# AWS usage metrics
CloudWatch collects metrics that track the usage of some AWS resources and APIs. These metrics are published in the `AWS/Usage` namespace. Usage metrics in CloudWatch allow you to proactively manage usage by visualizing metrics in the CloudWatch console, creating custom dashboards, detecting changes in activity with CloudWatch anomaly detection, and configuring alarms that alert you when usage approaches a threshold.
Some AWS services integrate these usage metrics with Service Quotas. For these services, you can use CloudWatch to manage your account's use of your service quotas. For more information, see [Visualizing your service quotas and setting alarms](CloudWatch-Quotas-Visualize-Alarms.md).

# Visualizing your service quotas and setting alarms
For some AWS services, you can use the usage metrics to visualize your current service usage on CloudWatch graphs and dashboards. You can use a CloudWatch metric math function to display the service quotas for those resources on your graphs. You can also configure alarms that alert you when your usage approaches a service quota. For more information about service quotas, see [What Is Service Quotas](https://docs.aws.amazon.com/servicequotas/latest/userguide/intro.html) in the *Service Quotas User Guide*.
If you are signed in to an account that is set up as a monitoring account in CloudWatch cross-account observability, you can use that monitoring account to visualize service quotas and set alarms for metrics in the source accounts that are linked to that monitoring account. For more information, see [CloudWatch cross-account observability](CloudWatch-Unified-Cross-Account.md).

**To visualize a service quota and optionally set an alarm**
1. Open the CloudWatch console at [https://console.aws.amazon.com/cloudwatch/](https://console.aws.amazon.com/cloudwatch/).
1. In the navigation pane, choose **Metrics**.
1. On the **All metrics** tab, choose **Usage**, and then choose **By AWS Resource**.
The list of service quota usage metrics appears.
1. Select the check box next to one of the metrics.
The graph displays your current usage of that AWS resource.
1. To add your service quota to the graph, do the following:
1. Choose the **Graphed metrics** tab.
1. Choose **Math expression**, **Start with an empty expression**. In the new row, under **Details**, enter **SERVICE\$1QUOTA(m1)**.
A new line is added to the graph, displaying the service quota for the resource represented in the metric.
1. To see your current usage as a percentage of the quota, add a new expression or change the current **SERVICE\$1QUOTA** expression. The new expression to use is **m1/SERVICE\$1QUOTA(m1)\$1100**.
1. (Optional) To set an alarm that notifies you if you approach the service quota, do the following:
1. On the row with **m1/SERVICE\$1QUOTA(m1)\$1100**, under **Actions**, choose the alarm icon. It looks like a bell.
The alarm creation page appears.
1. Under **Conditions**, ensure that **Threshold type** is **Static** and **Whenever Expression1 is** is set to **Greater**. Under **than**, enter **80**. This creates an alarm that goes into ALARM state when your usage exceeds 80 percent of the quota.
1. Choose **Next**.
1. On the next page, select an Amazon SNS topic or create a new one, and then choose **Next**. The topic you select is notified when the alarm goes to ALARM state.
1. On the next page, enter a name and description for the alarm, and then choose **Next**.
1. Choose **Create alarm**.
# AWS API usage metrics
Most APIs that support AWS CloudTrail logging also report usage metrics to CloudWatch. API usage metrics in CloudWatch allow you to proactively manage API usage by visualizing metrics in the CloudWatch console, creating custom dashboards, detecting changes in activity with CloudWatch anomaly detection, and configuring alarms that alert when usage approaches a threshold.
You can use the he following table to learn about services that report API usage metrics to CloudWatch. The table lists the values to use for the `Service` dimension, so you can see the usage metrics from that service. You can use the procedure in this section to view the list of a service's APIs that report usage metrics to CloudWatch.

Some services report usage metrics for additional APIs as well. To see whether an API reports usage metrics to CloudWatch, use the CloudWatch console to see the metrics reported by that service in the `AWS/Usage` namespace.
**To see the list of a service's APIs that report usage metrics to CloudWatch**
1. Open the CloudWatch console at [https://console.aws.amazon.com/cloudwatch/](https://console.aws.amazon.com/cloudwatch/).
1. In the navigation pane, choose **Metrics**.
1. On the **All metrics** tab, choose **Usage**, and then choose **By AWS Resource**.
1. In the search box near the list of metrics, enter the name of the service. The metrics are filtered by the service you entered.
# CloudWatch usage metrics
CloudWatch collects metrics that track the usage of some AWS resources. These metrics correspond to AWS service quotas. Tracking these metrics can help you proactively manage your quotas. For more information, see [Visualizing your service quotas and setting alarms](CloudWatch-Quotas-Visualize-Alarms.md). Service quota usage metrics are in the `AWS/Usage` namespace and are collected every minute.
The metrics that can be published in this namespace include `CallCount`, `ResourceCount`, and `ThrottleCount`. These metrics are published with the dimensions `Resource`, `Service`, and `Type`. The `Resource` dimension specifies the name of the API operation being tracked. For example, the `CallCount` metric with the dimensions `"Service": "CloudWatch"`, `"Type": "API"` and `"Resource": "PutMetricData"` indicates the number of times the CloudWatch `PutMetricData` API operation has been called in your account.
The `CallCount` metric does not have a specified unit. The most useful statistic for the metric is `SUM`, which represents the total operation count for the 1-minute period.
**Metrics**
| Metric | Description |
| --- | --- |
| `CallCount` | The number of specified operations performed in your account. |
**Dimensions**
| Dimension | Description |
| --- | --- |
| `Service` | The name of the AWS service containing the resource. For CloudWatch usage metrics, the value for this dimension is `CloudWatch`. |
| `Class` | The class of resource being tracked. CloudWatch API usage metrics use this dimension with a value of `None`. |
| `Type` | The type of resource being tracked. When the `Service` dimension is `CloudWatch`, the only valid value for `Type` is `API`. |
| `Resource` | The name of the API operation. Valid values include the following: DeleteAlarms, DeleteDashboards, DescribeAlarmHistory, DescribeAlarms, GetDashboard, GetMetricData, GetMetricStatistics, ListMetrics, PutDashboard, and PutMetricData |
