| JMeterPlugins插件可以监控到服务器的CPU/memory、IO、硬盘等信息，具体操作步骤如下：
1.下载JMeterPlugins插件： 分两部分： ServerAgent-2.2.1.zip （服务器监听） （本机jmeter插件部分） 2. 解压JMeterPlugins-Standard-1.3.0.zip，到 apache-jmeter-2.13\lib\ext 目录 
解压缩 ServerAgent-2.2.1.zip，到监控的linux服务器目录下 /opt/apache-jmeter-2.9/ServerAgent-2.2.1 j进入这个工具的bin目录启动ServerAgent，启动过程如下，端口是4444
[root@vm-10-154-156-238 ServerAgent-2.2.1]# sh startAgent.sh
INFO 2015-08-25 11:36:44.947 [kg.apc.p] (): Binding UDP to 4444
INFO 2015-08-25 11:36:45.953 [kg.apc.p] (): Binding TCP to 4444
INFO 2015-08-25 11:36:45.960 [kg.apc.p] (): JP@GC Agent v2.2.0 started 3.修改jmeter安装路径中：bin/jmeter.properties文件的以下行:（jmeterplugins 和thread有关系所以要修改配置文件） #如果没有把thread_count这个参数打开是不会记录到线程有关的信息的： jmeter.save.saveservice.thread_counts=true 4.启动JMeter就可以看到多了很多jp@gc开头的选项（windows下启动） 5.在linux下使用non gui模式的命令是：
./jmeter.sh -n -t testplan.jmx -l result.jtl
testplan.jmx就是测试计划文件，result.jtl就是结果文件，如果没有把thread_count这个参数打开是不会记录到线程有关的信息的：
<httpSample t="363" lt="363" ts="1301644667897" s="true" lb="http://localhost/" rc="200" rm="OK" tn="Thread Group 1-138" dt="text" by="7888" ng="200" na="200"/>
ng代表当前线程组中有多少活动线程
na代表整个测试中有多少活动线程
如果没有打开thread_count参数就不会有ng和na的值了。
顺带在说明一下别的参数的意思：
· t表示从请求开始到响应结束的时间
· lt表示整个的空闲时间
· ts表示访问的时刻
· s表示返回的结果true表示成功，false表示失败
· lb表示标题
· rc表示返回的响应码
· rm表示响应信息
· tn表示线程的名字“1-138”表示第1个线程组的第138个线程。
· dt表示响应的文件类型
· by表示请求和响应的字节数 6.在jmeter中添加各种监控图标 添加路径：线程组-》添加-》监控 
监控：jp@gc - PerfMon Metrics Collectot(cup/memory/io/硬盘等)

9.另外一个监控cpu的工具（连接远程进程，没有测试通过。。。本地连接可以用） 监控内存及CPU等（jconsole） 最近逛论坛的时候，发现了一个比较好的监控内存CPU等的小工具，本着开源小工具多多益善的原则，记录一下。 打开这个小工具的步骤很简单，如果你已经配置好了Jmeter运行的环境，那么你也就不用去做其他的配置，直接 点击：开始——》运行——》输入cmd——》然后在出现的命令行界面输入“jconsole”即可弹出一个【java监视和管理控制台】， 
将会弹出如下界面： 
这里我们选择本地进程，并点击一下sun.tools.jconsole.JConsole这一行，然后点击连接，就可以查看我们的内存和CPU的使用情况了。 当然，我们要得到服务器的内存使用等信息，也可以选择 本地进程下面的远程进程，在文本框中输入我们需要测试的服务器的IP地址：端口，然后在下面输入用户名和密码，点击连接，看看会出现什么情况。 
JMeter Properties 没有找到在那配置
- jmeterPlugin.perfmon.interval - metrics collection interval in milliseconds ---------- 指标收集时间间隔，单位是毫秒
- jmeterPlugin.perfmon.useUDP - true/false, enabling UDP connection try after failed TCP connection attempt--------值为 true 或 false，在 TCP 连接失败后是否尝试 UDP 连接
- jmeterPlugin.perfmon.label.useHostname - true/false, enable using "short" hostnames, default pattern is ([\w\-]+)\..*
- jmeterPlugin.perfmon.label.useHostname.pattern - string (escaped), regular expression to extract hostname (first group is matched)
- e.g. Default pattern would be: jmeterPlugin.perfmon.label.useHostname.pattern=([\w\-]+)\..*
- e.g. Pattern for EC2 us-east/west subdomain matching: jmeterPlugin.perfmon.label.useHostname.pattern=([\w\-]+\.us-(east|west)-[0-9]).*
- forcePerfmonFile - true/false, enabling it makes JMeter to write JTL file with perfmon metrics in the current directory
