Application controlled start/stop profiling within eclipse [message #96412]

Hi,

I've been profiling Java applications with TPTP from within Eclipse
(using the Profile As -> Java Application menu items) and it's been
working very well.

I now want to profile some applications that have a long start up time,
and I don't want to start profiling until the startup is over.

I understand that if I ran the application stand alone and used
server=application I could control when profiling is started/stopping
from within the application.

I can't see a way to do this from within the profiling options in
Eclipse. There is a "Automatically start monitoring when application is
launched" check box, but the documentation doesn't cover how to then
start profiling later.

Am I missing something? Thanks,
-Guy Coleman

Hi Guy,
Once you start your application stand-alone, you can attach to the
Profiler agent in the TPTP workbench (Run >> Profile... >> Attach - Java
Application).

Guy,

The "application" mode (server=application) should be used when you want
to control the profiler from within the application code. You use the
TPTP org.eclipse.hyades.collection.profiler.Profiler class to notify the
profiler when to start and when to stop monitoring.

This feature should work with the "old" (JVMPI) profiler. It is not
supported by the new JVMTI Profiler for Java 5/6.

To attach to a running application (as described in Paul's post), you
need to launch your application with "server=enabled" (or without the
server argument as "enabled" is the default) and not with
"server=application".

HTH,
Asaf

If you uncheck the option "Automatically start monitoring when application
is launched", then the agent will start in "pause" mode. You can start
monitoring the agent using the "Start Monitoring" toolbar item of the
profiling monitor view.
