There are gaps in my response time data when I play back scripts

The problem: There are gaps in the response time data when I play back Rational Performance Tester scripts.

This may occur for a number of reasons.

The solution:

If the robotic playback interval is longer than the aggregation interval, there may be gaps in the response time data because some play backs do not fall in the current aggregation interval. Match the aggregation interval in the Robotic Response Time agent configuration and the play back interval in the robotic script profile to overcome this problem.

If you request retries in the script profile, the total playback interval with retries may again be longer than the aggregation interval resulting in intervals with no response time data reported.

If the gap in the response time data is regular, for example twice per hour at 10:10am and 10:40am you may have a configuration setting problem. Ensure that the Aggregate Period Minutes configuration setting for Robotic Response Time is greater than or equal to the Collection Interval value for the Robotic Response Time transaction.
