Monitor the performance of a pre-warmed table using Amazon CloudWatch
Amazon Keyspaces pre-warming doesn't introduce new CloudWatch metrics, but you can monitor the performance of pre-warmed tables using existing Amazon Keyspaces metrics:
- SuccessfulRequestLatency
-
Monitor this metric to verify that the pre-warmed table is handling requests with expected latency.
- WriteThrottleEvents and ReadThrottleEvents
-
These metrics should remain low for a properly pre-warmed table. If you see insufficient capacity errors despite pre-warming, you might need to adjust your warm-throughput values.
- ConsumedReadCapacityUnits and ConsumedWriteCapacityUnits
-
These metrics show the actual consumption of capacity, which can help validate if your pre-warming configuration is appropriate.
- ProvisionedReadCapacityUnits and ProvisionedWriteCapacityUnits
-
For provisioned tables, these metrics show the currently allocated capacity.
These metrics can be viewed in the CloudWatch console or queried using the CloudWatch API. For more information, see Monitoring Amazon Keyspaces with Amazon CloudWatch.
