Found my way out with following iRules. Thank you for the answers!

-------------------------------------------------
 irule HSL
-------------------------------------------------

when CLIENT_ACCEPTED {
   set hsl [HSL::open -proto UDP -pool pool_remote_log_servers]
   set static::bigip [info hostname]
}

when HTTP_REQUEST {
   set ReqLogString "Client [IP::client_addr]:[TCP::client_port] -> [HTTP::host][HTTP::uri]"
   set virtual [virtual]
   set virtual_ip "[IP::local_addr]:[TCP::local_port]"
   set http_request_time [clock format [clock seconds] -format "%Y/%m/%d %H:%M:%S"]
   set referer [HTTP::header value referer]
   HSL::send $hsl "$static::bigip $virtual ($virtual_ip) $ReqLogString (request) - $http_request_time $referer"
}

when HTTP_RESPONSE {
    set lb_server "[LB::server addr]:[LB::server port]"
    set ResLogString "ServerNode $lb_server -> Client [IP::client_addr]:[TCP::client_port]"
    set http_response_time [clock format [clock seconds] -format "%Y/%m/%d %H:%M:%S"]
    HSL::send $hsl "$static::bigip $ResLogString HTTP ResCode= [HTTP::status] (response) - $http_response_time"
}
