# Practical ways to use the Claude Agent SDK 📊 Visualize all agent activity in Datadog, Grafana, or Langfuse with OpenTelemetry. OpenTelemetry Observability exports agent traces, metrics, and logs via OTLP to external monitoring tools. 📌 Title: Observability with OpenTelemetry 🔗 URL: 🧩 Overview Enable with `CLAUDE_CODE_ENABLE_TELEMETRY=1` to export traces, metrics, and logs via OTLP to Honeycomb, Datadog, Grafana, Langfuse, and more. W3C trace context propagation automatically links agent traces to your application traces. 🛠 How to use it ```bash export CLAUDE_CODE_ENABLE_TELEMETRY=1 export CLAUDE_CODE_ENHANCED_TELEMETRY_BETA=1 export OTEL_EXPORTER_OTLP_ENDPOINT=https://your-collector:4318 ``` 🏗 Practical usage - Monitor "which tools were called, how long each took, how many tokens were used, and where failures occurred" in a single Datadog dashboard. - Get `claude_code.interaction` / `llm_request` / `tool` / `hook` spans with enhanced telemetry to visualize entire sub-agent delegation chains in one trace. - Inject ` / ` via `OTEL_RESOURCE_ATTRIBUTES` to build per-user audit trails and forward to SIEM. 💡 Use cases 🔍 Detailed trace analysis of agent execution 👥 Per-user audit trails 🚨 Bottleneck identification during failures ⚠️ Watch out The `console` exporter conflicts with the SDK's message channel — don't use it. For short-lived processes, shorten `OTEL_*_EXPORT_INTERVAL` to prevent missed flushes. #ClaudeAgentSDK# #AI#
