JMeter在CLI中提供错误百分比，但在GUI中不提供

Question

我在docker容器中运行了一个小型微服务，试图获取使用JMeter CLI的延迟。我使用JMeter GUI进行了测试，然后首先从中运行了测试。然后错误百分比为0。但是当我使用CLI运行相同的测试时，我得到一个错误百分比值。我收到以下警告：

这是我用于运行测试并将结果转换为csv的代码：

#run test
  cd /Users/sulekahelmini/Documents/fyp/apache-jmeter-5.2.1/bin && sh jmeter -n -t /Users/sulekahelmini/Documents/fyp/jmeter_scripts/factorial.jmx -l /Users/sulekahelmini/Documents/fyp/fyp_work/MLscripts/jmeter_results.jtl
  #convert result to csv
  cd /Users/sulekahelmini/Documents/fyp/apache-jmeter-5.2.1/bin && ./JMeterPluginsCMD.sh --generate-csv /Users/sulekahelmini/Documents/fyp/fyp_work/MLscripts/agg_test.csv --input-jtl /Users/sulekahelmini/Documents/fyp/fyp_work/MLscripts/jmeter_results.jtl --plugin-type AggregateReport

下面显示的是生成的汇总报告（使用jtl文件）。请注意，那里有一个错误百分比。

[另外，请注意，我的JMeter不在容器内。我在这里做错了什么？在GUI中运行时如何获得错误百分比？

Answer 1

我似乎看不到a value for error percentage，因为它似乎是零，所以从哪里得到它：

摘要= 0 in 00:00:02 = 25.0 / s平均：50最小值：4最大值：323 错误：0（0.00％）

如果在生成的/Users/sulekahelmini/Documents/fyp/fyp_work/MLscripts/agg_test.csv中看到错误，则可能是文件先前存在并且包含带有失败的“旧”结果的情况。

[此外，我认为您正在使用Aggregate Report侦听器向该文件中写入内容，稍后使用JMeter插件命令行工具将最后的结果附加到同一文件中。

为了获得“干净的”和有效的结果：

1. 删除/Users/sulekahelmini/Documents/fyp/fyp_work/MLscripts/agg_test.csv文件
2. 删除/Users/sulekahelmini/Documents/fyp/fyp_work/MLscripts/jmeter_results.jtl文件
3. 将测试报告中的聚合报告侦听器（和所有其他侦听器）从listeners don't add any value and only consume resources中删除
4. 在终端中重复您的2条命令
5. 您应该看到agg_test.csv文件没有任何错误
