Horizontal Pod Scaling Tolerance

It specifies the minimum change (from 1.0) in the desired-to-actual metrics ratio for the HPA to consider scaling.

The configuration determines how quickly the HPA will act to auto scaling policies. If the parameter is set to 0, auto scaling will be triggered immediately when the related metrics are met.

Value Range

Greater than or equal to 0

Default Value

0.1

Modifiable

Yes

Suggestions

Configure this parameter based on actual needs. If the service resource usage increases sharply over time, retain a certain tolerance to prevent auto scaling which is beyond expectation in high resource usage scenarios.
