To disable metrics collection for an Auto Scaling group

This example disables collection of the GroupDesiredCapacity metric for the specified Auto Scaling group.

aws autoscaling disable-metrics-collection \
    --auto-scaling-group-name my-asg \
    --metrics GroupDesiredCapacity

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 1: This example disables monitoring of the specified metrics for the specified Auto Scaling group.

Disable-ASMetricsCollection -AutoScalingGroupName my-asg -Metric @("GroupMinSize", "GroupMaxSize")

Example 2: This example disables monitoring of all metrics for the specified Auto Scaling group.
