JMeter CLI报告生成失败-org.apache.jmeter.report.dashboard.GenerationException：数据导出器“ json”

编程问答 2022-08-14

问题描述

JMeter 5.3

我使用CLI如下：

C:\Users\guyl\OneDrive - xxxxLTD\Guy\apache-jmeter-5.3\bin>jmeter -n -t "C:\Users\guyl\OneDrive - xxxxLTD\Guy\JMeter\DCS DB threaded test.jmx"  -l"C:\Users\guyl\OneDrive - xxxxLTD\Guy\JMeter\db_report.csv" -Jthreads=5 -Jloops=100 -e -o"C:\Users\guyl\OneDrive - xxxxLTD\Guy\JMeter\output\19082020\"

Error generating the report: org.apache.jmeter.report.dashboard.GenerationException: Data exporter "json" is unable to export data.
... end of run

最后，您可以看到我们拥有：

Error generating the report: org.apache.jmeter.report.dashboard.GenerationException: Data exporter "json" is unable to export data.
... end of run

请注意，报告的扩展名是CSV还是JTL都没关系。

我 能够生成JTL报告，然后运行jmeter -g <my JTL file>，但是我想使用-e选项。

更新：现在，我在使用g选项时遇到了错误：

C:\Users\guyl\OneDrive - xxxLTD\Guy\apache-jmeter-5.3\bin>jmeter -g "C:\Users\guyl\OneDrive - xxxLTD\Guy\JMeter\db_report" -o"C:\Users\guyl\OneDrive - xxxLTD\Guy\JMeter\output\19082020\"
An error occurred: Data exporter "json" is unable to export data.
errorlevel=1
Press any key to continue . . .

这是我在jmeter.log文件中找到的内容：

所以这一切都始于：

Caused by: java.io.IOException: Unable to create directory C:\Users\guyl\OneDrive - xxx LTD\Guy\JMeter\output\19082020"

应该创建该文件夹（如果不存在），不是吗？

解决方法

JMeter将仅创建1级文件夹，而不是整个层次结构。

第二，尝试避免在其中放置空格的文件夹。
