There is a logging part in the doc but I haven't seen such entries in the document. http://cbonte.github.io/haproxy-dconv/1.7/configuration.html#8 Maybe you have activated http://cbonte.github.io/haproxy-dconv/1.7/configuration.html#4.2-option%20log-health-checks in your config. It would be nice to know which haproxy version you use. haproxy -vv -- Best Regards Aleks https://www.me2digital.com/
