 +BACKEND MONITOR OR HEALTHCHECKS:\\
 +
 +This is a classical, added, monitor:
 +
 +  add lb monitor http-healthcheck HTTP -respCode 200 -httpRequest "GET /healthcheck" -LRTM ENABLED -interval 30 -resptimeout 20 -destIP 0.0.0.0 -devno 247431220
 +
 +Then in the backend server:
 +  dnf install httpd
 +  change listening port in /etc/httpd/conf/httpd.conf
 +  systemctl start httpd
 +  touch /var/www/html/healthcheck # so the 'GET /healthcheck' succeeds
