this irule will do it, I hope you don't have a lot of traffic on the VIP! are you sure the every 5 second hit on the proxies isn't the F5 health checks from the primary and standby?

 

Log-all tcp traffic to a vip,

 

when CLIENT_ACCEPTED {

 

set vip [IP::local_addr]:[TCP::local_port] }

 

when SERVER_CONNECTED {

 

set client "[IP::client_addr]:[TCP::client_port]" set node "[IP::server_addr]:[TCP::server_port]" }

 

when CLIENT_CLOSED {

 

log connection info log local0.err "Client $client -> VIP: $vip -> Node: $node"

 

}
