# AWS::ApplicationSignals::ServiceLevelObjective DependencyConfig
<a name="aws-properties-applicationsignals-servicelevelobjective-dependencyconfig"></a>

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

## Syntax
<a name="aws-properties-applicationsignals-servicelevelobjective-dependencyconfig-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-applicationsignals-servicelevelobjective-dependencyconfig-syntax.json"></a>

```
{
  "[DependencyKeyAttributes](#cfn-applicationsignals-servicelevelobjective-dependencyconfig-dependencykeyattributes)" : String,
  "[DependencyOperationName](#cfn-applicationsignals-servicelevelobjective-dependencyconfig-dependencyoperationname)" : String
}
```

### YAML
<a name="aws-properties-applicationsignals-servicelevelobjective-dependencyconfig-syntax.yaml"></a>

```
  [DependencyKeyAttributes](#cfn-applicationsignals-servicelevelobjective-dependencyconfig-dependencykeyattributes): String
  [DependencyOperationName](#cfn-applicationsignals-servicelevelobjective-dependencyconfig-dependencyoperationname): String
```

## Properties
<a name="aws-properties-applicationsignals-servicelevelobjective-dependencyconfig-properties"></a>

`DependencyKeyAttributes`  <a name="cfn-applicationsignals-servicelevelobjective-dependencyconfig-dependencykeyattributes"></a>
If this SLO is related to a metric collected by Application Signals, you must use this field to specify which dependency the SLO metric is related to.  
+ `Type` designates the type of object this is.
+ `ResourceType` specifies the type of the resource. This field is used only when the value of the `Type` field is `Resource` or `AWS::Resource`.
+ `Name` specifies the name of the object. This is used only if the value of the `Type` field is `Service`, `RemoteService`, or `AWS::Service`.
+ `Identifier` identifies the resource objects of this resource. This is used only if the value of the `Type` field is `Resource` or `AWS::Resource`.
+ `Environment` specifies the location where this object is hosted, or what it belongs to.
