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 interdependencies 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 interdependencies between the CIs, and

    3. The dependent CI.

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



    Accessing the Relationship Tab


    Every CI in ManageEngine AssetExplorer is represented with Attributes and Relationship. While the Attributes are data elements describing the CIs, the relationships help in understanding the interdependencies between the CIs. The relationships can be defined from the relationship tab.


    To access the Relationships tab,

    1. Click CMBD tab in the header pane.

    2. Select the CI Type from the Configuration Items block. Say, Workstation. Else, select All CIs link to view all the CIs irrespective of the CI Type.

    3. Select the CI Name link to view the CI details.

    4. From the CI details page, click Relationships sub-tab.


    Viewing relationships from the Relationship tab


    The relationship between the CIs are viewed in the Relationship tab. From the Relationship tab, you can

    • View the Relationships in Map View and List View

    • Access the full screen of the Relationship Map

    • Zoom in and Zoom out the relationships linked in the map

    • Add Relationships

      You can also view CIs under a specific CI Type. Select the CI Type from the drop-down, say, Department. The CIs available for the CI Type Department are listed under Available CI(s) column.
