Hello community !
I looking for a solution for my specific need. I have HAproxy servers which are serving huge amount of traffic (peaks with more than 60000 req/s). Currently, HTTP logging is not enable for normal traffic (option dontlog-normal), traffic volume is to high to permit logging in good condition.
I’m looking for a solution to evaluate how many client are SNI compatible. This can be achieve with custom logging format with “%[ssl_fc_sni]”.
Do you know if there is a way to enable HTTP logging only when matching criteria (such as the presence of SNI host field) ?
