Further to the original question: how does the BIG-IP select the health monitor source IP if there are multiple Self IP's on the same interface / VLAN?

 

Is there a rules set to define this, and can it be manually set for deterministic monitoring?

It uses routing - ie it will follow it's self-IP/specific route/default route etc
