Viewing the system taxonomy

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

None of this information can be changed from the BMC 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.

The Files tab shows the taxonomy files that are installed on the appliance. You can download the base taxonomy in XML format. To do this, from the Files tab, click the 00taxonomy.xml link.

Further details of the data model can be found in the BMC Discovery taxonomy. To view the taxonomy on the BMC 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 Discovery Default Data Model with its different nodes, attributes and relationships between different parts of BMC 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.


Network and Printer


Storage and Load Balancers

You can also download a pdf file here which includes all of the diagrams above.

The PNG images are static and represent the latest taxonomy.They do not reflect any on-site changes that might have been made to the taxonomy on your appliance.

Storage and modification of the taxonomy

Taxonomy definitions are configured using xml files which are held in the following directories:

  1. /usr/tideway/data/installed/taxonomy/
  2. /usr/tideway/data/custom/taxonomy/

The directories are parsed in the order given (installed before custom), and the files contained in these directories are parsed in alphabetical order, with numbers before letters. This order is important as later definitions for the taxonomy override those loaded earlier.

The standard base taxonomy file is contained in /usr/tideway/data/installed/taxonomy/00taxonomy.xml

To add additional details to a node, you should use a detail node rather than extending the taxonomy. For more information, see Detail node.
