When we were discussing this on the whiteboard, we had the full deployment model at the level above the leaf nodes (where leaf nodes have container IDs for their names). This way we could scan the tree and see whether the stream was at 100% health, e.g.:

````
/xd/streams/mystream/source/http-0/111
/xd/streams/mystream/source/http-1/222
/xd/streams/mystream/source/http-2/
/xd/streams/mystream/source/http-3/444
````

In the above example, we would know that the "http" source module is only at 75% of the requested number of instances as prescribed in the deployment manifest.
