Table of contents` is a section in the provided text that highlights the importance of observability alongside monitoring for Large Language Models (LLMs) as, as of 2024, 75% of businesses using LLMs plan to integrate observability tools to enhance real-time monitoring and diagnostics. Observability delves into the "why" behind performance issues, enabling deeper investigation into root causes and component interactions, while monitoring tracks predefined metrics such as response times, throughput, and resource utilization, answering "what" is happening in the application. Integrating both monitoring and observability enables teams to ensure not only that their systems are running smoothly but also that they understand them well enough to make continuous enhancements and preemptively address potential issues.
