调研方向

未指定任何文件、测试或入口点。首先检查 ApplicationInsights-Java 中现有的采样和遥测行为,然后明确基于 tail 的规则应如何处理缓慢的依赖项以及失败的 span 或 trace,之后才能认为实现已完成。

描述

Is your feature request related to a problem? Please describe.
We want to have more control over sampling in our application.

  1. Don't record dependencies that are less than 100ms(successpath), but record everything that is >100ms. (numbers are arbitrary)
  2. Record 100% failed telemetry(span/trace/etc) as described here https://github.com/microsoft/ApplicationInsights-Java/issues/3511 . Recording only exception doesn't give much context if everything surrounding it is sampled.
    We want to lower our costs but also have useful telemetry, I believe having tail based sampling would greatly help us.
