# GroupPolicyScaleInAction

Defines the action to be taken when the 'scaleInThreshold' is exceeded. Here, scaling is always about removing VMs associated with this VM Auto Scaling Group. By default, the termination policy is 'OLDEST\_SERVER\_FIRST' is effective.

The value must be between 1 to 10. 'amountType=PERCENTAGE' specifies the percentage value that is applied to the current number of replicas of the VM Auto Scaling Group. The value must be between 1 to 200. At least one VM is always added or removed. Note that for 'SCALE\_IN' operations, volumes are not deleted after the server is deleted.                                                     |                                |

With a scaling action in progress, no second scaling action is started for the same VM Auto Scaling Group. Instead, the metric is re-evaluated after the current scaling action completes (either successfully or with errors). This is currently validated with a minimum value of 2 minutes and a maximum value of 24 hours. The default value is 5 minutes if not specified. | \[optional] \[default to '5m'] |

When set to \`false\`, all volumes remain in the datacenter and must be deleted manually. **Note**, that every scale-out creates new volumes. When they are not deleted, they will eventually use all of your contracts resource limits. At this point, scaling out would not be possible anymore.                                                                                     |                                |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ionos.com/cloud/python/vm-autoscaling/models/grouppolicyscaleinaction.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
