You can manually link two application services by adding a reference to one application service into another application service. The service that contains the reference, becomes a dependent service. The service that you include as a reference is a contained service. You can link application services to create dependencies for impact monitoring in Event Management.
Before you begin
Ensure that you know the name and the service type of the application service, to which you want to add a reference.
Role required: app_service_admin or service_mapping_adminAbout this task
To create a link, add a reference to the relevant application service as an outgoing connection of the relevant CI inside another application service. For example, you can add the UK Portal application service as a link to the Online Store application service. In this case, the Online Store service becomes dependent on the UK Portal service that it contains. The Online Store service reflects discovery errors for its contained service in the Edit map mode, as well as alerts in Event Management.
When you link an application service to another application service, the information about the CI, to which you linked the service, is updated in the CMDB. The CMDB recognizes other application services that use the same applicative flow, and adds the contained application service to these application services by analogy. The same logic applies when you remove a contained application service: The system removes it from all application services where you either manually linked this service or the system linked this service by analogy.
- A dependency between two application services.
- A placeholder for a map branch that Service Mapping failed to discover. If you create or customize a pattern to discover the configuration item (CI) serving as an entry point for the contained service instance, Service Mapping can discover this contained service.
- An indication that an service instance contains a branch, which Service Mapping cannot discover.
You can add an service instance as a contained service to as many service instance as necessary.
