Observability: A brilliant idea whose name has been hijacked

Observability, a concept introduced by Rudolf E. Kálmán in 1960 for aerospace and industrial systems, has been adapted for modern software systems to help developers understand internal states through external outputs like logs, metrics, and traces. As software complexity and user diversity have increased, developers have needed tools that can capture unexpected behaviors in live systems, leading to the development of platforms like Honeycomb, Dynatrace, and Axiom. However, the term "Observability" has been diluted by companies offering legacy monitoring tools that rely on sampling and filtering, which limits the ability to detect unforeseen issues. Axiom aims to address this by providing a logging system that centralizes 100% of event data, offering full visibility without the compromises seen in other monitoring solutions, and inviting developers to explore their pricing plans to achieve true Observability.
