jmeter 在 ubuntu 上执行 ftp 协议脚本时总是报错

用 ubuntu 上 apt-get update 后安装的 apt install jmeter， 版本时 Version 2.13.20170723。执行 基于 ftp 协议的脚本时报错空指针

用上传的 5.1.1 的 jmeter 包，虽然不退出，但是很快就 tyding up, 然后退出，其实也是问题。

最后 stackoverflow 上看到，需要安装一个包来支持 jmeter 的 ftp 协议脚本

apt install jmeter-ftp


完美解决。

jmeter 3.0版本以上就提供了图形化的html报告了，运行完成之后，执行命令:
jmeter -g test.jtl -o resultreport  生成html报告

参数： 
-g : result.jtl 已经存在的.jtl文件的路径。 
-o ：用于存放html报告的目录 
然后resultreport  就是生成的报告文件夹，下载下来查看分析吧；
