Logs full TCP incoming and outgoing packets

[florent]

Hello everybody,

For an application, I use haproxy in TCP mode but I would need to log, 
from the main load balancer machine, all the TCP transactions (incoming 
packets sent to the node then the answer that is sent back from the node 
to the client through the haproxy load balancer machine).


Is it possible to do such a thing ? I started to dig in the ML and found 
few information about capturing the tcp-request, which does not work for 
now... and I need the response as well... so preferred to ask if someone 
have got an experience doing this. Sure, it will have a performance 
penalty but exhaustive logging is more important than that and it it the 
best solution to avoid a lot of changes in the existing infrastructure 
we just load-balanced.


Best regards,
Florent
