一、问题定位
1、jmeter中通过PerfMon Metrics Collector插件监控CPU和内存等等显示ConnectException连接超时
2、定位到是因为服务器端没有启动serverAgent.sh代理，启动发现4444端口已经被占用，通过ps -ef|grep 关键字，找到进程kill掉，然后通过
cd /root/ServerAgent-2.2.1/
chmod +x startAgent.sh
touch nohup.out
nohup ./startAgent.sh nohup.out & ==》后台启动
netstat -ntlp
ps -ef | grep Agent
tail -f /root/ServerAgent-2.2.3/nohup.out
