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

This structure contains information about the performance metric that a request-based SLO monitors.

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

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

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

```
{
  "[ComparisonOperator](#cfn-applicationsignals-servicelevelobjective-requestbasedsli-comparisonoperator)" : String,
  "[MetricThreshold](#cfn-applicationsignals-servicelevelobjective-requestbasedsli-metricthreshold)" : Number,
  "[RequestBasedSliMetric](#cfn-applicationsignals-servicelevelobjective-requestbasedsli-requestbasedslimetric)" : RequestBasedSliMetric
}
```

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

```
  [ComparisonOperator](#cfn-applicationsignals-servicelevelobjective-requestbasedsli-comparisonoperator): String
  [MetricThreshold](#cfn-applicationsignals-servicelevelobjective-requestbasedsli-metricthreshold): Number
  [RequestBasedSliMetric](#cfn-applicationsignals-servicelevelobjective-requestbasedsli-requestbasedslimetric): 
    RequestBasedSliMetric
```

## Properties

`ComparisonOperator`  <a name="cfn-applicationsignals-servicelevelobjective-requestbasedsli-comparisonoperator"></a>
The arithmetic operation used when comparing the specified metric to the threshold.  
*Required*: No  
*Type*: String  
*Allowed values*: `GreaterThanOrEqualTo | LessThanOrEqualTo | LessThan | GreaterThan`  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`MetricThreshold`  <a name="cfn-applicationsignals-servicelevelobjective-requestbasedsli-metricthreshold"></a>
This value is the threshold that the observed metric values of the SLI metric are compared to.  
*Required*: No  
*Type*: Number  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`RequestBasedSliMetric`  <a name="cfn-applicationsignals-servicelevelobjective-requestbasedsli-requestbasedslimetric"></a>
A structure that contains information about the metric that the SLO monitors.   
*Required*: Yes  
*Type*: [RequestBasedSliMetric](aws-properties-applicationsignals-servicelevelobjective-requestbasedslimetric.md)  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)
