It is important to create associations that describe the nature of the relationship between two or more CIs. For example, if a network router has an interruption of service, then all servers and PCs connected to that router will also experience an interruption of service. CI dependencies between the router and all servers and PCs connected to it helps you in understanding the impact of the interruption of service.
Dependencies relate to the relationships between CIs and how CIs are connected with one another. Each relationship has a forward and inverse dependency.
Create a custom dependency
Click the blue plus sign and complete the requested information (mandatory fields are marked with an *):
- Name*: Dependency name (e.g. Utilization, Consumption, Installation)
- Forward Dependency*: Name of the forward direction of the dependency (for example, Utilizes, Consumes, Deploys). This value will be displayed when attaching CIs together.
- Inverse Dependency*: Name of the inverse direction of the dependency (for example, Is Utilized By, Is Consumed By, Is Deployed By). This value will be displayed when attaching CIs together.
- Description: A short description of the dependency for internal usage and documentation.
Attach a dependency to a CI
Navigate to Service Desk > CMDB and select a CI.
Click on the CI name in the Configuration Items index and enter the relevant information in the right pane.
Click Attach to create the association.
You will be prompted to select the dependency type and then the configuration item(s) to attach to the current CI.
You can choose to deactivate a dependency to ensure users will not attach CIs of that type.
Delete a Dependency
To delete a dependency, select the CI type and edit out any relationship that is no longer relevant.
