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

This structure contains the configuration for a composite service level indicator (SLI) that aggregates metrics across multiple operations of a service for service-level SLOs.

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

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

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

```
{
  "[CompositeSliComponents](#cfn-applicationsignals-servicelevelobjective-compositesliconfig-compositeslicomponents)" : {{[ CompositeSliComponent, ... ]}},
  "[SelectionConfig](#cfn-applicationsignals-servicelevelobjective-compositesliconfig-selectionconfig)" : {{SelectionConfig}}
}
```

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

```
  [CompositeSliComponents](#cfn-applicationsignals-servicelevelobjective-compositesliconfig-compositeslicomponents): {{
    - CompositeSliComponent}}
  [SelectionConfig](#cfn-applicationsignals-servicelevelobjective-compositesliconfig-selectionconfig): {{
    SelectionConfig}}
```

## Properties
