One thing I've done is to ensure my object naming conventions - VIP, Self, VLANs, etc. - also identify what data center and / or what unit the object exists on. When you do that, you can easily identify a VIP that exists in DC1:BIG-IP1 versus an object on DC3:BIG-IP2 just by looking at it in BIG-IQ. When I have not done this, I see a million SelfIPs that all look the same.. I can't tell my Drupal VIP in DC1 from my Drupal VIP in DC2, etc.
