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.

    As per my testing, LB_SELECTED is not triggered for each HTTP requests. Depending on settings like persistence, Load balancing, OneConnect Profile etc, LB_SELECTED may not be triggered all the time. So I would recommend you run below irule

     

    when LB_SELECTED {

     

    Once pool member has been selected log it.

     

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

     

    }

     

    when HTTP_REQUEST { Once pool member has been selected log it. log local0. "Selected member: [LB::server addr]" }
