To Collect Data From a Running Process Using the collect Utility

1. Determine the program's process ID (PID).

   If you started the program from the command line and put it in the background, its PID will be printed to standard output by the shell. Otherwise, you can determine the program's PID by typing the following command.

   % ps -ef | grep program-name

2. Use the collect command to enable data collection on the process, and set any optional parameters.

   % collect -P pid collect-options

   The collector options are described in Data Collection Options. For information about clock profiling, see Clock Profiling with the -p option. For information about hardware clock profiling, see Hardware Counter Profiling with collect -h.
