How to monitor internal IP translate to which ip snat in pool

I have some issue about logging by iRule

 

 

external internal (server-pool)

 

server --------- F5 --------- server1, server2

 

2.2.2.100 1.1.1.100, 1.1.1.101

 

snat-pool: 2.2.2.251, 2.2.2.252

 

 

How can I know what the ip of snat-pool used to translate by which server in the server-pool?

 

iRule

 

Irule when SERVER_CONNECTED {

 

log local0. "client_addr [IP::client_addr]"

 

log local0. "remote_addr [IP::remote_addr]"

 

snatpool snat-pool

 

log local0. "client_addr [IP::client_addr]"

 

log local0. "remote_addr [IP::remote_addr]"

 

}

 

I tried this but it doesn't work it show only ip of server and destination server, doesn't show ip that be translated.

 

 

thank you
