Hello Ali,
I read the Word attachment related to enhancement 139085
where you propose to remove the "Monitor" tab in favor of
the "Agents" tab. Is that only for the "Attach" launch
configuration, or for all?
Our tools typically launch an agent (not a process) and
attach to it. We are also trying to define our own common data
format for our analysis tools. The concept of data collectors,
analysis types and the associated profiling UI seemed to fit
nicely.
It becomes confusing when there are agents that don't
have a data collector, like the logging agents. Is there
a document that describes the relationships between agents,
processes, data collectors, analysis types and launch items?
I found the launch entities diagram helpful, some additional
explanation would be even more helpful.
Is there a way to attach directly to an agent while avoiding
using the Agent Controller? I was hoping that the
IDataCollectorAgentLauncher interface would let us do that.
Can this also be done using the "Attach" scenario as you
suggested (the Java-attach case uses the AC)?
Thanks again, and also for improving the Attach scenario

forprocess-less data collectors
Hi Henk,
There is actually a process that is launched by the Agent
Discoverer. The process that is launched is periodically queried to
determine if there are any agents associated with it. As soon as an
agent is discovered, it is automatically attached and monitored.
I believe your use case is different. You intend to use the
launch configuration to only discover an agent that is already running
on a particular host. Although this is currently possible (using the
Attach - Java Process launch configuration type), the use case is a bit
obscure and it is being redone in 4.4. Please see the following
enhancement:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=139085
Thanks,
Ali Mehregani

My goal is to use the launch framework for
configurations
that attach to agents without launching a process. I
started
looking at The Agent Discoverer as a sufficiently close
example.
Unfortunately I got confused by the logic that is
executed for
this case (I use the "Java Application" launch
configuration):
The confusing thing is that, even though the Agent
Discoverer
is really an agent object, in this particular case the
agent
returned to the primary launch delegate must be null.
Then,
even though no process is associated with it, a dummy
process
of class CustomProcess must be created to circumvent
some
problem with the RAC. Then later a dummy agent of class
DummyAgent is created to simulate an active event, in a
rather obscure place/logic path.
What I would expect in this case is just the opposite,
namely that a non-null agent is returned to the primary
launch delegate, and that the logic of how to launch a
process-less data collector is implemented in the
primary
launch delegate itself, without a need for a dummy agent
and a dummy process.
I tried modifying the CustomDelegate example documented
under "Registering a Custom Data Collection Mechanism
with
TPTP's Launch Configuration Framework " by implementing
IDataCollectorAgentLauncher instead of subclassing off
AbstractProcessLauncher but then no tree node
representing
an agent shows up in the profile monitor.
Thanks in advance for any advice,
