Distributed Tracing

Demonstrates how to enable OpenTelemetry distributed tracing with the Azure Managed Durable Task Scheduler (DTS). Traces are exported to a local Jaeger or OTLP-compatible collector so you can visualize the full orchestration lifecycle.

Features Covered

Feature API
OpenTelemetry setup NodeSDK, OTLPTraceExporter, SimpleSpanProcessor
Builder pattern DurableTaskAzureManagedClientBuilder, DurableTaskAzureManagedWorkerBuilder
Data pipeline Fan-out/fan-in with chained activities
Console logger ConsoleLogger

Prerequisites

  • Node.js ≥ 22
  • Docker (for the DTS Emulator and Jaeger)

Setup

# From the repository root
cd examples/azure-managed
docker compose up -d          # start DTS emulator (and Jaeger if configured)
cp .env.emulator .env         # configure for local emulator
cd ../..
npm install && npm run build

Run

npm run example -- ./examples/azure-managed/distributed-tracing/index.ts

After the orchestrations complete, open the Jaeger UI at http://localhost:16686 and search for service durabletask-js-tracing-example to view traces.

Running Against Azure

See the parent README for instructions on running against a real Azure Managed DTS resource.
