Metrics (v1.32)
This page details the metrics that different Kubernetes components export. You can query the metrics endpoint for these
components using an HTTP scrape, and fetch the current metrics data in Prometheus format.

reconstruct_volume_operations_errors_total
The number of volumes that failed reconstruction from the operating system during kubelet startup.

replicaset_controller_sorting_deletion_age_ratio
The ratio of chosen deleted pod's ages to the current youngest pod's age (at the time). Should be <2. The intent of this metric is to measure the rough efficacy of the LogarithmicScaleDown feature gate's effect on the sorting (and deletion) of pods when a replicaset scales down. This only considers Ready pods when calculating and reporting.
