Request Logging missing SERVER_IP
Using various devcentral articles and the Request Logging Profiles article I've made this template request logging template. It works pretty well, aside from the bold variables. I really need the $SERVER_IP and $SERVER_PORT information. Any ideas to why server and port isn't logged?
TMOS version: 13.1.1.5
Request Logging Profile:
Parent: request-log
Request Logging: Enabled
Template: $DATE_NCSA, $CLIENT_IP, $CLIENT_PORT, $VIRTUAL_IP, $VIRTUAL_PORT, $VIRTUAL_NAME, $VIRTUAL_POOL_NAME, $SERVER_IP, $SERVER_PORT, "$HTTP_PATH", "$HTTP_REQUEST", $HTTP_STATCODE, $RESPONSE_SIZE, $RESPONSE_MSECS, "$Referer", "${User-agent}"
HSL Protocol: TCP
Pool Name: syslog_pool
Example from the server
client: 203.0.113.245
vIP: 192.168.132.132
server: 172.17.17.15
