- Add one metrics(`kubelet_volume_stats_health_abnormal`) of volume health state to kubelet ([#105585](https://github.com/kubernetes/kubernetes/pull/105585), [@fengzixu](https://github.com/fengzixu))

- In the kubelet resource metrics endpoint at /metrics/resource, change the names of the following metrics:
  - node_cpu_usage_seconds --> node_cpu_usage_seconds_total

  - Applications that fetch metrics from kube-scheduler should use a dedicated service account which is allowed to access nonResourceURLs `/metrics`. ([#96345](https://github.com/kubernetes/kubernetes/pull/96345), [@ingvagabund](https://github.com/ingvagabund)) [SIG Cloud Provider, Scheduling and Testing]

- Metric `running_managed_controllers` is enabled for Cloud Node Lifecycle controller. ([#111033](https://github.com/kubernetes/kubernetes/pull/111033), [@jprzychodzen](https://github.com/jprzychodzen))

# Metrics Version 3

In metrics version 3, all metrics are available under the endpoint:

```
/minio/metrics/v3
```

however, a specific path under this is required.

Metrics are organized into groups at paths **relative** to the top-level endpoint above.

## Metrics Request Handling

Each endpoint below can be queried at different intervals as needed via a scrape configuration in Prometheus or a compatible metrics collection tool.

    TFE_MonitoringCounterCell* cell);

// APIs for Counter without label.
typedef struct TFE_MonitoringCounter0 TFE_MonitoringCounter0;
// Returns a new Counter metric object. The caller should manage lifetime of
// the object. Using duplicate metric name will crash the program with fatal
// error.
TF_CAPI_EXPORT extern TFE_MonitoringCounter0* TFE_MonitoringNewCounter0(
    const char* name, TF_Status* status, const char* description);
