The source address is the self address based on the routing to the back end servers. Something similar has been asked before and the solution suggested was to use an external monitor running a script or command that allows a custom source address. The latest I found was here:

Alternately, you could use inband passive monitoring which looks at the client connections but would depend on what exactly you need to monitor.
