Does your Management Service exist? Does the Host Monitor Role in the Management Service exist? Is it started? Is there an error in the Host Monitor logs?

 

Normally the initial wizard in CM will guide you through setting up the Management service. Did you skip this wizard?

From the home page, there should be a button in the upper right of your screen to add the management service. It only appears if no management service exists.
