Optional logging metrics for rule applications

Tobias has suggestions around adding useful metrics for rule applications.

Context:

"It would be extremely helpful to have metrics about how often a rule was applied, how often it was violated, and how long evaluation took.
It could be controlled via opt-in so logging is off until you turn it on.
This way, we all could identify the rules violated most often, and initiate educational initiatives, plus find out more about rule quality and relevance.
The best way to consume this info would be through event logs. This would not replace my original suggestion of having a “-Diagnostic” switch. The –Diagnostics switch would apply to the current scenario only and return metrics immediately.
"

该 issue 没有指出文件、测试或入口点。首先定位规则应用和评估的位置，然后确定 opt-in 事件日志记录和拟议的诊断开关应如何暴露应用次数、违规情况和评估耗时。
