Jmeter Random Variable配置项可以为每个线程生成随机变量

Variable Name:     uuid
Output Format:     12345678-1234-4444-a123-000000000000
Minimum Value:     111111111111
Maximum Value:     999999999999
Seed for Random function：${__Random(1,10,)} //如果指定为一个固定值，则每次迭代，各个线程得到的随机值都会相同

Per Thread (User): True　　//每个线程生成一个随机数

iteration: 1
    thread: 1
        sampler 1: VALUE_1-1
        sampler 2: VALUE_1-1
        ...
    thread: 2
        sampler 1: VALUE_2-1
        sampler 2: VALUE_2-1
        ...
    ...
iteration: 2
    thread: 1
        sampler 1: VALUE_1-2
        sampler 2: VALUE_1-2
        ...
    thread: 2
        sampler 1: VALUE_2-2
        sampler 2: VALUE_2-2
        ...
    ...
