JMeter-根据线程数动态增加 [英] JMeter - dynamic ramp up according to threads number

问题描述

我想用属性中的线程号执行JMeter，该线程号可以是10-1000，并设置最佳的启动周期.

I want to execute JMeter with thread number in property, that can be 10-1000 and set the optimal ramp up period.

在 JMeter 中，建议从线程数开始:

In JMeter it's suggested to start with number of threads:

以Ramp-up =线程数开始，并根据需要向上或向下调整.

Start with Ramp-up = number of threads and adjust up or down as needed.

但是在我的服务器中，在这种配置下它不能很好地工作，我需要的线程数是两倍以上.

But in my servers it's not working well in this configuration and I need more than double the thread number.

我可以使用公式作为线程号(属性值)* 2.5来设置加速吗?还是应该为此目的在每个线程的开始处添加一个Timer?

Can I set the ramp up using a formula as thread Number (property value) * 2.5? or maybe should I add a Timer a the start of each thread for this purpose?

当前，如果我将2*2.5置于加速期，则将其视为0

Currently if I put 2*2.5 in Ramp-Up period it consider it as 0

INFO o.a.j.t.ThreadGroup:正在启动线程组... number = 1线程= 2加速= 0 perThread = 0.0 delayStart = false

INFO o.a.j.t.ThreadGroup: Starting thread group... number=1 threads=2 ramp-up=0 perThread=0.0 delayedStart=false

我更喜欢JMeter vanilla中没有插件的解决方案.

I prefer solution in JMeter vanilla without plugins.

推荐答案

您可以使用 __groovy 函数以使用属性值:

You can use __groovy function to use property value:

${__groovy(2.5*props.get("rampup").toInteger()),)}

__ groovy函数评估传递给它的Apache Groovy脚本，并返回结果.

The __groovy function evaluates Apache Groovy scripts passed to it, and returns the result.

道具-JMeterProperties(类java.util.Properties)对象

props - JMeterProperties (class java.util.Properties) object
