Amazon SageMaker has introduced a comprehensive observability solution for large language model (LLM) inference, enabling detailed monitoring of both infrastructure and model quality. The new tools provide real-time insights into GPU utilization, latency, and response accuracy, helping teams manage and optimize AI workloads effectively. According to the blog post, observability is critical for production machine learning strategies, especially with LLMs that generate variable outputs. The solution uses three core AWS services—Amazon SageMaker AI endpoints, Amazon CloudWatch, and Amazon Managed Grafana—to monitor both the operational health of inference infrastructure and the performance of LLMs themselves. Quantity monitoring tracks request throughput and resource usage, while quality monitoring evaluates response accuracy and compliance. These metrics are essential for identifying bottlenecks, controlling costs, and ensuring reliable service delivery. The observability approach also supports comparative analysis across models and configurations, allowing continuous tuning of cost, performance, and output quality. The blog post highlights the use of Amazon Managed Grafana dashboards to visualize these metrics, offering a holistic view of both quantity and quality for LLMs served on SageMaker AI endpoints. *Source: [awsml](https://aws.amazon.com/blogs/machine-learning/comprehensive-observability-for-amazon-sagemaker-ai-llm-inference-from-gpu-utilization-to-llm-quality/)*
