Defining CI Relationships

 

CI Relationships form a major part of your CMDB, as it is the relationships between the CIs that differentiate the CMDB from the Asset database. A CMDB without relationships constitutes a bunch of CIs in a single database; fetched through scan or import process, or by manual addition. But with relationships, the users accessing CMDB can understand the inter-dependencies between the CIs, and in the case of a failure, the impact caused on another CI can be identified.

NOTE: To make your CMDB structure less complex, consider the relationships you will require in your CMDB and ensure to use the right relationship type to define the nature of relationship.

Defining Relationships

In order to define the CI relationships in your CMDB, three piece of information is required.

  1. The CI for which the relationship is created

  2. The Type of Relationship denoting the inter-dependencies between the CIs, and

  3. The dependent CI.

For example, consider a sentence like "ServiceDeskServer Depends on CentOS2Server". Here, ServiceDeskServer is the CI for which the relationship is created, Depends on denotes the nature of relationship, and CentOS2Server forms the dependent CI.

Each CI in ManageEngine ServiceDesk Plus is represented with Attributes and Relationships. The Attributes are data elements that describe the characteristics of the CIs.
