Application Insights诊断异常率指标

Question

我有几个服务可以登录到单个Application Insights实例：

• 服务结构服务
• Azure AppService / WebApps

可以通过属性（ComponentName）来区分其遥测条目。

我看到“异常发生率”指标表明某些时期的异常计数很高。但是，“例外”指标完全不显示任何例外。这可能意味着异常全部由用户代码处理，并且“仅是可能的性能问题”。否则，它们将无法处理并且无法通过TrackException进行跟踪。

但是，如何最好地找出我的一项服务导致了如此高的费用？我怀疑它是AppService之一，但我不知道是哪一个以及在哪里引起异常。

可以更改我们的ApplicationInsights.config帮助吗？这是我们目前的那个。
