Following the metrics which are exported and provided by controller-runtime by default:
|Current depth of workqueue.
|Total number of adds handled by workqueue.
|How long in seconds an item stays in workqueue before being requested.
|How long in seconds processing an item from workqueue takes.
|How many seconds of work has been done that is in progress and hasn’t been observed by work_duration. Large values indicate stuck threads. One can deduce the number of stuck threads by observing the rate at which this increases.
|How many seconds has the longest running processor for workqueue been running.
|Total number of retries handled by workqueue.
|Number of HTTP requests, partitioned by status code, method, and host.
|Total number of reconciliations per controller.
|Total number of reconciliation errors per controller.
|Total number of terminal errors from the reconciler.
|Length of time per reconciliation per controller.
|Maximum number of concurrent reconciles per controller.
|Number of currently used workers per controller.
|Histogram of the latency of processing admission requests.
|Total number of admission requests by HTTP status code.
|Current number of admission requests being served.
