Can't see all the monitors

Can anyone tell me why when I go to a node I can't see all the monitors as available? If I create a new one it doesn't always show up there? I am trying to setup an HTTP rule very simple is the page up or not. Can't see it when I try to use it. Thanks in advance! Joe

    Hi Joe,

     

     

    A node is an IP address whereas a pool member is an IP address and port (with an association to the pool name). Normally, you create a monitor for a pool member without an alias IP or port and the monitor inherits the pool member IP and port. A service level monitor without a hardcoded port can't be associated with a node as there isn't a way for the monitoring daemon to know what port to perform the check on. If you create a monitor with a hardcoded alias port, then you can apply it to a node (an IP address).

     

     

    The short answer is that you generally want to associate service monitors with a pool. If you need to create dependencies between multiple ports or multiple IP:ports you can use the alias IP and/or port definitions on the monitor to do so.

     

     

    Hope this is clear? If not, can you describe what you're trying to implement in more detail?

     

     

    Thanks, Aaron
  • If you are running v10, make sure you select the appropriate management partition before you create or search for a monitor. This feature tripped me up quite often when I was first exposed to them.
