if you want log each and every connection request, use below

 

when HTTP_REQUEST {

 

Once pool member has been selected log it.

 

log local0. "Selected member: [LB::server addr]"

 

}

Hi Noushad,

 

I have tested your suggested in my lab,but it is not working. while HTTP_REQUEST is not able to detect the pool member.

 

L4L7 iRule is working fine and it gives the correct output.

 

Output: "Rule /Common/LB_SELECTED_Log_pool_member : Selected member: 10.1.20.11"

 

Thanks Noushad and L4L7 for iRule.
