Scala 2.9 (JDK6 or JDK7) is required.
git clone https://github.com/twitter/zipkin.git && cd zipkin or
download Zipkin to your
preferred directory and unzip.
Run (in separate bash windows):
bin/collector bin/query bin/web
Now you can access the Zipkin UI at http://localhost:8080/
By default, Zipkin runs on SQLite because it doesn't require additional setup. However, Zipkin is typically used with other databases (most often Cassandra) in production. For a quickstart with Cassandra, see the Ubuntu Quickstart and Mac Quickstart guides. These will help you get a somewhat more advanced Zipkin installation running on a single machine so that you can experiment with it.
For larger deployments, Zipkin works with several other services, and you may want to apply additional configuration. Some of those services and configurations are described below.
The next step after installation is to collect trace data to view in Zipkin. To do this, you must interface with the collector daemon to record trace data. There are several libraries to make this easier to do in different environments. Twitter uses Finagle; external libraries (currently for Python, REST, node, and Java) are listed in the wiki; and there is also a Ruby gem and Ruby Thrift client.
The default Zipkin collector configuration is
zipkin-collector-service/config/collector-dev.scala and the default Zipkin
query configuration is
are set up to work with SQLite by default. To use Zipkin with a different SQL
database, we recommend changing those configurations as described in the
For NoSQL databases, you have a few options. To run Zipkin with Cassandra for
example, you can copy the Cassandra configuration into the default
configuration, change the
bin scripts to run the Cassandra configuration, or
run the full daemon commands that the
bin scripts are invoking:
bin/sbt 'project zipkin-collector-service' 'run -f zipkin-collector-service/config/collector-cassandra.scala' bin/sbt 'project zipkin-query-service' 'run -f zipkin-query-service/config/query-cassandra.scala'
bin/web script does not access the database so you do not need to change
Zipkin runs on SQLite by default to make it easier to test out of the box. Running Zipkin on SQLite requires no additional setup. However, in production, Zipkin is most commonly used with Cassandra for the collector's storage. There are also plugins for Redis, HBase, and other SQL databases.
cassandra-cli -host localhost -port 9160 -f zipkin-cassandra/src/schema/cassandra-schema.txt
Zipkin can use ZooKeeper for coordination. That's where we store the server side sample rate and register the servers.
Scribe is the logging framework we use at Twitter to transport the trace data. There are several other ways to tell Zipkin what trace data to collect; in particular, if you are just trying out Zipkin you can skip this step entirely and point the ZipkinTracer directly at the collector.
To use Scribe with Zipkin, you need to set up a network store that points to the Zipkin collector daemon. A Scribe store for Zipkin might look something like this:
<store> category=zipkin type=network remote_host=220.127.116.11 remote_port=9410 use_conn_pool=yes default_max_msg_before_reconnect=50000 allowable_delta_before_reconnect=12500 must_succeed=no </store>
If you don't want to hardcode the IP address of your collector there are a few
options. One is to use an internal DNS entry for the collectors so that you only
have one place to change the addresses when you add or remove collectors.
Alternatively, if you want to get all fancy you can use a
modified version of Scribe that
picks up the collectors via ZooKeeper. When each collector starts up it adds
itself to ZooKeeper and when a collector shuts down it is automatically
removed. The modified Scribe gets notified when the set of collectors change.
To use this mode you change
remote_host in the configuration to
zk://zookeeper-hostname:2181/scribe/zipkin or something similar.
We're hoping that others might add non-Scribe transports for the tracing data; there is no reason why Scribe has to be the only one.
The UI is a standard Rails 3 app.
bundle install && bundle exec rails server.
zipkin-tracer gem adds tracing to a Rails application through the use of a Rack Handler.
use ZipkinTracer::RackHandler run <YOUR_APPLICATION>
If the application's static assets are served through Rails, those requests will be traced.
