jmeter压测学习25-监听器之服务器性能指标监控(PerfMon Metrics Collector)

前言

我们做性能测试的时候，不仅要关注jmter上的测出来的TPS值和响应时间等指标，还得关注服务器的性能指标。
服务器上性能指标如何监控呢，可以安装PerfMon服务器代理来监控

PerfMon服务器代理

PerfMon服务器代理的github地址https://github.com/undera/perfmon-agent,可以下载到安装包

ServerAgent-2.2.3.zip下载地址 https://github.com/undera/perfmon-agent/releases/download/2.2.3/ServerAgent-2.2.3.zip

下载完成后，上传到我们压测环境的服务器上，新建一个PerfMon文件夹，把安装包放到PerfMon目录
可以在windows上下载了上传到服务器上，也可以直接在服务器上wget下载

wget https://github.com/undera/perfmon-agent/releases/download/2.2.3/ServerAgent-2.2.3.zip
下载后解压文件

[root@VM_0_2_centos ~]# mkdir Perfmon
[root@VM_0_2_centos ~]# cd Perfmon/
[root@VM_0_2_centos Perfmon]# wget https://github.com/undera/perfmon-agent/releases/download/2.2.3/ServerAgent-2.2.3.zip
[root@VM_0_2_centos Perfmon]# unzip ServerAgent-2.2.3.zip 
[root@VM_0_2_centos Perfmon]# cd ServerAgent-2.2.3/
[root@VM_0_2_centos ServerAgent-2.2.3]# ll

执行./startAgent.sh 启动服务，当看到如下提示，说明启动成功

[root@VM_0_2_centos ServerAgent-2.2.3]# ./startAgent.sh
INFO    2020-12-24 23:03:42.523 [kg.apc.p] (): Binding UDP to 4444
INFO    2020-12-24 23:03:43.602 [kg.apc.p] (): Binding TCP to 4444
INFO    2020-12-24 23:03:43.624 [kg.apc.p] (): JP@GC Agent v2.2.3 started

默认监听的UDP和TCP端口是4444，服务正常启动后，在自己windows本地用telnet端口能不能连得通

telnet ip 4444

我自己本地的windows电脑一直连不上这个4444端口，不知道为啥

如果4444端口连不上，可以换个端口重新启动,带上-udp-port 和 --tcp-port两个参数

[root@VM_0_2_centos ServerAgent-2.2.3]# ./startAgent.sh  --udp-port 3456 --tcp-port 3456
INFO    2020-12-24 23:32:11.661 [kg.apc.p] (): Binding UDP to 3456
INFO    2020-12-24 23:32:12.696 [kg.apc.p] (): Binding TCP to 3456
INFO    2020-12-24 23:32:12.709 [kg.apc.p] (): JP@GC Agent v2.2.3 started

再重新telnet ip 3456 端口就能连上了
