BusyBee demo app

A minimal web app showcasing BusyBee: a background job queue with OpenTelemetry, Swagger, Prometheus metrics, and Seq for centralized logging and tracing.

Quick start (Docker Compose)

Requirements: Docker + Docker Compose.

cd examples/DemoApp
docker compose up -d --build

Stop and clean up:

docker compose down -v

Services and URLs

• Demo API: http://localhost:8100
  • Swagger UI: http://localhost:8100/swagger
  • Prometheus metrics: http://localhost:8100/metrics
• Seq (logs & tracing): http://localhost:8200
  • The app exports OTLP logs and traces to Seq.
• Prometheus (metrics): http://localhost:8300
  • Scrapes the app’s /metrics endpoint (see prometheus.yml).

API examples

• Enqueue a job (POST /queue):

curl -X POST http://localhost:8100/queue

Response contains the JobId; the job runs asynchronously. Logs and traces are sent to Seq. Jobs may fail or timeout randomly to demonstrate error handling.

• Get aggregated execution log (GET /queue):

curl http://localhost:8100/queue

Returns a grouped log of job events ordered by enqueue and event timestamps.

• Cancel a job (POST /job/{jobId}/cancel):

curl -X POST http://localhost:8100/job/{jobId}/cancel
