Which logfile should a DevOps engineer analyze to evaluate response performance in an AEM environment?

• A. response.log
• B. request.log
• C. replication.log
• D. access.log

Answer: (B)

Measuring how long AEM takes to handle each request is the key to evaluating response performance. The per-request processing times are captured in the request log, which records details for every Sling request, including how long the server spent processing it, along with the HTTP method, resource, and status. This makes it the most direct source for understanding application-level response performance and identifying slow endpoints or patterns over time. In contrast, the web server access log (access.log) shows requests from clients at the edge and can include a total time, but that duration blends network, dispatcher, and server overhead and may not isolate AEM’s internal processing time. The replication log tracks content replication events between instances, not user request handling. A log named response.log isn’t a standard part of AEM logging for performance analysis. So, for a clear view of how quickly AEM responds to client requests, focus on the per-request data in the request log.
