 This construct provides an Amazon CloudWatch dashboard to monitor metrics on Amazon Bedrock models usage. The specific list of metrics created by this construct is available [here](#default-properties).
 
-> **Note:** Native metrics for Amazon Bedrock don't support dimensions beyond model ID. If a single account is hosting multiple workloads in the same region, the Bedrock metrics would be aggregated across all workloads.
+These metrics can be used for a variety of use cases including:
+
+- Comparing latency between different models using the InvocationLatency metric with ModelId dimension
+- Measuring token count (input & output) to assist in purchasing provisioned throughput by analyzing the InputTokenCount and OutputTokenCount
+- Detecting and alerting on throttling with an CloudWatch Alarm with the InvocationThrottles metric
+
+For a specific model, if input/output tokens cost is specified, a widget with on-demand input and total tokens cost will be added. Please refer to the [Amazon Bedrock Pricing page](https://aws.amazon.com/bedrock/pricing/) for details about pricing.
