 | <a name="input_cluster_monitoring_interval"></a> [cluster\_monitoring\_interval](#input\_cluster\_monitoring\_interval) | Interval, in seconds, between points when Enhanced Monitoring metrics are collected for the DB cluster. To turn off collecting Enhanced Monitoring metrics, specify 0. Valid Values: 0, 1, 5, 10, 15, 30, 60 | `number` | `0` | no |
-| <a name="input_cluster_performance_insights_enabled"></a> [cluster\_performance\_insights\_enabled](#input\_cluster\_performance\_insights\_enabled) | Valid only for Non-Aurora Multi-AZ DB Clusters. Enables Performance Insights for the RDS Cluster | `bool` | `null` | no |
-| <a name="input_cluster_performance_insights_kms_key_id"></a> [cluster\_performance\_insights\_kms\_key\_id](#input\_cluster\_performance\_insights\_kms\_key\_id) | Valid only for Non-Aurora Multi-AZ DB Clusters. Specifies the KMS Key ID to encrypt Performance Insights data. If not specified, the default RDS KMS key will be used (aws/rds) | `string` | `null` | no |
-| <a name="input_cluster_performance_insights_retention_period"></a> [cluster\_performance\_insights\_retention\_period](#input\_cluster\_performance\_insights\_retention\_period) | Valid only for Non-Aurora Multi-AZ DB Clusters. Specifies the amount of time to retain performance insights data for. Defaults to 7 days if Performance Insights are enabled. Valid values are 7, month * 31 (where month is a number of months from 1-23), and 731 | `number` | `null` | no |
