Abstract: A method, non-transitory computer readable medium, and network traffic management apparatus that receives a response to a ping message from a server device in a server pool and determines a current latency value based on a time difference between when the ping message was sent to the server device and when the response to the ping message was received. A determination is made when the current latency value exceeds an adaptive threshold latency value. The adaptive threshold latency value is based on an average historical latency value and an established threshold factor value. A deficient response value is incremented and a determination is made when the deficient response value exceeds a deficiency threshold value, when the determining indicates that the current latency value exceeds the adaptive threshold latency value. A mitigation action is initiated when the determining indicates that the deficient response value exceeds the deficiency threshold value.
