JMeter 在 CLI 中给出错误百分比，但在 GUI 中没有

Question

我在 docker 容器中有一个小型微服务运行ning，我试图获取使用 JMeter CLI 的延迟。我使用 JMeter GUI 进行了测试，运行首先进行了测试。然后错误百分比为 0。但是当我运行使用 CLI 进行相同的测试时，我得到了错误百分比的值。我收到以下警告：

这是我用来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ning 时，如何不显示错误百分比？

Answer 1

我没看到你从哪里得到 a value for error percentage 因为它似乎是零:

summary = 50 in 00:00:02 = 25.0/s Avg: 50 Min: 4 Max: 323 Err: 0 (0.00%)

如果您在生成的 /Users/sulekahelmini/Documents/fyp/fyp_work/MLscripts/agg_test.csv 中看到错误，则可能是该文件以前存在并且包含 "old" 结果失败。

此外，我认为您正在使用 Aggregate Report 侦听器向该文件写入一些内容，然后使用 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"clean"和有效结果：

删除 /Users/sulekahelmini/Documents/fyp/fyp_work/MLscripts/agg_test.csv 文件
删除 /Users/sulekahelmini/Documents/fyp/fyp_work/MLscripts/jmeter_results.jtl 文件
从您的测试计划中删除汇总报告侦听器（和所有其他侦听器）作为 listeners don't add any value and only consume resources
在终端中重复你的 2 个命令
您应该看到 agg_test.csv 文件没有任何错误
