Instead, you may use the [metrics server](https://github.com/kubernetes-incubator/metrics-server). It's a simplified heapster that is able to gather and serve current metrics values. It provides the Metrics API that is used by `kubectl top`, and horizontal pod autoscaler. Note that it doesn't include some features of Heapster, such as short term metrics for graphs in kube-dashboard and dedicated push sinks, which proved hard to maintain and scale. Clusters using Heapster for transferring metrics into...

evicts pods from nodes in preparation for disruptive operations like kernel
upgrades or maintenance.
     * Custom Metrics for Autoscaling (HorizontalPodAutoscaler API in the Autoscaling
API group): The Horizontal Pod Autoscaling feature now supports custom metrics
(Alpha), allowing you to specify application-level metrics and thresholds to
trigger scaling up and down the number of pods in your application.

 *  Fix: Gracefully recover from HTTP/2 connection shutdowns at start of request.
 *  Fix: Be lenient if a `MediaType`'s character set is `'single-quoted'`.
 *  Fix: Allow horizontal tab characters in header values.
 *  Fix: When parsing HTTP authentication headers permit challenge parameters in any order.


## Version 3.4.2

_2016-11-03_

*   HPA tolerance is now configurable by setting the `horizontal-pod-autoscaler-tolerance` flag. ([#52275](https://github.com/kubernetes/kubernetes/pull/52275),[ @mattjmcnaughton](https://github.com/mattjmcnaughton))

### SIG-autoscaling

SIG Autoscaling focused on improving the Horizontal Pod Autoscaling API and algorithm:
- We released autoscaling/v2beta2, which cleans up and unifies the API
- We improved readiness detection and smoothing to work well in a larger variety or use cases

### SIG-Azure

- If we set SelectPolicy MinPolicySelect on scaleUp behavior or scaleDown behavior,Horizontal Pod Autoscaler doesn't automatically scale the number of pods correctly ([#95647](https://github.com/kubernetes/kubernetes/pull/95647), [@JoshuaAndrew](https://github.com/JoshuaAndrew)) [SIG Apps and Autoscaling]
