Auto Scaling：ModifyEciScalingConfiguration

A required parameter. Set the value to ModifyEciScalingConfiguration.

The ID of the scaling configuration to modify.

The name of the scaling configuration. The name must be 2 to 64 characters in length. It can contain letters, digits, Chinese characters, underscores (_), hyphens (-), and periods (.). The name must start with a letter, a digit, or a Chinese character.
