Health monitor question

For example, if I have a monitor with 5 interval and 16 time-out?. What will happen if the pool member fail to response the second health check and the pool member still appear as up, it will still the F5 send traffic to the node that fail one of the heath check?

  • If it failed a health check the member will be marked as down, and will not receive traffic.

     

    If it passes the first health check and is still within the 16 second timeout of the second, but is going to fail, it will receive traffic until the timeout fails and the member is marked as down.

     

    Hope that helps! If it does, please up-vote and select this answer, it would be greatly appreciated!

      No sorry, what I want to know is if the first health did not get a response, it will the F5 still send traffic to that pool member until it reach the time-out value and hence mark the pool member down

      Yes it will send traffic until the time-out (when it is marked down)

      Yes, bigip will continue to send traffic to a pool member until it is marked down. If the timeout period is 16 seconds in the monitor then bigip will send traffic for that time at which point pool member is marked down and bigip stops sending traffic.
