我很难理解 locust 结果,因为这是第一次对我的服务器进行负载测试,我在当地时间 00:00 使用命令行运行了 locust;1000 个总用户,每秒 100 个孵化和 10000 个请求。下面是结果

这是我感到困惑的地方:

  1. #reqs、#fails、Avg 下方的数字以及第一张和第二张桌子上名称后面的所有数字是什么意思?是显示已发送总请求还是已发送第 n 个请求?
  2. 在 # 次出现以下的错误报告中,总数是否代表导致错误的请求数?

感谢您的回答

第一个表格显示了与每行相关的统计信息,并以毫秒为单位给出了列说明,但总原始数据显示了每个给定列的总数。但是,在您的示例中,计算每种原料的失败百分比存在问题。对于第一个 raw:发送了 452 个请求,但其中 203 个请求失败,这意味着203/453 ~= 44.81%在总 raw 中计算正确。

第二个表是分布表,显示了在给定时间间隔内完成请求的百分比,在表中表示 50% 的到家请求在 6500 毫秒内完成,66% 的请求在 8300 毫秒内完成并分别继续。
