如何从JMeter摘要中排除预热时间? [英] How to exclude warmup time from JMeter summary?
问题描述
我有一个简单的JMeter吞吐量测试，该测试会产生20个线程，并且每个线程都会对数据库执行一个简单的SQL查询.我将启动时间设置为10秒，总测试时间为70秒.
I have a simple JMeter throughput test that spawns 20 threads and each thread executes a simple SQL query against a database. I have set a ramp up time of 10 seconds and a total test time of 70 seconds.
当我在非GUI模式下执行测试时，我看到以下摘要输出:
When I execute the test in non-GUI mode I see the following summary output:
summary + 1 in 0.1s = 7.4/s Avg: 135 Min: 135 Max: 135 Err: 0 (0.00%) Active: 1 Started: 1 Finished: 0
summary + 137501 in 28.5s = 4831.0/s Avg: 3 Min: 1 Max: 614 Err: 0 (0.00%) Active: 20 Started: 20 Finished: 0
summary = 137502 in 29s = 4796.9/s Avg: 3 Min: 1 Max: 614 Err: 0 (0.00%)
summary + 171000 in 30s = 5703.8/s Avg: 3 Min: 1 Max: 519 Err: 0 (0.00%) Active: 20 Started: 20 Finished: 0
summary = 308502 in 59s = 5260.8/s Avg: 3 Min: 1 Max: 614 Err: 0 (0.00%)
summary + 61016 in 11.5s = 5309.0/s Avg: 3 Min: 1 Max: 518 Err: 0 (0.00%) Active: 0 Started: 20 Finished: 20
summary = 369518 in 70.1s = 5268.9/s Avg: 3 Min: 1 Max: 614 Err: 0 (0.00%)
如您所见，吞吐量在开始的30秒内很低，但随后又有所提高.我知道这可能是由于线程启动和其他系统组件预热所致.
As you can see that the throughput is low in the first 30 seconds but picks up later. I understand that this could be due to the threads starting and other system components warming up.
有没有一种方法可以从最终计算中排除价值"X"秒的起始数字.我使用了一些自定义性能测试，在测试输出之前，我总是排除前"X"秒，直到系统达到稳定状态为止.
Is there a way I can exclude "X" seconds worth of starting numbers from the final calculation. I have used some custom performance tests where I always excluded the first "X" seconds until the system reached a steady state before measuring the output.
反正我可以在JMeter中做到吗?
Is there anyway I can do that in JMeter?
推荐答案
您可以使用jmeter-plugins生成图形
You can use jmeter-plugins to generate graphs
并填写起始偏移量字段.
And fill in start offset field.
