Large Language Model (LLM) monitoring often fails under the pressure of production due to its design for controlled settings rather than the unpredictable nature of serving millions of diverse users. The complexity increases at an enterprise scale, where AI-specific centralized monitoring is essential to prevent cascading system failures. The text outlines seven strategies to enhance LLM performance monitoring, emphasizing the importance of tracking quality and consistency metrics, user experience, system performance, and latency indicators. Strategies include implementing statistical and distribution-based drift detection, behavioral and semantic drift monitoring, and smart alerting systems to reduce false positives. It also highlights the need for efficient response workflows for reliability incidents. The guide underscores the role of advanced tools like Galileo in providing unified quality monitoring, advanced drift detection, and context-aware alerting to maintain LLM reliability at scale.
