-------------------------------------

Hi [~thobbs], can you give some more details on what we mean by "log client address in query trace"? 

Do we need to add a new event in the events table of the system_traces keyspace or just add the client IP address to the first line like so:

{code}
Tracing session: b66ef150-c24a-11e4-a915-e3263299699d

 activity                                                                                                              | timestamp                  | source    | source_elapsed
-----------------------------------------------------------------------------------------------------------------------+----------------------------+-----------+----------------
                                                                                     Execute CQL3 query from 127.0.0.1 | 2015-03-04 00:44:47.205000 | 127.0.0.1 |              0
[...]
{code}

Or do we mean something completely different?

Thanks!
