Which tool should be used to troubleshoot missing Adobe Analytics server calls?

Adobe Analytics tracking works by sending an image request (a server call) from the user's browser to Adobe's data collection servers. If these calls are missing, the issue is almost always on the client side. The Browser Network Tab, available in all modern browser developer tools, is the primary tool for troubleshooting this. It allows an analyst to monitor all outgoing network requests from a webpage. One can filter these requests to see if the specific image request to Adobe's tracking server (e.g., containing /b/ss/) is being generated and sent upon page load or user interaction.

B. Report Suite Data Processing Logs are on Adobe's servers. If a server call is missing, it never reached the server, so it will not appear in these logs for troubleshooting.

C. IP-Based Traffic Debugging is a server-side feature for isolating and debugging traffic from specific IP addresses, not for identifying why a client failed to send a request in the first place.

D. The Server-Side Data Warehouse is a feature for exporting large volumes of historical, processed data. It is an analysis tool, not a real-time debugging tool for missing client-side calls.
