java.lang.NumberFormatException在JMeter控制台日志上

Question

当我试图浏览JTL文件到聚合报告时，我在控制台日志上得到了java.lang.NumberFormatException。3个POST API的加载运行时间为2小时。我目前正在使用JMeter 5.4.3，这造成了字面上的痛苦。我无法分析这份报告。PFB附上完整的原木：

Answer 1

1654269947015是一个时间戳，可转换为2022年6月3日星期五下午格林尼治时间下午3:25:47.015。你所拥有的是"81654269947015"和"8"，在开始的时候，这里似乎错了。搜索您的JTL文件并移除前面的"8"，保存该文件并尝试再次向报表提供信息。

Answer 2

很可能你的.jtl结果文件在某个地方是腐败的

在结果文件的40654行中，JMeter试图将81654269947015解析为活动线程的数量，并且由于它比Integer的最大值要大，因此不适合于整数型

如果40654行是文件的最后一行，请使用您喜欢的文本编辑器手动删除它。

JMeter无法编写适当的.jtl文件这一事实很可能意味着JMeter有一个问题，即它被重载了，因此我认为您不能相信结果。所以：

1. 检查jmeter.log文件是否有可疑条目
2. 确保遵循JMeter最佳实践
3. 确保JMeter在CPU、内存、网络等方面有足够的运行空间。

Answer 3

这件事解决了。JMeter jtl文件被许多测试覆盖，因此它没有给出一个适当的o/p文件，并且在加载时产生了问题。通过提供jtl文件的新名称重新运行脚本解决了这个问题。
