Not sure where the confusion is? As long as the central server has
access to the subnets that your leaf nodes reside on, it can actively
monitor those nodes services.

If the central server cannot "reach" the leaf nodes, perhaps you may
want the slave servers actively monitoring the leaf nodes, and
forwarding those results as well up to the central server.
