Radius "MONITOR" option

The load balancer sends the health-check on udp/1813 with only
"Monitor" in the payload (per a sniffer capture).  From my
understanding - this health-check is not a properly formatted radius
packet?  The expected response is the exact same - a packet from
udp/1813 with only "Monitor" in the payload.

Is this possible with Free Radius with a reply message?
