<a name="estimate_consumption_cw"></a>

To estimate and monitor read and write capacity consumption, you can use a CloudWatch dashboard. For more information about available metrics for Amazon Keyspaces, see [Amazon Keyspaces metrics and dimensions](metrics-dimensions.md). 

To monitor read and write capacity units consumed by a specific statement with CloudWatch, you can follow these steps.

1. Create a new table with sample data

1. Configure a Amazon Keyspaces CloudWatch dashboard for the table. To get started, you can use a dashboard template available on [Github](https://github.com/aws-samples/amazon-keyspaces-cloudwatch-cloudformation-templates).

1. Run the CQL statement, for example using the `ALLOW FILTERING` option, and check the read capacity units consumed for the full table scan in the dashboard.
