add the service template for the diskspace with necessary commands as following image

== How to check files ==

== How to add an Agent==

Agent settings are not available for modification directly on a host object. This requires you to create an “Icinga Agent” template. You could name it exactly like that; it’s important to use meaningful names for your templates.
