I have a HAProxy setup in front of Apache webservers for load balancing. Health checks for these webservers are also configured in HAProxy.
option httpchk HEAD /healthcheck.txt HTTP/1.0
Is it possible to transfer these health check requests to backend webservers as
User-agent or any other option, so that I can distinguish them from other log entries?
(I don't want to go for the
dontlog" option, as I don't want to miss these entries.)
