When a Monitor has an alias port defined and is applied to a GTM Pool that has a GTM virtual server that has a translated address, the monitor will always fail and mark that pool member down.
The monitor fails, and the virtual server is marked down
This occurs on a GTM virtual server that has a translated address and a monitor with an explicit port (that differs from the virtual server's port).
If possible, deploy a monitor that does not have a port defined. Otherwise there is no workaround available.
GTM now correctly include all information necessary for the monitor to make the correct determination of status.
