Wow, as I can see there's a lot of work going on in the area of DAnCE.
Is it correct, that this Target Manager is part of the OMG D&C
specification?
I recognized that there is already a Target Manager executable in the
DAnCE sources integrated with CIAO.
What is the current state of the development there?

Will this include the interconnections between components and their
performance parameters, like connection response time, ...?

two ways, first it will enable run-time detection of interesting events

Is it possible to provide a complete view of the running assembly, including
all running components and its connections?

Will this be implemented as a standalone executable or is it planned
to integrate this  functionality into something which exists already?

Thanks a lot for pointing this out. It is interesting to hear that
the information necessary for component monitoring can be retrieved
from standard D&C tools.

Thanks,
