Java Agent配置方式

java -javaagent:/opt/skywalking/apache-skywalking-apm-bin/agent/skywalking-agent.jar -Dskywalking.agent.service_name=skywalkingdemo3  -Dskywalking.collector.backend_service=192.168.1.11:11800 -jar SkywalkingDemo-0.0.1-SNAPSHOT.jar

skywalking集成docker
准备工作

新建自定义镜像目录 mkdir -p /data/skywalking
将SkywalkingDemo-0.0.1-SNAPSHOT.jar复制到/data/skywalking目录中 cp
/data/SkywalkingDemo-0.0.1-SNAPSHOT.jar /data/skywalking/

配置agent

将agent目录复制到/data/skywalking备用 cp -r
/opt/skywalking/apache-skywalking-apm-bin/agent /data/skywalking
