Which action will provide real-time access to connection errors in webapp1?

Enabling web server logging is the most effective action for gaining real-time access to connection errors in webapp1. Web server logging captures detailed information about every request made to the web application, including error messages, status codes, and other relevant diagnostics. This logging runs in real-time, allowing administrators to analyze incoming requests and troubleshoot issues as they arise.

This action helps to identify connection issues immediately as users make requests to the application, providing critical input for diagnosing problems quickly. The logs can typically be routed to various storage solutions for deeper analysis and can be viewed in the Azure portal, simplifying management.

Other options provide valuable insights but are not tailored for direct real-time monitoring of connection errors in the same way. For example, creating a workbook in Azure Monitor allows for visualization of data but does not necessarily capture real-time error data directly. Similarly, setting up Service Health alerts will notify you about broader service issues within the Azure environment but may not focus directly on the specific connection errors within webapp1. Turning on application logging will capture application-level events but may not provide the same level of detail about web server-specific connections as web server logging does.
