Tracing applications with sleuth, zipkin, elasticsearch and kibana

Tracing applications

This example is a simple guide to start with tracing yours applications.

Sleuth

It's a library which allows to follow a request or action. Only need to add the dependency en your pom:

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-sleuth</artifactId>
</dependency>

set up some properties in application.yml:

spring:
  sleuth:
    sampler:
      probability: 1.0

When you run your application, you can watch a trace_id, span_id and follow your action.

Zipkin

It's a library, which stores all traces from your applications. Only need to add the dependency en your pom:

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-zipkin</artifactId>
</dependency>

set up some properties in application.yml:

spring:
  #zipkin:
      # Uncomment to send to zipkin, replacing 192.168.99.100 with your zipkin IP address
      # baseUrl: http://192.168.99.100:9411/
sample:
  zipkin:
    # When enabled=false, traces log to the console. Comment to send to zipkin
    enabled: false

Download zipkin from his site. By default zipkin stores messages in memory, but you can change this behavior starting for example with elasticsearch as storage:

STORAGE_TYPE=elasticsearch ES_HOSTS=URL_TO_ES java -jar zipkin.jar

Elasticsearch

It's a data store NRT. You can download from his site. By default you can query to elastisearch in port 9200. Execute the process "bin/elasticsearch".

Kibana

It's a data visualizer that is connected with elasticsearch. You can download from his site. By default you can query to kibana in port 5601. You need to change his configuration file "config/kibana.yml" for correct working of kibana:

# The URL of the Elasticsearch instance to use for all your queries.
elasticsearch.url: "http://HOST_ES:PORT_ES"

Execute the process "bin/kibana".
