There are no samples for automated profiling scenarios, although if you dig
in the code you'll find all the pieces that you'll need, the only problem is
most of them are internal so they can change at any time.

You could automate profiling in two ways:
    -profile the application in standalone mode then load the raw trace into
the trace model using org.eclipse.hyades.loaders.util.XMLLoader
    -profile the application in controlled mode like the UI does and load
the trace events as they are received, check how the
org.eclipse.hyades.trace.ui.internal.piclient.XMLTraceDataProcessor class is
used (involves also
org.eclipse.hyades.trace.ui.internal.piclient.PIProcessListener), you could
also achieve this by driving the Hyades UI with some UI playback tool.

In the Trace views you can take HTML snapshots of the statistical view state
(see
org.eclipse.hyades.trace.views.internal.StatisticView.printColumnsToHTML),
although that is not applicable for headless mode.

You are right, that was just another example of performance testcases that
were part of the build process.
In Eclipse I think they just have JUnit based testcases tailored to gather
performance info with no Hyades test or profiler infrastructure involved or
at least not in the build.
In Hyades we will continue to add Hyades testcases (see
org.eclipse.hyades.tests, check also the hyades-dev mailing list archive for
more info about this component), so we could also add performance testscases
using profiling data (BCI or JVMPI based).
The intend is to integrate Eclipse JUnit and other JUnit based tools support
with Hyades Test infrastructure (including Hyades JUnit support), see
http://www.eclipse.org/test-and-performance/.

Marius
