Hi Bobby,
I'm fully with you. You want to isolate transactions, you want to isolate maybe a complete Business Transaction from the very beginning to the end. Maybe even add a component which are in the middle of a JVM which doesn't show about on Team Center at the moment because we currently have the restriction to Frontends and Backends. I can tell you we just started ;-) .. a lot of cool stuff is coming..
Let's talk in a very few month from now again about Datapower and WebSphereMQ/Broker.
For now, try to work instead of isolation with the "Highlighting" view options. Once you set a custom attribute you can highlight it all through your environment. That's what it is built for.
I also fully agree with you on the limitation of the filters. That's why I recommended to use the attribute "tier" very excessive. You can define rules to set the tier and you can use it for filtering.
Once you have a few perspectives based on custom attributes, use the existing filters with attributes you can set like "location", "owner" and "tier" and next combine it with the Highlighting, I'm sure you will have most what you need in seconds on your next bridge call.
Cheers
Andreas
