At the core of Hyperglance is a model that consists of Groups, Resources, Links, Endpoints (interfaces), Tiers and Zones:
Left-clicking on any Entity (Group, Resource, Link or Endpoint) will bring up the entity dashboard.
Tiers and Zones are not considered entities and are not clickable, they simply serve to help organise the other entities.
Groups work like folders in that they organise resources and can be expanded/contracted to show/hide these resources on the diagram. Groups often they relate to cloud concepts such as VPCs, Subnets, Virtual-Networks, etc.
Resources represent devices and other central concepts. They include things like Instances/VMs, Databases, Load balancers, etc.
Links represent connections and associations between resources and/or groups. Links are often purely logical relationships and, if you click them, may not have any information to show. Some important links such as VPC Peering Connections do have interesting data to show. Read more about the various types of links in Hyperglance.
Endpoints are only available on certain nodes such as Instances/VMs and usually represent interfaces e.g. A Network-Interface.
They are accessed via the node's dashboard on the 'ENDPOINTS' tab:
