Starting a Performance Profiling Session

Performance profiling is initiated by running the profctl utility on the target system, with the -start option. This utility considers the components to be profiled as arguments.

If the_process was part of the system image, use the following command to initiate the performance profiling session:

% rsh trumpet arun profctl -start -b the_process

If the_process was loaded dynamically, use the following command:

% rsh trumpet arun profctl -start -a the_process pid

Where pid is the numeric identifier of the process (as returned by the aps command).

Run the application.

Several components can be specified as arguments to the profctl utility.
