Websites Stress/Load Testing Question:

Often the first indication that something is wrong is the end user response times start to climb. Knowing which pages are failing will help you narrow down where the problem is.
Whichever load test tool you use, it will need to produce reports that will highlight the following:
Page response time by load level
Completed and abandoned session by load level
Page views and page hits by load level
HTTP and network errors by load level
Concurrent user by minute
Missing links report, if applicable
Full detailed report which includes response time by page and by transaction, lost sales opportunities, analysis and recommendations
