Zipkin (doc/zipkin-logo-200x119.jpg)

Zipkin is a distributed tracing system. It is used by Twitter to help gather timing data for all their disparate services. The front end is a "waterfall" style graph of service calls showing call durations as horizontal bars:

Running Zipkin

Zipkin is a collection of processes (a backend for the data, a "collector", and query engine, and a web UI) and all of them need to be running to make any progress:

Architecture

If you are familiar with Docker, the quickest way to get started quickly is to use the Docker Zipkin project, which (in addition to being able to build docker images) provides scripts and a docker-compose.yml for launching pre-built images, e.g.

$ git clone https://github.com/openzipkin/docker-zipkin
$ cd docker-zipkin/deploy
$ docker-compose up

If you are happy building from source you can use the scripts in the [bin/] directory of this repository.

Here's how to start zipkin using the default file-based backend and view traces.

# get the zipkin source and change to its directory
$ git clone https://github.com/openzipkin/zipkin; cd zipkin
# start the collector server in a new terminal session or tab
$ ./bin/collector
# start the query server in a new terminal session or tab
$ ./bin/query
# start the web server in a new terminal session or tab
$ ./bin/web
# create dummy traces
$ ./bin/tracegen
# open the ui and look at them!
$ open http://localhost:8080/
