how can I enable logging of haproxy check results (or failures only)? I've seen some mailing list posts suggesting this is possible:
Server LDAPSFarm/LDAPS1 is DOWN, reason: Socket error, check duration: 277ms. 1 active and 0 backup servers online. 0 sessions requeued, 0 total in queue.
but I don't get the same results. My config is more of less this:
global log 127.0.0.1 local0 user haproxy group haproxy spread-checks 5 defaults log global mode http option httplog option dontlognull retries 3 redispatch maxconn 2000 stats enable stats hide-version option allbackups listen XXX YYY mode tcp balance roundrobin option httpchk / server XXX-1 ZZZ1 check port 8080 inter 2s rise 15 slowstart 10s server XXX-2 ZZZ2 check port 8080 inter 2s rise 15 slowstart 10s
If I enable statistics page and look at it, I can see that sometimes server lines go yellow/red which suggests monitoring failures, but currently I don't see anything related in the log files. How can I get this information?
