| _key | core | string |
| account_id | core | string |
| activity_id | core | string | The unique identifier of the scaling activity. |
| cause | core | string | A simple description of what caused the scaling activity to happen. |
| description | core | string | A simple description of what action the scaling activity intends to accomplish. |
| details | core | string | The details about the scaling activity. |
| end_time | core | timestamp | The Unix timestamp for when the scaling activity ended. |
| not_scaled_reasons | core | json | Machine-readable data that describes the reason for a not scaled activity. Only available when DescribeScalingActivities includes not scaled activities. |
| resource_id | core | string | The identifier of the resource associated with the scaling activity. This string consists of the resource type and unique identifier. - ECS service - The resource type is
service and the unique identifier is the cluster name and service name. Example: service/my-cluster/my-service. - Spot Fleet - The resource type is
spot-fleet-request and the unique identifier is the Spot Fleet request ID. Example: spot-fleet-request/sfr-73fbd2ce-aa30-494c-8788-1cee4EXAMPLE. - EMR cluster - The resource type is
instancegroup and the unique identifier is the cluster ID and instance group ID. Example: instancegroup/j-2EEZNYKUA1NTV/ig-1791Y4E1L8YI0. - AppStream 2.0 fleet - The resource type is
fleet and the unique identifier is the fleet name. Example: fleet/sample-fleet. - DynamoDB table - The resource type is
table and the unique identifier is the table name. Example: table/my-table. - DynamoDB global secondary index - The resource type is
index and the unique identifier is the index name. Example: table/my-table/index/my-table-index. - Aurora DB cluster - The resource type is
cluster and the unique identifier is the cluster name. Example: cluster:my-db-cluster. - SageMaker endpoint variant - The resource type is
variant and the unique identifier is the resource ID. Example: endpoint/my-end-point/variant/KMeansClustering. - Custom resources are not supported with a resource type. This parameter must specify the
OutputValue from the CloudFormation template stack used to access the resources. The unique identifier is defined by the service provider. More information is available in our GitHub repository. - Amazon Comprehend document classification endpoint - The resource type and unique identifier are specified using the endpoint ARN. Example:
arn:aws:comprehend:us-west-2:123456789012:document-classifier-endpoint/EXAMPLE. - Amazon Comprehend entity recognizer endpoint - The resource type and unique identifier are specified using the endpoint ARN. Example:
arn:aws:comprehend:us-west-2:123456789012:entity-recognizer-endpoint/EXAMPLE. - Lambda provisioned concurrency - The resource type is
function and the unique identifier is the function name with a function version or alias name suffix that is not $LATEST. Example: function:my-function:prod or function:my-function:1. - Amazon Keyspaces table - The resource type is
table and the unique identifier is the table name. Example: keyspace/mykeyspace/table/mytable. - Amazon MSK cluster - The resource type and unique identifier are specified using the cluster ARN. Example:
arn:aws:kafka:us-east-1:123456789012:cluster/demo-cluster-1/6357e0b2-0e6a-4b86-a0b4-70df934c2e31-5. - Amazon ElastiCache replication group - The resource type is
