How are models organized?

In the Data dashboard, the top-level nodes are based on root queries. The entries that appear in the Data tree are instances of the types defined in the data model. Thus, not all defined types appear, but only those types for which Agents have created at least one instance.

These queries are defined in modules and they use the module name as the node name. There are several nodes that are always present because they are root queries defined in the Management Server. Other nodes may be present. They originate from root queries defined in cartridges that have been installed on the Management Server.

Some examples are:

•
Alarms — Current Alarms and Outstanding Alarms
•
Hosts — All Hosts
•
Management Server — All Agents, All Data, Schema, and Servers
•
Services — All Model Roots, All Object Groups, All Service Categories, All Services, and All System Services
•
Other nodes, depending on the cartridges that have been installed

For example, the common Host model is a topology model defined in the Management Server to describe the host objects being monitored. The use of a common model allows the Management Server to provide out-of-the-box configuration for visualizing hosts that could be monitored by any type of agent.

Where can I see the data model hierarchy?

All data models have a root. In the Management Server’s user interface, Dashboards > Configuration > Data > Management Server > All Data is considered the root (“/”) in the dashboard framework. The All Data node contains references to the ModelRoot topology instances. A data object shows up under Management Server > All Data if it is defined in topology-types.xml file.

While it is possible for a cartridge to add a root property by explicitly defining the property in the cartridge’s topology-types.xml file, changing types in this way is not encouraged. It is better for the cartridge to provide a new model root, so that a property is added automatically.

The cartridge can do this by defining a topology type in its schema that extends the core "ModelRoot" type. For example:

<type name="MyModelRoot" extends="ModelRoot">

When the new root type is created, the server automatically adds a corresponding property to the Root type that returns instances of that model root. The cartridge then needs to create a single instance of that type and reference the top-level domain objects. The topology types used for top-level domain objects should be annotated with the core "DomainRoot" annotation, so that they can be configured with the admin grouping functionality. For more information about domains, see the What are domains? topic.

For example:

<type name="MyModelRoot" extends="ModelRoot">
  <property name="topLevelObjects" type="MyTopLevelObject" is-many="true"/>
</type>
<type name="MyTopLevelObject" extends="TopologyObject">
  <annotation name="DomainRoot"/>
</type>

What internal models are created?

The Management Server builds internal models for its own activities.

Table 2. Management Server internal models
Model Name
Description
Alarms
Contains all alarms.
All Type Instances
Contains a hierarchy of types with instances; similar to schema browser.
FSMServers, FSMDatabases
Contains the internal Management Server and database models for self-monitoring.
Model Summary
Collects metrics on all models in Model Roots.

What other models are created?

 

Table 3. Other models created
Model Name
Description
AgentMap
Contains all agents.
FSMServiceRoot
Contains the service model.
ServiceLevelPolicies
Contains all service level policy objects.
