Springcloud 集成 Skywalking 实现全链路追踪

下载链接
https://skywalking.apache.org/downloads/

本地搭建springcloud工程，偷懒可参考gitee
https://gitee.com/wangLi1997/spring-cloud-example.git

解压skywalking

准备工作

1.修改application.yml，指定es地址

2.修改端口，默认8080改成其他端口

3.修改 agent.config

# Backend service addresses.
collector.backend_service=${SW_AGENT_COLLECTOR_BACKEND_SERVICES:127.0.0.1:11800}

plugin.toolkit.log.grpc.reporter.server_host=${SW_GRPC_LOG_SERVER_HOST:127.0.0.1}
plugin.toolkit.log.grpc.reporter.server_port=${SW_GRPC_LOG_SERVER_PORT:11800}
plugin.toolkit.log.grpc.reporter.max_message_size=${SW_GRPC_LOG_MAX_MESSAGE_SIZE:10485760}
plugin.toolkit.log.grpc.reporter.upstream_timeout=${SW_GRPC_LOG_GRPC_UPSTREAM_TIMEOUT:30}

4.如果有用到spring-gateway，需要手动调整

copy到

修改idea配置

-javaagent:E:\gitee\apache-skywalking-apm-8.6.0\apache-skywalking-apm-bin\agent\skywalking-agent.jar
-Dskywalking.agent.service_name=你的微服务名
-Dskywalking.collector.backend_service=127.0.0.1:11800

启动Skywalking

启动springcloud项目

完成几次多模块服务调用

如果没有数据，可以调整下时间

集成logback
