EventBridge Scheduler 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 about service quotas, see Quotas for Amazon EventBridge Scheduler.

These metrics are contained in the AWS/Usage namespace, rather than AWS/Scheduler, and are collected every minute. CloudWatch publishes metrics in this namespace with the dimensions Service, Class, Type, and Resource.

Common dimensions for usage metrics
Dimension Description

Service

The name of the AWS service containing the resource. For EventBridge Scheduler usage metrics, the value is Scheduler.

Class

The class of resource being tracked. For EventBridge Scheduler usage metrics, the value is None.

Type

The type of resource being tracked. For API usage metrics, the value is API. For resource count metrics, the value is Resource.

Resource

The specific resource being tracked. For API usage metrics, this is the API operation name. For resource count metrics, this is the resource type being counted.

API usage metrics

API usage metrics track the number of API operations performed in your account. Use these metrics to monitor API call volume and manage your API rate quotas.

The metric name is CallCount. The most useful statistic for this metric is SUM, which represents the total operation count for the 1-minute period.

API usage metrics
Metric Resource Description

CallCount

CreateSchedule

The number of CreateSchedule API operations performed in your account.

CallCount

CreateScheduleGroup

The number of CreateScheduleGroup API operations performed in your account.

CallCount

DeleteSchedule

The number of DeleteSchedule API operations performed in your account.

CallCount

DeleteScheduleGroup

The number of DeleteScheduleGroup API operations performed in your account.

CallCount

GetSchedule

The number of GetSchedule API operations performed in your account.

CallCount

GetScheduleGroup

The number of GetScheduleGroup API operations performed in your account.

CallCount

ListScheduleGroups

The number of ListScheduleGroups API operations performed in your account.

CallCount

ListSchedules

The number of ListSchedules API operations performed in your account.

CallCount

ListTagsForResource

The number of ListTagsForResource API operations performed in your account.

CallCount

TagResource

The number of TagResource API operations performed in your account.

CallCount

UntagResource

The number of UntagResource API operations performed in your account.

CallCount

UpdateSchedule

The number of UpdateSchedule API operations performed in your account.

For example, the CallCount metric with the following dimensions indicates the number of times the CreateSchedule API operation has been called in your account:

  • "Service": "Scheduler"

  • "Class": "None"

  • "Type": "API"

  • "Resource": "CreateSchedule"

Resource count metrics

Resource count metrics track the approximate number of resources in your account. Use these metrics to monitor when you are approaching your service quota limits, allowing you to request quota increases before running out of capacity.

The metric name is ResourceCount. The most useful statistic for this metric is Maximum.

Resource count metrics
Metric Resource Description

ResourceCount

ApproximateSchedule

Approximate number of schedules in your account. Use this metric to monitor when you are approaching your schedules quota limit, to help you avoid ServiceQuotaExceededException errors when calling CreateSchedule.

When the number of schedules is less than 1 million, this metric may show zero. For an alarm to notify when nearing your schedules quota, we recommend using the Maximum statistic with a threshold of 5 million or higher, since the default schedules quota is 10 million.

ResourceCount

ApproximateScheduleGroup

Approximate number of schedule groups in your account. Use this metric to monitor when you are approaching your schedule groups quota limit, to help you avoid ServiceQuotaExceededException errors when calling CreateScheduleGroup.

For example, the ResourceCount metric with the following dimensions and the Maximum statistic indicates the approximate number of schedules in your account:

  • "Service": "Scheduler"

  • "Class": "None"

  • "Type": "Resource"

  • "Resource": "ApproximateSchedule"
