Collect response time breakdown data
Collecting data on response time helps you analyze and diagnose performance problems in production and testing environments.
The data collection infrastructure must be installed, instrumented, and running on all the computers from which you are interested in collecting data.
Also, see Troubleshooting and unsupported scenarios for information about data collection limitations.
After you have identified how to re-create an application problem consistently, collect the profiling data surrounding the problem. In a production environment, you will import the relevant data from the IBM Tivoli Enterprise Monitoring Server. In a development or testing environment, you will enable collection of response time breakdown and then record the flow of execution within the application.
It is important to test the smallest possible portion of the application in order to focus only on the part that exhibits the problem. This will simplify the analysis later. If you are unsure of what the trigger is, you might have to collect more data and use more thorough filters to view the data.
