Getting Started

Get up and running with Jaeger in your local environment

Version 1.26 Go to the latest 1.x version Go to the latest 2.x version

If you are new to distributed tracing, please check the Introduction page.

Instrumentation

Your applications must be instrumented before they can send tracing data to Jaeger backend. Check the Client Libraries section for information about how to use the OpenTracing API and how to initialize and configure Jaeger tracers.

All in One

All-in-one is an executable designed for quick local testing, launches the Jaeger UI, collector, query, and agent, with an in memory storage component.

The simplest way to start the all-in-one is to use the pre-built image published to DockerHub (a single command line).

docker run -d --name jaeger \
  -e COLLECTOR_ZIPKIN_HOST_PORT=:9411 \
  -p 5775:5775/udp \
  -p 6831:6831/udp \
  -p 6832:6832/udp \
  -p 5778:5778 \
  -p 16686:16686 \
  -p 14268:14268 \
  -p 14250:14250 \
  -p 9411:9411 \
  jaegertracing/all-in-one:1.26.0

Or run the jaeger-all-in-one(.exe) executable from the binary distribution archives:

jaeger-all-in-one --collector.zipkin.host-port=:9411

You can then navigate to http://localhost:16686 to access the Jaeger UI.

The container exposes the following ports:

Port	Protocol	Component	Function
5775	UDP	agent	accept `zipkin.thrift` over compact thrift protocol (deprecated, used by legacy clients only)
6831	UDP	agent	accept `jaeger.thrift` over compact thrift protocol
6832	UDP	agent	accept `jaeger.thrift` over binary thrift protocol
5778	HTTP	agent	serve configs
16686	HTTP	query	serve frontend
14268	HTTP	collector	accept `jaeger.thrift` directly from clients
14250	HTTP	collector	accept `model.proto`
9411	HTTP	collector	Zipkin compatible endpoint (optional)

Sample App: HotROD

HotROD (Rides on Demand) is a demo application that consists of several microservices and illustrates the use of the OpenTracing API . A tutorial / walkthrough is available in the blog post: Take OpenTracing for a HotROD ride .

It can be run standalone, but requires Jaeger backend to view the traces.

Features

Discover architecture of the whole system via data-driven dependency diagram.
View request timeline and errors; understand how the app works.
Find sources of latency and lack of concurrency.
Highly contextualized logging.
Use baggage propagation to:
- Diagnose inter-request contention (queueing).
- Attribute time spent in a service.
Use open source libraries with OpenTracing integration to get vendor-neutral instrumentation for free.

Prerequisites

You need Go toolchain installed on your machine to run from source (see go.mod file for required Go version).
Requires a running Jaeger backend to view the traces.

Running

From Source

mkdir -p $GOPATH/src/github.com/jaegertracing
cd $GOPATH/src/github.com/jaegertracing
git clone git@github.com:jaegertracing/jaeger.git jaeger
cd jaeger
go run ./examples/hotrod/main.go all

From docker

docker run --rm -it \
  --link jaeger \
  -p8080-8083:8080-8083 \
  -e JAEGER_AGENT_HOST="jaeger" \
  jaegertracing/example-hotrod:1.26.0 \
  all

From binary distribution

Run example-hotrod(.exe) executable from the binary distribution archives:

example-hotrod all

Then navigate to http://localhost:8080.

Migrating from Zipkin

Collector service exposes Zipkin compatible REST API /api/v1/spans which accepts both Thrift and JSON. Also there is /api/v2/spans for JSON and Proto. By default it’s disabled. It can be enabled with --collector.zipkin.host-port=:9411.

Zipkin Thrift IDL and Zipkin Proto IDL files can be found in jaegertracing/jaeger-idl repository. They’re compatible with openzipkin/zipkin-api Thrift and Proto .
