+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
