What is axNetStatTCPSYNCookieSentFail?
This counter measures failed attempts to send TCP SYN cookies, indicating resource exhaustion during an attack. A non-zero value warns that the load balancer ran out of memory or handles to continue protecting against SYN floods. Values above zero demand immediate investigation—for example, 50 failures suggest the device is overwhelmed.
