| [pause\_time](#input\_pause\_time) | Time to wait for a new instance to check-in before marking it as failed. Specify PauseTime in the ISO8601 duration format (in the format PT#H#M#S, where each # is the number of hours, minutes, and seconds, respectively). | `string` | `"PT5M"` | no |
| [scaling\_object\_type](#input\_scaling\_object\_type) | The object type the autoscaling group should use as the basis for its instances. The default value is 'LaunchTemplate'.
