# IVS Service Quotas \$1 Low-Latency Streaming
Service QuotasService Quotas

In the "API Call Rate Quotas" table, we added `StartViewerSessionRevocation` and `BatchStartViewerSessionRevocation`. (These are not new endpoints but were missing from the table.) They are in the same part of the table as the playback-key-pair endpoints; the **Endpoint Type** is "Private channel."Service Quotas

Clarified that all quotas are enforced per region.Service Quotas

Increased some Chat quotas:
+ TPS for CreateChatToken, DeleteMessage, DisconnectUser, and SendEvent Rooms
+ Other Quotas: concurrent chat connections; rate of DeleteMessage, DisconnectUser, and SendMessage requests; rate of messaging requests per connection; and RoomsAmazon IVS Service Quotas

For the PutMetadata endpoint, added a limit of 155 TPS per account.Amazon IVS Service Quotas

Minor wording changes. Deleted information about maximum number of tags; this was moved to the API Reference.Amazon IVS Service Quotas

Increased three limits: number of channels, concurrent viewers, and concurrent broadcasts.Amazon IVS Service Quotas

Corrected this to indicate that only the channels, concurrent viewers, and concurrent broadcasts quotas can be adjusted.

The following are service quotas and limits for Amazon Interactive Video Service (IVS) endpoints, resources, and other operations. Service quotas (also known as limits) are the maximum number of service resources or operations for your AWS account. That is, these limits are per AWS account, unless noted otherwise in the table. Also see [AWS Service Quotas](https://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html).

You use an endpoint to connect programmatically to an AWS service. Also see [AWS Service Endpoints](https://docs.aws.amazon.com/general/latest/gr/rande.html).

All quotas are enforced per region.

**Important:** All accounts have limits on the number of concurrent views and concurrent streams. (A *view* is a unique viewing session which is actively downloading or playing video. For a more detailed definition, see the [IVS Glossary](ivs-glossary.md).) *Ensure that your limits are adequate and request an increase if needed, especially if you are planning a large streaming event*. 

## Service Quota Increases


For quotas that are adjustable, you can request a rate increase through the [AWS console](https://console.aws.amazon.com/servicequotas/). Use the console to view information about service quotas too.

API call rate quotas are not adjustable.

For IVS Chat quotas, added quota for "rate of SendMessage requests per room" and clarified that the existing rate quota for SendMessage requests applies across all your rooms.Service Quotas

Added call-rate quotas for GetStreamSession and ListStreamSessions. (These IVS endpoints were added previously, when Stream Health was launched.)

## Service Quotas Integration with CloudWatch Usage Metrics
Amazon IVS Service Quotas

Added a new section, "Service Quotas Integration with CloudWatch Usage Metrics."

You can use CloudWatch to proactively manage your service quotas, via CloudWatch *usage metrics*. You can use these metrics to visualize your current service usage on CloudWatch graphs and dashboards. Amazon IVS usage metrics correspond to Amazon IVS service quotas.

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. 

To access usage metrics:

1. Open the Service Quotas console at [https://console.aws.amazon.com/servicequotas/](https://console.aws.amazon.com/servicequotas/)

1. In the navigation pane, select **AWS services**.

1. From the AWS services list, search for and select **Amazon Interactive Video Service**.

1. In the **Service quotas** list, select the service quota of interest. A new page opens with information about the service quota/metric.

Alternately, you can get to these metrics through the CloudWatch console. Under **AWS Namespaces**, choose **Usage**. Then, from the **Service** list, choose **IVS**. (See [Monitoring Amazon IVS Low-Latency Streaming](stream-health.md).)

In the **AWS/Usage** namespace, Amazon IVS provides the following metric:


| Metric Name | Description | 
| --- | --- | 
| `ResourceCount` | A count of the specified resources running in your account. The resources are defined by the dimensions associated with the metric.Valid statistic: Maximum (the maximum number of resources used during the 1-minute period). | 

The following dimensions are used to refine the usage metric:


| Dimension | Description | 
| --- | --- | 
| Service | The name of the AWS service containing the resource. Valid value: `IVS`. | 
| Class | The class of resource being tracked. Valid value: `None`. | 
| Type | The type of resource being tracked. Valid value: `Resource`. | 
| Resource | The name of the AWS resource. Valid values: `ConcurrentStreams`, `ConcurrentViews`.  The ConcurrentStreams and ConcurrentViews usage metrics are copies of the ones in the **AWS/IVS** namespace (with the None dimension), as described in [Monitoring Amazon IVS Low-Latency Streaming](stream-health.md).  | 

### Creating a CloudWatch Alarm for Usage Metrics


To create a CloudWatch alarm based on an Amazon IVS usage metric: 

1. From the Service Quotas console, select the service quota of interest, as described above. Currently, alarms can be created only for ConcurrentStreams and ConcurrentViews.

1. In the **Amazon CloudWatch alarms** section, choose **Create**.

1. From the **Alarm threshold** dropdown list, choose the percentage of your applied quota value that you want to set as the alarm value.

1. For **Alarm name**, enter a name for the alarm.

1. Select **Create**.
