jmeter性能监控

1、下载插件：JMeterPlugins-Standard-1.4.0.zip , JMeterPlugins-Extras-1.4.0.zip，ServerAgent-2.2.3.zip；
2、JMeterPlugins-Standard-1.4.0.zip , JMeterPlugins-Extras-1.4.0.zip解压取jar包放到apache-jmeter-4.0\lib\ext目录下；
3、ServerAgent-2.2.1.zip解压放到被监控机器上，解压，启动：双击startAgent.bat；或运行 sh startAgent.sh
4、打开jmeter5.0，可选择插件jp@gc - PerfMon Metrics Collector和jp@gc - Transactions per Second，输入（被测机器IP/host）启动端口默认为4444
5、执行脚本
报错

结论：jmeter5.0不支持JMeterPlugins-Standard和JMeterPlugins-Extras插件
改为jmeter3.1,以上同样操作，执行脚本

结论：无法连接4444端口，检查是否开启此端口
解决：重启serverAgent服务，尝试用telnet连接，检测到无法连接后，尝试将4444端口加入防火墙

firewall-cmd --list-all-zones
firewall-cmd --zone=public --add-port=4444/tcp --permanent
firewall-cmd --reload

经过一系列操作后仍无法telnet通
尝试修改连接的端口号java -jar ./CMDRunner.jar --tool PerfMonAgent --udp-port 5567 --tcp-port 5567
此时仍无法连接
再次使用sh startAgent.sh
jmeter连接成功。。。。但是telnet仍然不成功。。。。。无解
