I am profiling an application using the 4.5 agent controller; not the
integrated one in Eclipse, because I could not get my application to
talk to that, but the standalone downloaded one.
My application is a JNI invocation API application; I instantiate a VM
instance and invoke methods in it. I have added this option to the VM
parameters:
-agentlib:JPIBootLoader=JPIAgent:server=controlled,api=true; CGProf
The application's LD_LIBRARY_PATH includes these locations:
TPTP_AC_HOME=$HOME/app/tptp
JAVA_PROFILER_HOME=$TPTP_AC_HOME/plugins/org.eclipse.tptp.ja vaprofiler
TPTP_AGENT_LIB=$JAVA_PROFILER_HOME:$TPTP_AC_HOME/lib:$TPTP_A C_HOME/bin
LD_LIBRARY_PATH=$TPTP_AGENT_LIB:$LD_LIBRARY_PATH
export JAVA_PROFILER_HOME
export LD_LIBRARY_PATH
When I run the application, I am able to connect to it with the
profiler, but two issues appear:
First, I only have the option of execution time analysis, not memory
analysis, not anything else.
Second, even that doesn't work properly; I get an empty execution time
analysis result, with no packages highlighted at all.
I have run the same code in a non-jni environment, in a test harness
that is pure java, and in that case I get many options for profiling
(thread analysis, memory analysis, probe insertion, common base event
analysis...). This is still with the standalone agent controller, of
course.
So, how can I get my standalone java app to allow me to use the full set
of possible agents?

Your usage model falls under the definition of "dynamic attach". In
other words - you start your application from the command line, and then
attach to it from the Eclipse workbench. In this usage model, the
arguments you pass to -agentlib determine the data collector to load. In
you example, you specify CGProf, meaning that the "execution time
analysis" collector will be loaded. When you attach, you only see the
option in the GUI that matches the command line you specified.
Please refer to the JVMTI Profiler documentation (or its README file)
for the list of data collectors you can specify on the command line and
the configuration options available for each data collector.

Before you attach (from the Workbench), make sure the profiling filters
are set-up properly (double-click the "Java 1.5+" node in the Monitor
tab to see and edit the defined filters).
