LTM monitor - help

Your question is not well written but this will just check the example1.test..co.uk as I think that you are using Virtual hosts on your server (https://en.wikipedia.org/wiki/Virtual_hosting)?

Keep in mind that by default if a minitor goes down the pool member will go down but you can change this by using the option "Pool member availability":

Also you may create a transperant monitor if you want to check something that is not the pool member itself (used for firewalls or to check the real servers after API gateways):
