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]" }
