opentelemetry-js/examples/opentracing-shim

Overview

OpenTracing shim allows existing OpenTracing instrumentation to report to OpenTelemetry.

This is a simple example that demonstrates how existing OpenTracing instrumentation can be integrated with OpenTelemetry.

The example shows key aspects of tracing such as

• Root Span (on client)
• Child Span from a remote parent (on server)
• Span Tag
• Span Log
• Make a shim between OpenTracing and OpenTelemetry tracers

Installation

# from this directory
$ npm install

Run the Application

Zipkin

• Setup Zipkin Tracing UI

• Run the server

# from this directory
$ npm run zipkin:server

• Run the client

# from this directory
$ npm run zipkin:client

• Check trace

  zipkin:client should output the traceId in the terminal.

  Go to Zipkin with your browser http://localhost:9411/zipkin/traces/(your-trace-id) (e.g http://localhost:9411/zipkin/traces/4815c3d576d930189725f1f1d1bdfcc6)

Jaeger

• Setup Jaeger Tracing UI

• Run the server

# from this directory
$ npm run jaeger:server

• Run the client

# from this directory
$ npm run jaeger:client

• Check trace

  jaeger:client should output the traceId in the terminal.

  Go to Jaeger with your browser http://localhost:16686/trace/(your-trace-id) (e.g http://localhost:16686/trace/4815c3d576d930189725f1f1d1bdfcc6)
