how many listen directives is too many for haproxy configuration on a single node? What are the most important resources to monitor?

is 50 times the

listen qwerty213
  bind *:9124
  mode tcp
  option tcplog
  balance leastconn
     server zxcv 10.20.0.13:31527 check inter 3000
     [...]

too many? Or 100? (each one has several backend servers too)

Is there any limit after which haproxy performance deteriorates due to having a great number of open local ports which are connected to backend servers?

Thousands should be fine, the total number of health checks on backends may become an issue but ports are not. For a definitive answer you might want to try the HAProxy mailing list.
