipartite graph embedded in an oriented surface. Thus, in theory, traces d’enfants can be studied algebraically.

# Trace path
Trace analysis gestures that result in [CoTrace](https://www.educative.io/courses/guide-learning-software-trace-log-analysis-patterns/foreground-characteristic-cotrace-critical-event) analysis also
produce **trace path** between messages of interest.

Such trace paths can also be useful for [trace homotopy](https://www.educative.io/courses/guide-learning-software-trace-log-analysis-patterns/split-tensor-dimension-extension-homotopy) analysis. They also provide the basis for [explanation traces](https://www.educative.io/courses/guide-learning-software-trace-log-analysis-patterns/order-phase-explanation-factor-focus-fourier).

Note that trace path is also the reverse of the [back trace](https://www.educative.io/courses/guide-learning-software-trace-log-analysis-patterns/backtrace-counter-association-flow-interval) analysis pattern. Both are usually selected from [working set](https://www.educative.io/courses/guide-learning-software-trace-log-analysis-patterns/mask-sharding-similarity-unsynchronized-working).

This lesson introduces the following analysis patterns: trace d’enfant, trace path, traces of individuality, translated message, UI message, and ultrasimilar messages.
