 ### Microsoft.WebBrowser.Installer.EdgeUpdate.Ping
 
-The Ping event sends a detailed inventory of software and hardware information about the EdgeUpdate user's version, app usage, update usage, and hardware capabilities. This event contains Device Connectivity and Configuration, Product and Service Performance, Product and Service Usage, and Software Setup and Inventory data. One roll-up event is sent each time any installation, update, or uninstallation process, including an error, occurs in the EdgeUpdate service. Each Ping event can contain an arbitrary number of apps which have been modified, and each of these apps in turn can fire multiple event types. This event is used to measure the reliability, performance, and usage of the EdgeUpdate service.
