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.
