Working with Performance Metrics in the Amazon
CloudWatch Console
When working with Amazon Redshift metrics in the Amazon CloudWatch console, there are couple of
things you should keep in mind:
• Query and load performance data is only available in the Amazon Redshift console.
• Some Metrics in the Amazon CloudWatch have different units than those used in the Amazon Redshift
console. For example, WriteThroughput, is displayed in GB/s (as compared to Bytes/s in Amazon
CloudWatch) which is a more relevant unit for the typical storage space of a node.
When working with Amazon Redshift metrics in the Amazon CloudWatch console, command line tools,
or an Amazon SDK, there are two concepts to keep in mind.
• First, you specify the metric dimension to work with. A dimension is a name-value pair that helps you
to uniquely identify a metric. The dimensions for Amazon Redshift are ClusterIdentifier and
NodeID. In the Amazon CloudWatch console, the Redshift Cluster and Redshift Node views
are provided to easily select cluster and node-specific dimensions. For more information about
dimensions, see Dimensions in the Amazon CloudWatch Developer Guide.
• Second, you specify the metric name, such as ReadIOPS.
The following table summarizes the types of Amazon Redshift metric dimensions that are available to
you. All data is available in 1-minute periods at no charge.
