Getting Started

Get up and running with Jaeger in your local environment


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. We recommend using the OpenTelemetryexternal link instrumentation and SDKs.

Historically, the Jaeger project supported its own SDKs (aka tracers, client libraries) that implemented the OpenTracing API. As of 2022, the Jaeger SDKs are no longer supported, and all users are advised to migrate to OpenTelemetry.

All in One

all-in-one is an executable designed for quick local testing. It includes the Jaeger UI, jaeger-collector, jaeger-query, and jaeger-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 --rm --name jaeger \
  -e COLLECTOR_ZIPKIN_HOST_PORT=:9411 \
  -p 6831:6831/udp \
  -p 6832:6832/udp \
  -p 5778:5778 \
  -p 16686:16686 \
  -p 4317:4317 \
  -p 4318:4318 \
  -p 14250:14250 \
  -p 14268:14268 \
  -p 14269:14269 \
  -p 9411:9411 \
  jaegertracing/all-in-one:1.57.0

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:

PortProtocolComponentFunction
6831UDPagentaccept jaeger.thrift over Thrift-compact protocol (used by most SDKs)
6832UDPagentaccept jaeger.thrift over Thrift-binary protocol (used by Node.js SDK)
5775UDPagent(deprecated) accept zipkin.thrift over compact Thrift protocol (used by legacy clients only)
5778HTTPagentserve configs (sampling, etc.)
16686HTTPqueryserve frontend
4317HTTPcollectoraccept OpenTelemetry Protocol (OTLP) over gRPC
4318HTTPcollectoraccept OpenTelemetry Protocol (OTLP) over HTTP
14268HTTPcollectoraccept jaeger.thrift directly from clients
14250HTTPcollectoraccept model.proto
9411HTTPcollectorZipkin compatible endpoint (optional)

Sample App: HotROD

HotROD (Rides on Demand) is a demo application that consists of several microservices and illustrates the use of OpenTelemetryexternal link and distributed tracing. A tutorial / walkthrough is available in the blog post: Take Jaeger for a HotROD rideexternal link .

The HotROD app 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) and time spent in a service.
  • Use open source libraries from opentelemetry-contrib to get vendor-neutral instrumentation for free.

Running

We recommend running Jaeger and HotROD together via docker compose.

With Docker Compose

git clone git@github.com:jaegertracing/jaeger.git jaeger
cd jaeger/examples/hotrod
docker compose up
# Ctrl-C to stop

With Docker

docker run --rm -it --link jaeger \
  -p8080-8083:8080-8083 \
  -e OTEL_EXPORTER_OTLP_ENDPOINT="http://jaeger:4318" \
  jaegertracing/example-hotrod:1.57.0 \
  all --otel-exporter=otlp

From Source

In order to run from source you need:

git clone git@github.com:jaegertracing/jaeger.git jaeger
cd jaeger
go run ./examples/hotrod/main.go 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

jaeger-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 Thriftexternal link IDL and Zipkin Protoexternal link IDL files can be found in jaegertracing/jaeger-idlexternal link repository. They’re compatible with openzipkin/zipkin-apiexternal link Thriftexternal link and Protoexternal link .
