JMeter使用记录3 -- 性能监控插件jmeter-plugins

JMeter生成的result图表实在是不容易看，一直用着一款插件，可以生成许多更直观的图，甚至可以结合server-agent查看系统的运行资源使用情况。

JMeter测试数据图表生成

插件安装

1. 下载最新jmeter插件jmeter-plugins-standard downloads page

2. 把zip文件夹解压到Jmeter的安装目录

3. 修改jmeter安装路径中：bin/jmeter.properties文件的以下行:

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

获取jtl文件

在Thread Groups里面新建View Results Tree，把results写到jtl文件，点击configure可以选择要分析的数据

从jtl文件中生成性能报表

JMeter-plugins可以从jtl里面提取数据生成各种类型的图表，在我们的系统中最关注的就是系统延迟和TPS，可以通过CMDRunner来生成对应的图表。

java -jar apache-jmeter-2.8/lib/ext/CMDRunner.jar --tool Reporter --input-jtl ./testresult.jtl --plugin-type LatenciesOverTime --generate-png report-latency.png
java -jar apache-jmeter-2.8/lib/ext/CMDRunner.jar --tool Reporter --input-jtl ~/testresult.jtl --plugin-type TransactionsPerSecond --generate-png report-transactionPerSec.png

服务器资源使用监控

上面说的是在JMeter测试端测试服务器的吞吐，实际测试过程中我们也需要观察服务器的资源使用情况，这个可以通过ServerAgent来实现。ServerAgent在每个服务器上启动一个进程监听服务器数据，并且提供4444端口给外部读取监听数据，JMeter Plugin提供了读取ServerAgent数据的插件。

Cluster

Agent安装启动在http://jmeter-plugins.org/downloads/all/下载Serveragent，解压后运行startAgent.bat(windows), startAgent.sh(linux)，系统监听4444端口。

JMeter根据结果生成统计图
同样通过JMeter-plugins可以从jtl里面提取数据生成对应的图表

java -jar $jmeter_path/lib/ext/CMDRunner.jar --tool Reporter --input-jtl cpu.jtl --plugin-type PerfMon --generate-png report-cpu.png >& /dev/null
java -jar $jmeter_path/lib/ext/CMDRunner.jar --tool Reporter --input-jtl memory.jtl --plugin-type PerfMon --generate-png report-memory.png >& /dev/null
java -jar $jmeter_path/lib/ext/CMDRunner.jar --tool Reporter --input-jtl diskIO.jtl --plugin-type PerfMon --generate-png report-diskIO.png >& /dev/null

PS：

1. 以前服务器监控各自为政，现在有很多非常优秀的软件，提供统一接口监控系统使用情况，监控整个大的局域网系统情况，例如：nagios。

2. 生成图的操作可以通过jmeter来实现，有一款jmeter插件可以执行ssh command http://code.google.com/p/jmeter-ssh-sampler/
