Virtual Server IP Address in SERVER_DATA event
We have a straight up load balancing VS for UDP DNS running on an LTM license. To meet some logging and analytic requirements, I want to include the IP address of the VS inside the SERVER_DATA event. According to the documentation, IP::local_addr and IP::server_addr will report the BIGIP source IP or SNAT (depending on configuration). I can't locate a way to reference the VS address...can get it in the CLIENT_DATA event, however the SERVER_DATA event is elusive. Is there a method to get the VS address inside SERVER_DATA? I've examined using a global variable set in CLIENT_DATA event, however that kills CMP and as this is expected to have performance ramifications I'd rather avoid.
