- A new kubelet metric `image_pull_duration_seconds` was added. The metric tracks the duration (in seconds) it takes for an image to be pulled, including the time spent in the waiting queue of image puller. The metric is broken down by bucketed image size.

- Component owner can configure the allowlist of metric label with flag '--allow-metric-labels'. ([#99385](https://github.com/kubernetes/kubernetes/pull/99385), [@YoyinZyc](https://github.com/YoyinZyc)) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation and Release]

- Introduced new apiserver metric `apiserver_flowcontrol_current_inqueue_seats`. This metric is analogous to `apiserver_flowcontrol_current_inqueue_requests`, but tracks the total number of seats, as each request can take more than one seat. ([#119385](https://github.com/kubernetes/kubernetes/pull/119385), [@andrewsykim](https://github.com/andrewsykim))

- Change  `preemption_victims` metric bucket from `LinearBuckets` to `ExponentialBuckets`. ([#112939](https://github.com/kubernetes/kubernetes/pull/112939), [@lengrongfu](https://github.com/lengrongfu)) [SIG Instrumentation and Scheduling]
- Extend the job `job_finished_total metric by new `reason` label and introduce a new job metric to count pod failures

- Scheduler now waits for handlers to finish syncing before the scheduling cycles start. ([#116729](https://github.com/kubernetes/kubernetes/pull/116729), [@AxeZhan](https://github.com/AxeZhan))

- HPA controller exposes the following metrics from the kube-controller-manager. 
  - `metric_computation_duration_seconds`: The time(seconds) that the HPA controller takes to calculate one metric.
  - `metric_computation_total`: Number of metric computations. ([#116326](https://github.com/kubernetes/kubernetes/pull/116326), [@sanposhiho](https://github.com/sanposhiho)) [SIG Apps, Autoscaling and Instrumentation]

- Introduction of a new "sync_proxy_rules_no_local_endpoints_total" proxy metric. This metric represents the number of services with no internal endpoints. The "traffic_policy" label will contain both "internal" or "external". ([#108930](https://github.com/kubernetes/kubernetes/pull/108930), [@MaxRenaud](https://github.com/MaxRenaud))...

- Added `apiserver_longrunning_requests` metric to replace the soon to be deprecated `apiserver_longrunning_gauge` metric. ([#103799](https://github.com/kubernetes/kubernetes/pull/103799), [@jyz0309](https://github.com/jyz0309))
- Controller-manager: the following flags have no effect and would be removed in v1.24:
