Link

Link connects two Objects. You can use it to describe and check connection between hosts or services.

Unlike Objects, Links don’t have names or any parents/children, but have direction defined by source from and target to Objects. Otherwise, Links are similar to Objects - they have Data Ingestion, State, Properties, Operations, Tags, etc.
