# Assessment metrics
<a name="next-gen-assessment-metrics"></a>

The following metrics are emitted after each successful failure mode assessment. One data point is published per policy component that has assessment results.


| Metric | Dimensions | Description | Values | 
| --- | --- | --- | --- | 
| PolicyAchievable | Service, PolicyComponent=AvailabilitySlo | Whether your availability SLO target is achievable. | 1.0 or 0.0 | 
| PolicyAchievable | Service, PolicyComponent=MultiAzRtoRpo | Whether your multi-AZ RTO and RPO targets are achievable. | 1.0 or 0.0 | 
| PolicyAchievable | Service, PolicyComponent=MultiRegionRtoRpo | Whether your multi-Region RTO and RPO targets are achievable. | 1.0 or 0.0 | 

The following table describes the metric dimensions.


| Dimension | Description | 
| --- | --- | 
| Service | The name of the service being assessed. | 
| PolicyComponent | The resilience policy component being evaluated. Possible values: AvailabilitySlo, MultiAzRtoRpo, MultiRegionRtoRpo. | 

**Note**  
Only policy components for which the assessment produces an achievability result are emitted.

Use the `Minimum` statistic when creating alarms on this metric. A `Minimum` of 0.0 indicates that at least one assessment found the policy not achievable during the evaluation period.
