You can profile an application to capture performance information for an existing
project.
Before you start:
- The process must be running on the target with profiling enabled.
To profile a process from an existing QNX C/C++ project that's already running on
your target:
-
While the application is running, open the Launch Configurations dialog by
choosing from the menu.
-
Select C/C++ QNX Attach to Remote Process via QConn (IP)
from the list on the left.
-
Click the New button to create a new attach-to-process
configuration.
-
Configure things as you normally would for launching the application with
debugging.
-
On the Tools tab, click Add/Delete
Tool…. The Tools Selection dialog is shown.
-
Select the Application Profiler tool, then click
OK. The Application Profiler
tab is displayed on the launcher.
-
Select Switch to this tool's perspective on launch.
-
Click Apply, and then click
Debug. The Select Process dialog shows all of the
currently running processes.
-
Select the running process you want to profile, then click
OK. Now, you can begin to analyze the profiler
data.
