Failing users are displayed in the VU column (d). To view the selected error, double-click it or right-click on a grid and click Show Sessions (e). The sessions will be retrieved from the test log and displayed in the session grid.
For quick error analysis, select a row, right-click, and select Compare with Recorded (f). The system will determine which user in which iteration encountered this error and then will display a tree which compares all replayed sessions for this user's iteration with the recorded sessions. This can help to discover preceding and subsequent errors and find out the root cause of the error faster. Another troubleshooting option is in the error view is right-click on the error and select See Waterfall (g) for this VU iteration.
