Profiler Operation

Whenever you launch the Profiler or attach it to a running application, a Profiler process is started. The Profiler operates by taking samples from the target process at intervals of up to 250 milliseconds. At these intervals the Profiler interrupts the process and collects stack information for all threads running at that time; this information is sent back to Enterprise Architect where it is collected, sorted and and stored.

Start a Profiler Process


Click on the Run Profiler button on the Profiler window toolbar.


End a Profiler Process

The sampler process exits if:

You click on the Stop button
The target application terminates, or
You close the current model

If you stop the Profiler and the process is still running, you can quickly attach to it again.



Pause and resume a session

You can pause and resume profile sample collection at any time during a session.

When sampling is turned on or resumed, the Profiler process becomes active and samples are collected from the target; resuming sampling collects completely new samples.

The Profiler process idles if sampling is turned off or paused during a session. The Report and Discard Data buttons then become enabled.
