  • it helps when you explain what you are trying to do and not throw some words at people. so i did a quick google and it suggests you are talking about certain Cisco ACE terms right?

    After the ACE marks a server as failed, it waits a period of time (passdetect interval) and then sends a probe to the failed server. When the ACE receives a successful response and the configured number of consecutive successful responses from the server (passdetect count) is not reached, it uses the passdetect interval and sends another probe.

    When the ACE sends a probe, it waits for the SYN-ACK after sending a SYN to open and then send an ACK to establish the connection with the server. You can configure the time interval for a connection to be established by using the open command

    when looking at the health monitor documentation you should be able to configure something similar with those: https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/ltm-monitors-reference-11-2-0/3.htmlunique_1681579974

    if you poll every 2 seconds and want the server to be directly up with the first succesfull response that is Interval 2 and not other changes. Timeout can be a little lower then.

    Open sounds like Timeout but perhaps is more relaxed. just read the documentation and experiment a little to get it to work to your requirements. and next time just explain the health monitor behaviour you are looking for.
