In the control panel or with CLI tool, users can define autoscaling conditions based on CPU load thresholds and minimum duration to tailor actions to their workload demands:
1721
- **CPU Load Threshold:** Specifies the CPU load percentage that triggers autoscaling using a range slider.
1822
- **Minimum Duration:** Determines the minimum duration, in minutes, for the CPU load to exceed the threshold to activate autoscaling.

## Autoscaling Triggering Process

- **Continuous Monitoring:** The autoscaling agent continually monitors your application's CPU load.

- **Activation Conditions:** Autoscaling is triggered if the CPU load surpasses the defined threshold and duration criteria set by the user.

- **Activation Conditions:** Autoscaling is triggered if the CPU load surpasses the defined threshold and duration criteria set by the user or default values that were set when the feature was enabled.

## Autoscaling Workflow

- **Initial Cooldown period:** A 5-minute cooldown period after enabling autoscaling prevents rapid scaling due to sudden spikes.

- **A fallback duration of 15 minutes**: Ensures a minimum interval for reassessment when the user-defined duration is less than 15 minutes.

This approach selects the longer duration between user-defined settings or the fallback duration before initiating the next autoscaling event. It ensures adequate time for evaluating resource changes on CPU performance.

To halt continued autoscaling behavior, simply turn off the autoscaling feature in your control panel. This prevents subsequent autoscaling triggers after the initial action.

**Important to know:**

- For the next 24 hours, plan adjustments are restricted. If necessary, please contact support for assistance.
45+
- If there are still insufficient resources and the conditions are met, the system will initiate another autoscaling process with a cooldown period of 5 minutes.
46+
- It will scale up to the largest plan available within the same provider.
47+
- Downscaling takes place within 24 hours from the initial autoscaling event.
