Just want to confirm,
supposed the health monitor has interval of 5 secs and time out at 16sec - DEFAULT settings.
Does this mean that even if the pool member is down for let say 1 seconds, F5 won't mark it down?
F5 will only mark it down after 16 seconds.
Is this correct?
the F5 will check every 5 seconds. After 16 seconds, if it has three consecutive failed checks (5 sec+5sec+5sec+1sec), it will mark the pool member down. It's basically three checks plus 1 second.
This way the F5 can send three health checks and it provides a reasonable amount of time to for the pool member to reply.
