GTM health monitor connection refuesd

[caulfiedd_spurr]

in the GTM setting , probing interval is 30 sec , timeout is 120 sec . I am not sure if the node under GTM response connection refused (TCP RST). before GTM mark the node down  still need to wait 120 sec ?

The endpoint gets 120 seconds to respond but GTM will mark it down as soon as it gets an unhealthy response (TCP-RST)

LTM and GTM monitors have a few slight differences. But you can make a GTM monitor act more like an LTM monitor by checking the Ignore Down Reponse checkbox. This will give the endpoint the chance to reply with a healthy response for the entire timeout value before marking it down
