".NET CLR 异常数\# 引发的异常数/秒"性能规则

Microsoft.Windows.InternetInformationServices.10.0.WebServer.NumberOfDotNetExceptionsThrownPerSecond (Rule)

此计数器显示每秒引发的异常数目。其中包括 .NET 异常以及转换为 .NET 异常的非托管异常，例如，非托管代码中的空指针引用异常将在托管代码中重新引发 .NET System.NullReferenceException；此计数器既包括已处理异常也包括未处理异常。异常应仅在极少情况下而不是在程序的正常控件流中发生；此计数器被设计为由于引发大比率异常 (>100s) 而发生潜在性能问题的指示器。此计数器不是一段时间的平均值；它显示最近两个样本中观测的值的差除以样本间隔时间的结果。Nano 上不支持。已使用 Nano 的替代禁用。
