   There is one small problem with the diagram as it currently stands : 
lttng-relayd does not intervene on the sender side.  When sending the trace 
data to a remote location, the lttng-consumerd reads from the buffer and sends 
over the wire instead of writing to the local file system.  On the destination 
machine, lttng-relayd receives the data and writes it to the destination 
machine’s local file system.  The first lttng-relayd box of the diagram does 
not exist.

   Finally, you may want to add a control arrow running from Eclipse TMF to the 
session daemon (this is achieved through SSH, as far as I can recall).
