App Insights Analytics - 如何提取价值并在日常水平上显示它们

App Insights Analytics - how to extract values and show them on daily level

我在 App Insights 中有自定义数据。数据具有如下结构: EventType 可以是 installuninstall。除此之外,我还有 System,可以是 System1System2System3...等

如何获取系统每天 categorized/sorted 的安装/卸载数量?

像这样:

myDataSource
| summarize 
     Installs = countif(EventType == "install"), 
     Uninstalls = countif(EventType == "uninstall)
  by System
