I have one java application . then run 'java -javaagent:/usr/local/src/agent/skywalking-agent.jar -jar /usr/local/src/server.jar'(agent.config agent.service_name=server), the instance is server-pid:11815@localhost;after restart ,the instance is server-pid:12114@localhost.I think they are the same application,I should have seen a continuous record, not two...Did I overlook anything?So what should I do?
