Subject Re: Details on traffic server log Format
Date Fri, 23 Jan 2015 15:52:59 GMT
The traces above seem to be from traffic.out - the logs in this file are typically debug messages
that developers add with no particular *documented* format (Note: these traces are typically
not enabled in production for performance reasons - a very simple transaction can produce
100s of this messages depending on the debug tags activated). There's however a general recommended
format (per debug tag), that developers follow for uniformity/consistency when adding/modifying
traces in that area.
For the traces above - 
[Jan 23 10:43:54.024] Server {0x2baa8ff325c0} DEBUG: (http_cs) [17] session born, netvc

{0x2baa8ff325c0} : identifies the thread that's processing this session
(http_cs) : the debug tag associated with this trace[17] : the http sm_id (state machine id)
associated with this transaction
These identifiers usually help to group related traces for a given transaction/session/thread
etc and aid in isolating a specific unit of interest when looking through potentially a ton
of traces.
