You can check whether the prediction based on a predictive scaling rule meets your expectations so that you can determine whether to make corresponding adjustments. For example, if the predictive mode of a predictive scaling rule is set to Predict Only and the prediction meets your expectations, you can set the predictive mode to Predict and Scale. This way, Auto Scaling can automatically adjust the minimum and maximum numbers of instances.
- Log on to the Auto Scaling console.
- In the left-side navigation pane, click Scaling Groups.
- In the top navigation bar, select the region where Auto Scaling is activated.
- Find a scaling group and use one of the following methods to go to the scaling group details page:
- Click the ID of the scaling group in the Scaling Group Name/ID column.
- Click Details in the Actions column.
- In the upper part of the page that appears, click the Scaling Rules and Event-triggered Tasks tab.
- On the Scaling Rules tab, find the predictive scaling rule and click its ID in the Scaling Rule ID/Name column. You can set the predictive mode to Predict and Scale after you confirm that the prediction meets your expectations. For more information, see Modify a scaling rule.You can go to the details page of the scaling rule to view multiple metrics that can help you evaluate the effect of the prediction.
