Visibility of connection / DICOM stream

[BRIT]

Using DCM4CHEE 2.x, from all of the queues available in the JMX, does anyone know if there's a queue that shows

1. Current connection(s) to the DICOM server and/or
2. Any data being transferred to/from the DICOM server and/or
3. How busy the server is (diskspace is available I understand, but from a processing point of view)

I've been sending a boat load of data through to the server, but no matter which queue I seem to pick, I don't appear to get any of this information back?
