The following ``describe-instance-refreshes`` example returns a description of all instance refresh requests for the specified Auto Scaling group, including the status message and (if available) the status reason. ::

    aws autoscaling describe-instance-refreshes \
        --auto-scaling-group-name my-asg 

Output::
