FRIEZA

简介

Frieza是一个jmeter分布式工具的加强版,更有效的控制jmeter的分布式执行效果

### 相较于jmeter分布式启动方式的优势

• Frieza知道各个slave所处的运行状态
• Frieza会对java环境进行检测，并尝试安装jdk1.8,当安装失败后会停止运行
• Frieza无需修改master或slave的properties中的server.rmi.ssl.disable,remote_hosts 等参数（运行jmeter命令时也无需指定-R参数）
• Frieza具有更强的控制slave负载机的运行与停止的能力，避免master停止，但是slave仍在运行的情况，避免部分slave异常导致无法启动分布式命令
• Frieza自动检查jmeter脚本中的results相关模块是否已经被禁用(打开result tree会对性能结果有较大的影响)

配置与启动方式

1.将Frieza工具放置到jmeter的bin目录下
2.赋予工具可执行权限

chmod +x Frieza

3.启动Frieza-master

./Frieza -M

4.启动Frieza-slave

./Frieza -R=192.168.0.3     (IP是master机的ip)

5.查看命令帮助文档

./Frieza -h

  -M    default slave server
  -R    string master host
  -v    version

Frieza-master交互式命令

• slave
  查看所有连接成功的slave的运行状态

    Starting        // 启动中 
    Idle            // 空闲状态
    Running         // 运行中
    Stopped         // 停止状态
    Failed          // 启动失败

    Frieze>>> slave
    nums    Ip              status
    1       192.168.31.1    Starting
    2       192.168.31.2    Idle
    3       192.168.31.3    Idle
    4       192.168.31.4    Idle

• jmeter
  与jmeter命令行执行方式一样，命令会自动添加slave中status处于Idle状态的设备

    Frieze>>> jmeter -n -t demo.jmx

• log
  读取jmeter.log文件的内容（查看jmeter压测数据，jmeter运行日志）

    Frieze>>> log
    ...

    ...

• stop
  停止所有 status = Running的slave,使其停止运行并恢复到Idle状态

    Frieze>>> stop

TODO

1. 更多系统支持
2. 自动根据现有的设备情况自动配置slave的JVM
3. 根据csv或txt文件以及目前slave的数量自动分发测试数据到各个slave的指定目录中
4. 检测并提示master和slave中的jmeter版本是否匹配
