CMDB extension feature allows you to manage Configuration Items (CIs): add to your CMDB structure classes of CIs and equipment models specific to these classes. Add special attributes to classes and models to define up-to-date information about assets and equipment.
The picture below illustrates the CMDB structure:
CMDB collects and stores the following items as configuration records:
- CMDB Classes are groups of CIs based on their parameters.
- CMDB Models are composite templates of CI parameters.
- Configuration Items are IT Services and their components required for service delivery.
Role required: cmdb_manager.
CMDB Class
Classes are logical combinations of CIs with similar functions, parameters, and characteristics. Class attributes are the collections of the REM attributes for the Configuration Items (sys_cmdb_ci) table.
- One of the collections contains non-editable attributes − static for all CIs of a specific class.
- The other collection contains editable ones, which can be changed during the CI exploitation.
To add a new class, please perform the following steps:
- Navigate CMDB → CMDB Class.
- Click New and fill in the fields.
- Click Save or Save and Exit to apply changes.
| Field | Mandatory | Description |
|---|---|---|
| Name | Y | Specify the CMDB class name. |
| Description | N | Type detailed description of the class. |
Parent CMDB class | N | Define a parent class for the class. You can choose only classes that are higher in the hierarchy or are not in the hierarchy. |
| Icon | N | Specify the icon for the class by attaching it from your device. |
After the class record is saved, two UI Actions are available on the form:
- Create model attribute – the action opens the modal window that allows for creating model attributes.
- Create CI attribute – the action opens a modal window that allows for creating CI attributes.
In the Related Lists area, you can see models, CIs, model attributes, CI attributes, and child classes related to the record.
If you need to set up choice options for a created attribute, you should go to the attribute record and create choice options in the Related Lists area.
CMDB Model
Models are compound templates of CI parameters. They define specific CIs features. Each class has its list of models.
For CMDB models, the Record Extended Model is used. Attribute values of REM are model parameters. Models include all non-editable attributes of collections from all class levels. The base values of model parameters are the default values of attribute collections and their constituents.
To create a model, please complete the steps below:
- Navigate CMDB → CMDB Model.
- Click New and fill in the fields.
- Click Save or Save and Exit to apply changes.
As a result, the model is created. The model's name consists of the Vendor field value and the Identifier field value.
The CI tab displays all related CIs to the model record in the Related Lists area.
Configuration Item
Create, identify, configure, and manage your CIs and their parameters within the Configuration Items (sys_cmdb_ci) table. The table records keep detailed information about CIs such as a set of attributes with their values, CIs characteristics, model attributes.
To add a new Configuration Item, please complete the steps below:
- Navigate to the CMDB → Configuration Items.
- Click New and fill in the fields.
Click Save or Save and Exit to apply changes.
