Viewing the system taxonomy

The system taxonomy defines all kinds of data objects in the system and the relationships between them. The BMC Helix Discovery Administrator can examine all of these objects, including their attributes, roles, and relationships.

None of this information can be changed from the BMC Helix Discovery user interface.

To view the system taxonomy

  1. From the main menu, click the Administration icon 
    The Administration page opens.
  2. In the Model section, click View Taxonomy.
    All base taxonomy objects are listed, along with the following information:
    • Object Name—The name of the object kind. The superclass of this object is displayed in brackets as a hyperlink.
    • Description—A description of this object type.
    • Subclasses—Subclasses of this object type.
    • Attributes—Attributes of this object type.
    • Known relationships—Known relationships for this object. The object to which this relationship refers is displayed as a hyperlink at the end of the relationship name. Relationships with impact information also display arrows denoting the impact direction. For example:
      •  Contained:Containment:Container:Cluster [Cluster]
        Containing Cluster
      •  Container:Containment:Contained:ClusterMember [Cluster Members]
        Cluster Members contained in this Cluster

The Files tab shows the taxonomy files that are installed on the appliance, and download links to those files. From the Files tab, click the link to the 00taxonomy to download the base taxonomy, or links to other taxonomy extensions that you have installed. The download is a zip file of directories containing the JSON files that make up the taxonomy.

Further details of the data model can be found in the BMC Helix Discovery taxonomy. To view the taxonomy on the BMC Helix Discovery UI, from the main menu, click the Administration iconThe Administration page displays. From the Model section, click View Taxonomy. A link to the current, full-size version of the diagrams below is also available in the online documentation.

Taxonomy limitation

The relationships displayed in the taxonomy are not exhaustive. That is, all possible relationships are not displayed in the taxonomy.
For example, the following containment relationships are valid:

  • Group:Container:Containment:ContainedItem:SoftwareInstance
  • Group:Container:Containment:ContainedItem:Host

The following diagrams show the BMC Helix Discovery Default Data Model with its different nodes, attributes and relationships between different parts of BMC Helix Discovery. It is split across the following diagrams:

  • Main Diagram—contains all the core entities used in the modeling and discovery of hosts.
  • Network and Printer Diagram—contains entities used in the modeling and discovery of network devices and printers.
  • Mainframe Diagram—contains entities used in the modeling and discovery of mainframe computers.
  • Storage and Load Balancers—contains entities used in the modeling and discovery of storage entities and load balancers.

It is important to note that the model itself is not in separate sections, the separate diagrams exist in order to more clearly convey information.

Storage and Load Balancers

You can also download a pdf file here which includes all of the diagrams above, and provides a better zoom capability than the individual PNG files.

The PNG images are static and represent the latest taxonomy.

The Telco taxonomy extension

A Telco taxonomy extension is provided for users of BMC Helix for CSP, the IT service management platform for telecommunication service providers. The taxonomy extension simply provides a model for BMC Helix for CSP to use. BMC Helix Discovery does not populate or modify this model in any way. To enable the Telco taxonomy extension, see Telco nodes.
