How to Monitor AI Agents in Production

Monitoring AI agents in production involves using distributed tracing to track complex interactions within the system, as a single user request can initiate numerous internal operations that logs alone cannot adequately capture. OpenTelemetry's GenAI semantic conventions provide standardized span attributes for Large Language Model (LLM) calls, tool invocations, and agent steps, facilitating a detailed understanding of these processes. Auto-instrumentation libraries such as OpenLLMetry, OpenInference, and OpenLIT simplify the integration of these monitoring capabilities into existing agent frameworks without altering agent code. Traces are sent to OpenObserve via OTLP, where they can be queried with SQL for insights into token usage, cost attribution, and anomaly alerting. The complexity of AI agents compared to single LLM calls makes distributed tracing essential for pinpointing issues related to latency, cost, failures, and quality. OpenTelemetry's conventions and tools like OpenObserve enable comprehensive monitoring and debugging by recording every operation's timing and attributes, providing a full operational record to address these challenges.
