A . Review current application metrics and add new ones as needed.
B . Modify the code to capture additional information for user interaction.
C . Analyze the web proxy logs only and capture response time of each request.
D . Create new synthetic clients to simulate a user journey using the application.
E . Use current and historic Request Logs to trace customer interaction with the application.

Answer: DE

Explanation:

The most effective ways to measure application reliability from a user perspective without making any engineering changes are to create new synthetic clients to simulate a user journey using the application, and to use current and historic Request Logs to trace customer interaction with the application. These methods can help you monitor the availability, latency, and errors of your application from an end-user perspective.
