F5 Local traffic Pool -> How does it track the availability of the members of the pool?

Hi Team,

I would like to understand how the Pool works on F5, please.

In terms of F5 Local Traffic Pool, how does it track the availability (green/red) of the members of it?

I mean, does it use the F5 management IP as a source for this tracking ?

Is there a way we can configure the source to be a specific Self IP? If yes, how is that done?

Thank you

Rodrigo
