I have already searched on devcentral & applied similar monitors available on discussion but it failing on configuration on BIG-IP.the monitors shows down.
please also let me know the some test to do from cli of BIG-IP system to successfully configure such monitor.
If you would like to assign monitor to pool or pool member you can just create new based on http or http head and then set Alias Address to google or tcs, not sure if it has to be IP or can be FQDN. Check as well this one DevCentral - An F5 Technical Community Piotr
