OpenTelemetry-native observability for agents and LLMs
AI Observability by OpenObserve is a comprehensive, OpenTelemetry-native platform designed to provide deep insights into the performance and reliability of AI agents, especially those involving large language models (LLMs). It enables developers and operations teams to trace every session across models, tools, services, and data stores, offering a unified view of system health, costs, and execution flow. By capturing logs, traces, and metrics, it helps identify bottlenecks, detect loops, and follow failures from the LLM call through to backend processes and databases. This level of observability empowers teams to optimize agent performance, reduce costs, and improve overall quality. Its seamless integration with existing stacks makes it especially valuable for organizations deploying complex AI workflows and needing detailed operational transparency.
