# DependencyConfig
<a name="API_DependencyConfig"></a>

Identifies the dependency using the `DependencyKeyAttributes` and `DependencyOperationName`.

When creating a service dependency SLO, you must specify the `KeyAttributes` of the service, and the `DependencyConfig` for the dependency. You can specify the `OperationName` of the service, from which it calls the dependency. Alternatively, you can exclude `OperationName` and the SLO will monitor all of the service's operations that call the dependency.
