How to get server IP when LB_Selected


when HTTP_REQUEST {
   set clientIP [IP::client_addr]
}
when LB_SELECTED {
   set serverIP [serverside {IP::remote_addr}]
}
when LB_FAILED {
   log local0. "LB Failed for client $clientIP and server $serverIP"
}

I am trying to grab the server IP when the the LB selection is made. However, it is saying that IP::remote_addr is undefined in the serverside context at the time of this event. What is the right way to get this?

    Try this

    
when HTTP_REQUEST  {  
    set clientIP [IP::client_addr]
}
when LB_SELECTED  {   
     set serverIP [LB::server addr]
}
when LB_FAILED {   
     log local0. "LB Failed for client $clientIP and server $serverIP"
}
