AltostratusThanks, this is what I originally suspected.
I tried searching around and couldn't find an answer which explains how the bigip server monitor functions. Does the GTM simply do a ping request to the LTM Virtual Servers every 30 seconds to check availability status and is the hold down timer 90 seconds before it's marked as Down?

AltostratusGot it, thanks for the clear explanation.
One last thing I'm curious about. If an LTM Virtual Server goes down (on a standard http health monitor check, that would be 3 failed health checks, meaning at the 16s mark), at what point is that corresponding Pool Member on the GTM marked down? Would it be immediate at the 16s mark where the LTM notifies the GTM of it's Down status?
Thanks
