Running an Activity and collecting performance data

Procedure

  1. Select an Activity that is in the new state in the Performance Explorer view.
  2. Click the Begin Data Collection button in the bottom panel of the view.
  3. During data collection the Activity goes into the running state.
  4. Wait until the data collection process completes.
  5. The date and time that the Activity completed will be displayed next to the activity name.

    You are now ready to analyze the collected performance data.

    If the Activity was the first Hotspot Detection Activity to be run for the Session then it will automatically be marked as the baseline. This represents the state of your application before any performance tuning has been done. As you create new Hotspot Detection Activities you can compare their performance against the baseline.
