Amongst the additional metrics I (For Dante) would wish to see (note 
that we haven't decided yet for which MA to go for), I would mention:
- Input error (which one/s is/are the most meaningfull?)
- Output drops (per interface, per queue/service)

Input errors:
    Errors: 0, Drops: 0, Framing errors: 7, Runts: 0, Giants: 0, Bucket 
drops: 0, Policed discards: 0, L3 incompletes: 7, L2 channel errors: 0, 
L2 mismatch timeouts: 0, HS link CRC errors: 0, HS link FIFO overflows: 0
  Output errors:
    Carrier transitions: 1, Errors: 0, Drops: 0, Aged packets: 0, HS 
link FIFO underflows: 0, MTU errors: 0
  Queue counters:       Queued packets  Transmitted packets 
Dropped packets

Szymon mentioned that multi-domain will not be ready for that release.

If I had to remove a service for this list, this is the one I would 
remove as it is specific to a vendor used only by two networks. In 
addition, there is no pressing need from JRA4 to provide such feature in 
the next few months.

To all, please mention which service need it released by September.

Must be for all the service released.

- LS registration and keepalives, etc must be for all the services released.

Yes.

My 2 cents.
