Maslows Hierarchy of Logging Needs

Episode Summary

Maslow's Hierarchy of Logging establishes a maturity model for software observability, progressing from survival-mode debugging to comprehensive system visibility. Level 1 (Print Statements) offers immediate but ephemeral debugging that creates technical debt through repetitive effort when similar bugs resurface. Level 2 (Logging Libraries) introduces configurable verbosity, persistent debug context, and structured data for querying. Level 3 (Tracing) captures execution paths with timing data for performance profiling. Level 4 (Distributed Tracing) extends this concept across service boundaries, essential for microservice architectures by correlating requests spanning multiple endpoints. Level 5 (Observability) represents full maturity by unifying logs, metrics, and traces with unknown-unknown detection capabilities, providing holistic system visibility with drill-down functionality for anomaly detection across infrastructure, applications, and business processes—conceptually similar to a vehicle dashboard that shows overall status while enabling component-level inspection.
