这两天看了好几篇帖子,写zipkin与dubbo整合的内容都不全面,忍不住亲自上手码一遍。
利用zipkin可以对dubbo进行调用链监控,可以查到调用链中的dubbo服务的性能,并且dubbo提供了SPI的接口,能很容易完成并自定义相应的filter去监控dubbo服务。
ZipKin介绍
Zipkin是一个致力于收集分布式服务的时间数据的分布式跟踪系统。
Zipkin 主要涉及四个组件:collector(数据采集),storage(数据存储),search(数据查询),UI(数据展示)。
github源码地址:https://github.com/openzipkin/zipkin。
Zipkin提供了可插拔数据存储方式:In-Memory,MySql, Cassandra, Elasticsearch
ZipKin部署与运行 (注意需要在linux下运行,JDK1.8)
1、下载zipkin
http://central.maven.org/maven2/io/zipkin/java/zipkin-server/2.11.7/zipkin-server-2.11.7-exec.jar
2、运行zipkin
(1)In-Memory方式
nohup java -jar zipkin-server-2.11.7-exec.jar &
注意:内存存储,zipkin重启后数据会丢失,建议测试环境使用
(2)MySql方式
目前只与MySQL的5.6-7。它的设计是易于理解,使用简单。但是,当数据量大时,查询很慢。性能不是很好。
创建数据库zipkin
建表

启动zipkin命令
STORAGE_TYPE=mysql MYSQL_HOST=IP MYSQL_TCP_PORT=3306 MYSQL_DB=zipkin MYSQL_USER=username MYSQL_PASS=password nohup java -jar zipkin-server-2.11.7-exec.jar &
(3)Elasticsearch方式
创建elasticsearch用户,安装启动Elasticsearch服务
官方文档:https://www.elastic.co/guide/en/elasticsearch/reference/current/index.html
zipkin启动命令
STORAGE_TYPE=elasticsearch ES_HOSTS=http://IP:9200 nohup java -jar zipkin-server-2.11.7-exec.jar &启动成功访问地址:http://192.168.20.15:9411/zipkin/(192.168.20.15替换为对应zipkin部署服务器地址)
