A folk-festival box office on App Service shows HTTP 500 entries in the platform web-server log, but the ASP.NET exception text written through ILogger never appears. What should the developer enable?
Select an answer to reveal the explanation.
Short Explanation
Web-server logs are the ticket window’s door counter—they know a 500 happened. Application logging is the clerk’s notebook with the actual error story from your code. Turn on both families when you need the exception text, not just the status.
Full Explanation
App Service exposes distinct logging families: web-server (HTTP) logs and application logging that captures stdout and framework logging such as ILogger. Platform 500 entries without application logging enabled will not include the exception detail written by the app. Application Insights is valuable for Domain 4 telemetry but does not erase the need to understand App Service’s own application versus web-server log settings.
