Enable agent

For gradle as an example

bootRun {
	jvmArgs = ["-Dskywalking.agent.service_name=gateway", "-javaagent:$projectDir/agent/skywalking-agent.jar"]
}

• skywalking.agent.service_name should be same as service name in application.yml to avoid some issues.

Run services

gradle :gateway:bootRun
gradle :demo-service:bootRun

import Demo.postman_collection.json into postman
