--
-- Gets information about the instance refreshes for the specified Auto
-- Scaling group.
--
-- This operation is part of the
-- <https://docs.aws.amazon.com/autoscaling/ec2/userguide/asg-instance-refresh.html instance refresh feature>
-- in Amazon EC2 Auto Scaling, which helps you update instances in your
-- Auto Scaling group after you make configuration changes.
--
-- To help you determine the status of an instance refresh, this operation
-- returns information about the instance refreshes you previously
-- initiated, including their status, end time, the percentage of the
-- instance refresh that is complete, and the number of instances remaining
-- to update before the instance refresh is complete.
--
-- The following are the possible statuses:
--
-- -   @Pending@ - The request was created, but the operation has not
--     started.
--
-- -   @InProgress@ - The operation is in progress.
--
-- -   @Successful@ - The operation completed successfully.
--
-- -   @Failed@ - The operation failed to complete. You can troubleshoot
--     using the status reason and the scaling activities.
--
-- -   @Cancelling@ - An ongoing operation is being cancelled. Cancellation
--     does not roll back any replacements that have already been
--     completed, but it prevents new replacements from being started.
--
-- -   @Cancelled@ - The operation is cancelled.
