If I undestand your question correctly you can use monitor-uri and monitor-fail on S1/S2 haproxy. And healthcheck the monitor-uri from balA/balB. (http://cbonte.github.io/haproxy-dconv/1.7/configuration.html#4-monitor-uri http://cbonte.github.io/haproxy-dconv/1.7/configuration.html#nbsrv) So in S1/S2 haproxy: monitor-uri /healthcheck monitor-fail if { nbsrv(your_backend_name) lt 1 } And in balA/balB: option httpchk GET /healthcheck ... http-check expect status 200 (http://cbonte.github.io/haproxy-dconv/1.7/configuration.html#4.2-option%20httpchk) -Jarno -- Jarno Huuskonen
