Health checks will always come from the self IP, not a SNAT.

 

SNATS are for traffic.

 

Yes it's okay to monitor tons of nodes with one self ip.

 

Hope that helps! If it does please up-vote and select this answer, it'd be greatly appreciated!

Yes a SNAT pool works basically the same as a floating IP.

 

If you have a VIP set to AUTO-SNAT, it will SNAT to the floating IP.

 

If you have a VIP set to SNAT, it will use the SNAT pool addresses.
