Add OpenTelemetry Tracing to Your App with Claude

OpenTelemetry has great docs but a steep setup curve — SDK init, auto-instrumentation packages, exporter config, span naming conventions. Claude knows all of this and can wire it up in one session.

Add OpenTelemetry tracing to this Express.js API. Instrument all HTTP routes,
database queries via Knex, and outbound HTTP calls via axios.
Export traces to an OTLP endpoint configured via environment variables.
Use meaningful span names and add custom attributes for user ID and tenant ID.

Claude picks the right auto-instrumentation packages for your stack, sets up the tracer provider correctly, and adds custom spans for business-critical operations you want to measure. It also knows to propagate trace context across service boundaries via W3C TraceContext headers.

# Laravel / PHP
Add OpenTelemetry tracing to this Laravel app using the open-telemetry/opentelemetry-php SDK.
Instrument Eloquent queries, Redis calls, and outbound Guzzle requests.
Export to a Jaeger collector at OTEL_EXPORTER_OTLP_ENDPOINT.

# Python / FastAPI
Instrument this FastAPI application with OpenTelemetry.
Use opentelemetry-instrumentation-fastapi and opentelemetry-instrumentation-sqlalchemy.
Add a custom span for the payment processing flow in app/services/payments.py.

Observability is the difference between guessing and knowing — let Claude set it up in one session.
