You should know the timeout value. Timeout usually is configured as 3x+1, where x is the interval value.

 

If your interval is 15 and timeout is 46, it means, the F5 monitor sends Get request every 15secs, and the recv string if got, it marks it as UP.

 

If not got, it again polls for 2 more attempts (i.e)till the timeout value is reached. So if by 3rd attempt the recv string is not recieved, the member will be marked as down.

 

You can have this verified by enabling the monitor logging on the node. The logs will be captured on /var/log/monitors/.
