Use SNAT with Monitor

As Chris said, there isn't a native method for selecting the source IP of a stock monitor. You can use an external monitor which references a shell utility that allows for selection of a source address.

 

 

However, you can't use shared IP addresses (floating self IP's, SNAT addresses, etc) in a redundant pair as that would cause IP conflicts when each LTM unit attempts to perform the monitor checks.
