Getting trace infromation? [message #29058]

Hi everybody.

I'm trying to do the following thing: I need to make my plug-in that
analyze the trace of an excecution to detect posible causes of malfunction
based on components' responsabilities.
The questions are:
- How can I get the trace information? (Information that appears in the
UML2 Interaction Diagram view would be enough)
- How can I choose/generate/change a Profilig Set (Run Configuration)
programmaticaly from my plug-in?

Any help will be wellcomed, extension points to look at, api info,
examples, suggestions, ideas, anything.

thanks a lot!

Enrique

Hi Enrique,

I'm not exactly sure why you want to change the profiling sets
"programmatically" from your plug-in. That's not a trivial thing to do
and I
don't recommend it. However, if you do find it necessary, look into the
org.eclipse.hyades.ui and org.eclipse.hyades.execution.trace modules.
If you debug the PDCoreUtil class, you'll see how the options are being
setup and passed to the launch/attach functions.

It should be possible for you to generate the UML2 interaction diagrams
for your plug-in by profiling a runtime instance of your workbench. You'll
need to
select the "Execution History - Full Graphical Detail" profiling set to
get the UML2 diagrams. Profiling the workbench can be a bit slow,
especially if you select
the graphical options so make sure you filter out any of the data you're
not interested in.

thank you for the information.

I think I wasn't clear enough. I have already seen the UML diagrams, but
what I actually need is to get the information that is represented there
form my plugin and do some processing.

Thanks again. Please excuse me for my english.

It appears that you need to dynamically be able to control the profiling
agent that is profiling your plug-in. That's probably a doable task but not
a trivial one.

I'm not sure whether you are aware of the data entities and channels of
TPTP, so here's a quick rundown of what happens when you profile an
application:

1) Eclipse workbench which includes TPTP makes a request to the Agent
Controller to start profiling a particular application

At this stage, the workbench is acting as a client and requesting a service.
It is also at this stage that the configuration of the agent is sent.

2) The launched profiling agent (i.e. PiAgent) launches the application and
reports statistical data to the agent controller

3) The agent controller redirects all data to its client that requested the
service

4) The workbench takes the data and uses loaders to load the data in EMF
models

5) The views get populated based on the EMF models

It makes sense for you to write your own little agent controller client
(just as in step 1). It also makes sense to collect the raw data that is
sent from the PiAgent as opposed to the EMF model data that the UML 2 views
use. This way you can programmatically have control over the piagent. For
example you can determine when it should be started, what configurations
should be sent to it, when it should be detached, and when it should be
re-attached with new configurations.

Alternatively, if you did not have to change the configuration of the
piagent in the middle of its execution, you could have profiled your
application to a file and read in the file to monitor the health of your
plug-in. (there is a convenient way of profiling trace data to file in the
configuration launch wizard).

I would try the plug-ins and class files that Navid has noted as starting
points for your project.

Enrique,

If you want to get access to the =
org.eclipse.hyades.models.trace.TRCProcess (which is the root of the the =
profiling trace used in the trace views including interaction diagrams) =
you could take a look at =
/org.eclipse.hyades.use.cases/src/org/eclipse/hyades/use/cas es/junit/mode=
ls/test/TraceAndLogModelTest.java - loadTraceModel method - for a =
standalone example or if you run the TPTP UI you could listen for =
different kinds of selection change events that come from the Profiling =
Monitor or the other trace views (see =
org.eclipse.hyades.trace.ui.UIPlugin add* methods).

Please let me know if you need more info.

Regards,
Marius
