Service Dependency Based Deduplication works on the logic that the incidents coming in for a service and its dependencies have a related cause.

Adding a Service Dependency

Adding Dependent services helps the system understand the relationship between your actual systems.

You can add a dependency for your Service by:

• Move over to the Service tab from the left side navigation panel
• Click on the More Option icon and choose Dependencies

• Search and add dependency services from your Squadcast Organization.

In this example above, we have marked the Backend Prometheus Service and Translations services as a dependencies of the Payment Portal service.

This means that the Payment Portal service is dependent on Backend Prometheus Service and Translations

Enabling Service Dependency Based Deduplication

Once you’ve added the Service dependencies, you can set a Service Dependency based deduplication rule which would deduplicate all incoming events for the chosen service against the latest incident of its service dependencies.

To enable this:

• Move over to the Deduplication option from the More Options icon for the chosen service.
• You will see a checkbox with the message as shown in the image below. This checkbox will be disabled by default.
• To enable Service Dependency based deduplication, you can check this and this will hold true for that particular rule.

Enabling Service Dependency Based Deduplication for a Specific Dependency

In cases where you would like the system to consider just one of the many dependencies for a service, you can follow the method below.

Along with enabling the Service Dependency checkbox as shown above, you will need to add the below condition to the rule.

past_incident.service == <slug_of_the_particular_dependency_service>

The slug of a service is displayed on the Service card as shown below.
