Overview

OpenTelemetry gRPC Instrumentation allows the user to automatically collect trace data and export them to the backend of choice (we can use Zipkin or Jaeger for this example), to give observability to distributed systems.

Installation

# from this directory
npm install

Setup Zipkin Tracing or Setup Jaeger Tracing

Run the Application

Zipkin

• Run the server

  # from this directory
  npm run zipkin:server

• Run the client

  # from this directory
  npm run zipkin:client

Zipkin UI

zipkin:server script should output the traceid in the terminal (e.g traceid: 4815c3d576d930189725f1f1d1bdfcc6). Go to Zipkin with your browser http://localhost:9411/zipkin/traces/(your-trace-id) (e.g http://localhost:9411/zipkin/traces/4815c3d576d930189725f1f1d1bdfcc6)

Jaeger

• Run the server

  # from this directory
  npm run jaeger:server

• Run the client

  # from this directory
  npm run jaeger:client

Jaeger UI

jaeger:server script should output the traceid in the terminal (e.g traceid: 4815c3d576d930189725f1f1d1bdfcc6). Go to Jaeger with your browser http://localhost:50051/trace/(your-trace-id) (e.g http://localhost:50051/trace/4815c3d576d930189725f1f1d1bdfcc6)
