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:

• Configuration Items, such as IT as IT Services and their components required for service delivery; .
• CI CMDB Class 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.

Add a new CI Type

To create a new CI Type, navigate follow the steps below:

• Navigate to CMDB → CI Types, and push the New button. 
• Fill in the Name field

• Click the Save or Save and Exit to apply changes.

Created CMDB Class Type appears at the start of the list. Since each Class button. A created CI Type is added to the end of the CI Types list. Since each CI Type defines the hierarchical level of the Service Dependency Map, creating a new one results in adding the next lower level of this the model.

Configuration Item

Create, identify, configure, and manage your CIs and their parameters with the records in the list of the Configuration Items. These Items (sys_cmdb_ci) table. 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.

To add a new configuration item, please complete the steps below:

1. Navigate to the CMDB → Configuration Items.
2. Click New and fill in the fields.

There are two ways to extend the CMDB structure:

• CMDB extension with table inheritance.
• CMDB extension with classes and models

To extend or to customize your CI set of attributes depending on the CI Type, use the CMDB Expansion features.

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 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 CIs 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. 

Operational State Transfer Type

Depending on a Source CI impact the Operational State transfer type of a CI Relationship has two values - Conditional and Unconditional.

Within the Unconditional CI Relationship, degradation or unavailability of the Source CI makes the Recipient CI unavailable under any conditions, regardless of the other circumstances. In this case, the Relationship weight is equal to 1. 

Within the Conditional CI Relationship, the operational state of the Recipient CI is transferred by a few Source CIs with Relationship weights of the same values, in total equal to 1. If a number of the CI Relationships changes, so do their weights.

In the case of the Source CI unavailability, the CI Relationship carries 0 value with the Weight on Change field. If Source CI becomes degraded, the Relationship transfers a half weight.

Thus, a conditional Relationship weight or an unconditional Relationship sum weight provides the operational state of a recipient CI with the following value:

• 0 - makes a recipient CI unavailable;
• 1 - maintains CI availability;
• from 0 to 1 - makes CI degraded.

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

Description

Source CI

Recipient CI

Bilateral Relation

Operational State Transfer Type

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

• Conditional;
• Unconditional.

Relationship Weight

Weight on change

An automatically calculated decimal number, equal to or less than 1. It defines CI Relationship actual weight depending on the Operational Status change.

To save a created CI Relationship record, push the Save or Save and Exit button. 

Service Dependency Map

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

All CIs are arranged by hierarchical levels that are determined by CI Types. Creating a new CI Type results in adding the next 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:

The Service Dependency Map visualizes CI Relationships with simple-directional or bi-directional 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 the 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 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 is 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.
