OpenTelemetry
OpenTelemetry (OTel) is a vendor-neutral, open-source observability framework for generating, collecting, and exporting telemetry data — traces, metrics, and logs — from applications. It provides auto-instrumentation libraries for popular frameworks and a standardized protocol (OTLP) for sending data to any compatible backend (Logfire, Jaeger, Datadog, Grafana). In AI applications, OpenTelemetry traces the full lifecycle of agent requests — from API call through LLM invocation, tool execution, and database queries — providing critical visibility into latency, errors, and resource usage.
