This episode examines modern software maintenance practices, specifically Monitoring and Observability, through the lens of Masonic symbolism to illustrate principles of operational wisdom. Monitoring is aligned with the Watchtower, focusing on tracking real-time quantitative data about known system conditions, much like a Tiler guards a perimeter to detect anticipated problems. In contrast, Observability is compared to the All-Seeing Eye and the Mirror, representing the capacity to ask questions about a system’s inner workings to troubleshoot novel problems or “unknown unknowns.” Together, these concepts constitute the operational wisdom required by Site Reliability Engineers (SREs), which is further mapped onto the Masonic pillars of Wisdom, Strength, and Beauty to guide the pursuit of system reliability, efficiency, and continuous improvement.
