Configure Data Collection Dialog Box

Use the Configure Data Collection dialog to prevent the profiler from collecting information you do not need in order to increase execution speed and reduce memory consumption. The dialog contains the following controls:

• Locations —Specifies whether the profiler records locations that originate event so that you can navigate from events, operations, and items to the corresponding locations in sequence files and executions. Disabling this option can significantly improve speed and reduce memory usage. In particular, avoiding the overhead of storing location information can increase the accuracy of profiler times for operations that are very short.
• Process Models —Specifies whether the profiler collects events that originate from process models. To significantly reduce memory usage and improve speed, do not enable this option unless you want to debug or inspect the operations of a process model.
• Synchronization —Specifies whether the profiler records events from synchronization operations, such as Locks, Waits, Auto Scheduling, Queues, Rendezvous, Notifications, Batch Synchronization, and Semaphores.
• Steps —Specifies whether the profiler records the duration of each step.
• Step Modules —Specifies whether the profiler records the duration of each step module.
• Step Type Modules —Specifies whether the profiler records the duration of each step type substep module.
• Module Loading —Specifies whether the profiler records the duration of each module load.
• Module Unloading —Specifies whether the profiler records the duration of each module unload.
• Module Paths and Environments —Specifies whether the Operations Table populates the Module Path and Module Environment columns with the path to the code module and with information about the module execution environment that might affect performance.
• Module Inputs —Specifies whether the Operations Table populates the Module Inputs and Outputs column with module input values.
• Module Outputs —Specifies whether the Operations Table populates the Module Inputs and Outputs column with module output values.
• Limit Module Input/Output Text Length —If enabled, the numeric control specifies the maximum text size per row of the Module Inputs and Outputs column.
• Module Adapters —Displays a list containing a checkbox for each module adapter. Each checkbox specifies whether the profiler records load, unload, and execution durations for the modules that the adapter calls.
• Limit the Number of Retained Events —If enabled, the profiler periodically discards the oldest events it has collected if the number of events collected exceeds the specified limit. You can use this option to ensure that profiling continues indefinitely without excessively slowing execution or running out of memory.
• Limit the Duration of the Profile in Seconds —If enabled, the profiler periodically discards the events it has collected that are older than the specified duration. You can use this option to ensure that profiling continues indefinitely without excessively slowing execution or running out of memory.
• Specify a text file to log operations as they complete —Specifies the path to a tab delimited text file in which the profiler logs operations as they complete.
  • Browse for File —Launches the Select File dialog box in which you select a log file.
  • View File —Opens the specified text file in the default viewer application.
  • Create File/Clear File Contents —Creates or clears the log file and populates it with the appropriate headers.
