Are you using the default HTTP monitor or custom one? There is an option called "Reverse" which reverses the logic of the monitor. This option is off by default; so if you are using the default monitor, it shouldn't be an issue.

 

What do you mean by "server down"? Do you mean, literally down; powered off? Maybe your server is up because the logic in your monitor is wrong.

    Sorry, The explanation was insufficient.

     

    For the pool, only applicable HTTPmonitor is applied. Also, "Reverse" is OFF.

     

    Normally, you can monitor the service normally Although I stopped IIS on the server at one time, the health check remained green.

     

    When I stopped the service of worldwideweb, we switched to red.

     

    Although IIS is down and there should not be a response from the server, an incomprehensible event occurred that became green.

     

    It is not reproducible and dumpFile at the time of event occurrence can not be obtained.
