A Configuration Management Database (CMDB) allows managing Configuration Items (CIs) including identifying, recording, maintaining, controlling, and reporting. CMDB collects and stores the following items as configuration records:

• IT Configuration Items, such as IT Services and their components required for service delivery as Configuration Items; .
• CMDB Class CI Types,  determining determining CI business logic and the set of various attributes;.
• CI Relationships, specifying types of interactionsof interactions, and dependencies between CIs. Follow the CI Relationship link to learn more. 

CMDB records, therefore, describe your CIs with their Relationshipsrelationships, types of dependencies, and various characteristics.

The Service Model visualizes CIs and their relationships with a Dependency Map view view, which demonstrates CIs current statuses and interactions.

CMDB Class Type

Within In the SimpleOne solution,   IT Services are considered as Configuration Items in the SimpleOne solution, along with with the constituent components required for proper service delivery.  The CI The CMDB Class Type selection specifies a set of the CI attributes, its placeits place, and hierarchical position on the Service Model structure.

To identify your CI either as an IT Service or as a custom CI, at first, determine your CIs diversity with the CI Types list that stores the records with type names.

These records keep all detailed information about CIs such as CI Type and , set of attributes with their values depending on it. To identify your CI as an IT Service or as an IT Service component, select the CI Type value from the list and fill in the form. A set of fields on the CI form is different for an IT Service and the CIs of another type, except for the common description fields.

CI Relationships

A CI Relationship describes a connection between two Configuration Items by determining the attributes of this relation.

CI Relationships are represented with single-directional and bi-directional arrows connecting the CIs on the Service Dependency Map.

Push the Dependency Map button Image Removed next to the Source CI or the Recipient CI field to open the Dependency Map view.

CI Relationship direction

Determine an impact direction of the CI Relationship, when choosing a source CI and a recipient one. In case any of the source CI degrades or becomes unavailable, the recipient CI is adversely affected according to the established relationship.

If both source and recipient CIs have this kind of impact on each other, set the Bilateral Relation checkbox active. 

CI Relationship Condition

A negative impact from the Source CI can lead to an immediate degradation of the Recipient CI regardless of the conditions or other supporting Source CIs. The Operational Status Transfer Type with the Unconditional value allows specifying the CI Relationship as an impact. The Relationship weight of this type of connection is equal to 1.

In other cases, Recipient CI status is provided by few Source CIs and should stay active even after the degradation of one them. To apply this kind of CI Relationship, specify the Operational Status Transfer Type with the Conditional value. The Weights of these relationships have the same value - 1/n, where n is their total number.

Add a new CI Relationship

To establish a new CI Relationship, go to the CMDB → CI Relationships menu, and push the New button. Then fill in the form:

Field

Source CI

Operational Status Transfer Type

Choose one of the possible values describing the type of the operational impact:

• Unconditional.

Service Dependency Map

A Service Dependency Map is a Service Model represented by an hierarchical structure of the CIs with an IT Service on the top and their current operational states as coloured marks. 

All CIs related to an IT Service are arranged by hierarchical levels that are determined by CI Types. Since each CI Type defines the hierarchical level of the Service Dependency Map, creating a new type will result in adding a new lower level of this model. 

CIs are presented as model elements with colour-coded frames depending on their current Operational State values. The following table shows colour and state accordance:

CI Relationships are visualized with unidirectional or bidirectional arrows depending on an impact direction. 

Push the Dependency Map button Image Removed next to the Source CI or the Recipient CI field of the CI Relationship to see the hierarchical place of your CI on the Service Dependency map.

Create a CI Relationship

You can add a new CI Relationship from the Dependency Map view. Right-click on the desired CI and choose Create Relationship option in the popup menu, then select one of the possible values:

• Incoming - to create an incoming connection to your CI;
• Outgoing - to create an outgoing connection from your CI. 

Fill in the form of a new CI Relationship and push the Save or Save and Exit button.

Change a CI Operational State

You can change the CI Relationship State right from the Dependency Map view. Right-click on the desired CI and and select Change Operational State option in the popup menu, then, choose one of the possible CI Operational state values:

• Available - CI with this state value are marked with the green frame on the map view;
• Degraded - marks CI with yellow frame;
• Unavailable - marks CI with red frame;
• Maintenance - also marks CI with red frame, as CI is not available while in maintenance state.
