Enables group metrics collection for the specified Auto Scaling group.

You can use these metrics to track changes in an Auto Scaling group and to set alarms on threshold values.

You can specify one or more of the following metrics:

  • GroupMinSize
  • GroupMaxSize
  • GroupDesiredCapacity
  • GroupInServiceInstances
  • GroupPendingInstances
  • GroupStandbyInstances
  • GroupTerminatingInstances
  • GroupTotalInstances
  • GroupInServiceCapacity
  • GroupPendingCapacity
  • GroupStandbyCapacity
  • GroupTerminatingCapacity
  • GroupTotalCapacity
  • WarmPoolDesiredCapacity
  • WarmPoolWarmedCapacity
  • WarmPoolPendingCapacity

(string)

Syntax:

"string" "string" ...

--granularity (string)

The frequency at which Amazon EC2 Auto Scaling sends aggregated data to CloudWatch. The only valid value is 1Minute .

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

Example 1: To enable metrics collection for an Auto Scaling group

This example enables data collection for the specified Auto Scaling group.

aws autoscaling enable-metrics-collection \
    --auto-scaling-group-name my-asg \
    --granularity "1Minute"

This command produces no output.

For more information, see Monitoring CloudWatch metrics for your Auto Scaling groups and instances in the Amazon EC2 Auto Scaling User Guide.

Example 2: To collect data for the scpecified metric for an Auto Scaling group

To collect data for a specific metric, use the --metrics option.

aws autoscaling enable-metrics-collection \
    --auto-scaling-group-name my-asg \
    --metrics GroupDesiredCapacity --granularity "1Minute"

This command produces no output.
