Amazon CloudWatch dimensions for Amazon RDS
You can filter Amazon RDS metrics data by using any dimension in the following table.
| Dimension | Filters the requested data for . . . |
|---|---|
DBInstanceIdentifier
|
A specific DB instance. |
DatabaseClass
|
All instances in a database class. For example, you can aggregate metrics for all instances
that belong to the database class |
EngineName
|
The identified engine name only. For example, you can aggregate metrics for all instances that have the engine name
|
SourceRegion
|
The specified Region only. For example, you can aggregate metrics for all DB instances in
the |
DbInstanceIdentifier, VolumeName
|
The metrics per-volume for a single instance. RDS captures metrics for multiple storage volumes. |
Note
If you are using additional storage volumes, you can see aggregate storage metrics under
the DBInstanceIdentifier dimension. To see per-volume storage metrics, use the
DbInstanceIdentifier, VolumeName dimensions.
For Multi-AZ DB clusters, Amazon RDS publishes metrics for each DB instance in the cluster under the
DBInstanceIdentifier dimension. Metrics aren't available under a DB cluster dimension such as
DBClusterIdentifier.
To monitor a Multi-AZ DB cluster, view the metrics for each DB instance in the cluster. To create an alarm that evaluates all of the DB instances in the cluster, use a metric math expression. For an example, see Tutorial: Creating an Amazon CloudWatch alarm for Multi-AZ DB cluster replica lag for Amazon RDS.
