By default, vCenter discovery is initiated on these ports:

   1. Navigate to AllConfigurationVMwarevCenter.
   2. Select the specific instance from the list of instances.
   3. Edit the URL field to include the port.  
      For example, <kbd class="ph userinput">https://10.0.0.1:444</kbd>
   4. Select Update.

      The VMWare - vCenter Classify probe attempts to establish a connection between the MID Server and the vCenter instance. If the connection is successful, it triggers the VMWare - vCenter Datacenters probe.
