What is API Observability

API Observability is crucial for effectively executing APIOps Cycles by providing a comprehensive view into both the engineering and business aspects of APIs, allowing for improved troubleshooting and strategic insights. Unlike traditional monitoring, which measures known unknowns such as Requests Per Second, API Observability stems from control systems theory and enables the analysis of unknown unknowns by inferring system state and behavior from outputs. This advanced approach allows teams to answer arbitrary questions about their APIs' performance and business impact, integrating metrics across physical infrastructure and broader business inputs like revenue and customer demographics. Using sophisticated analytics tools like Moesif, organizations can generate on-the-fly reports and gain a deeper understanding of API usage, customer behavior, and business outcomes, extending the scope of observability to entire products or business units.
