系统配置文件：

application.properties

server.port=8981
spring.application.name=zipkin2client
spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
spring.zipkin.rabbitmq.queue=zipkin
spring.sleuth.sampler.probability=1.0

后记

本章采用zipkin2.9.4与spring boot 2.1.0.BUILD-SNAPSHOT集成。消息通道由默认的http协议更换为rabbitmq，解决高性能和高并发问题。因为是测试环境，采用内存存储。生产环境建议更换为elasticsearch存储。

客户端采集只记录了服务间调用的性能数据采集，sql、方法间调用的性能数据没有收集。测试采样率为1.0，即为全量采集，能够修改spring.sleuth.sampler.probability参数，默认为0.1。生产环境不建议开启全量采集。

曾经在生产环境部署apm工具，一个应用集群一天采集64g日志数据，这个数据量较大，对服务器带宽会形成极大冲击，在生产环境使用须要合理考虑组网问题。
