Metrics

The metric configuration defines which metric type is watched by the Autoscaler.

Configuring scale bounds

You can configure upper and lower bounds to control autoscaling behavior.

You can also specify the initial scale that a Revision is scaled to immediately after creation. This can be a default configuration for all Revisions, or for a specific Revision using an annotation.

Targets

Configuring a target provide the Autoscaler with a value that it tries to maintain for the configured metric for a revision. See the metrics - https://knative.dev/docs/serving/autoscaling/autoscaling-metrics/ documentation for more information about configurable metric types.

Configuring the requests per second (RPS) target

This setting specifies a target for requests-per-second per replica of an application.

Supported Autoscaler types

Knative Serving supports the implementation of Knative Pod Autoscaler (KPA) and Kubernetes’ Horizontal Pod Autoscaler (HPA). This topic lists the features and limitations of each of these Autoscalers, as well as how to configure them.
