Relational Database Service Cluster (AWS_RDS_CLUSTER)
Attributes (parameters)
The following attributes are available for this monitor type:
Name | Description | Unit | Default Performance Key Indicator (KPI) |
---|---|---|---|
Aurora Global DB Data Transfer Bytes (AuroraGlobDBDataTransBytes) | In an Aurora Global Database, the amount of redo log data transferred from the master AWS Region to a secondary AWS Region. | MB | No |
Aurora Global DB Replication Lag (AuroraGlobalDBReplicated) | In an Aurora Global Database, the number of write I/O operations replicated from the primary AWS Region to the cluster volume in a secondary AWS Region. The billing calculations for the secondary AWS Regions in a global database use VolumeWriteIOPS to account for writes performed within the cluster. The billing calculations for the primary AWS Region in a global database use VolumeWriteIOPS to account for the write activity within that cluster, and AuroraGlobalDBReplicated to account for cross-Region replication within the global database. | MB | No |
Backup Retention Period Storage Used (BackRetePeriodStorageUsed) | The total amount of backup storage used to support the point-in-time restore feature within the Aurora DB cluster's backup retention window. This amount is included in the total reported by the TotalBackupStorageBilled metric. It is computed separately for each Aurora cluster. | MB | No |
BacktrackChangeRecordsCreationRate (BacktrChaReCrRate) | The number of backtrack change records created over 5 minutes for your DB cluster. | Count/Second | No |
Backtrack Change Records Stored (BacktrkChangeRecStored) | The number of backtrack change records used by your DB cluster. | Count | No |
DB Cluster Status (DBClusterStatus) | The status of a DB cluster indicates the health of the DB cluster. | 0 - available 1 - inaccessible-encryption-credentials,migration-failed 2 - others | No |
Serverless Database Capacity (ServerlessDatabaseCapacity) | The current capacity of an Aurora Serverless v1 DB cluster. | Count | No |
Snapshot Storage Used (SnapshotStorageUsed) | The total amount of backup storage consumed by all Aurora snapshots for an Aurora DB cluster outside its backup retention window. This amount is included in the total reported by the TotalBackupStorageBilled metric. It is computed separately for each Aurora cluster. | MB | No |
Total Backup Storage Billed (TotalBackupStorageBilled) | The total amount of backup storage in bytes for which you are billed for a given Aurora DB cluster. The metric includes the backup storage measured by the BackupRetentionPeriodStorageUsed and SnapshotStorageUsed metrics. This metric is computed separately for each Aurora cluster. | MB | No |
Volume Bytes Used (VolumeBytesUsed) | The amount of storage used by your Aurora DB instance. This value doesn't reflect some internal storage allocations that don't affect storage billing. Thus, you can anticipate out-of-space issues more accurately by testing whether AuroraVolumeBytesLeftTotal is approaching zero instead of comparing VolumeBytesUsed against the storage limit of 128 TiB. | MB | No |
Volume Read IOPs (VolumeReadIOPs) | The number of billed read I/O operations from a cluster volume within a 5-minute interval. Billed read operations are calculated at the cluster volume level, aggregated from all instances in the Aurora DB cluster, and then reported at 5-minute intervals. The value is calculated by taking the value of the Read operations metric over a 5-minute period. You can determine the amount of billed read operations per second by taking the value of the Billed read operations metric and dividing by 300 seconds. For example, if the Billed read operations returns 13,686, then the billed read operations per second is 45 (13,686 / 300 = 45.62). You accrue billed read operations for queries that request database pages that aren't in the buffer cache and must be loaded from storage. You might see spikes in billed read operations as query results are read from storage and then loaded into the buffer cache. | Count/Second | No |
Volume Write IOPs (VolumeWriteIOPs) | The number of write disk I/O operations to the cluster volume, reported at 5-minute intervals. For a detailed description of how billed write operations are calculated, see VolumeReadIOPs. | Count/Second | Yes |
