Following the metrics which are exported and provided by controller-runtime by default:
| Metrics name | Type | Description |
|---|---|---|
| workqueue_depth | Gauge | Current depth of workqueue. |
| workqueue_adds_total | Counter | Total number of adds handled by workqueue. |
| workqueue_queue_duration_seconds | Histogram | How long in seconds an item stays in workqueue before being requested. |
| workqueue_work_duration_seconds | Histogram | How long in seconds processing an item from workqueue takes. |
| workqueue_unfinished_work_seconds | Gauge | 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. |
| workqueue_longest_running_processor_seconds | Gauge | How many seconds has the longest running processor for workqueue been running. |
| workqueue_retries_total | Counter | Total number of retries handled by workqueue. |
| rest_client_requests_total | Counter | Number of HTTP requests, partitioned by status code, method, and host. |
| controller_runtime_reconcile_total | Counter | Total number of reconciliations per controller. |
| controller_runtime_reconcile_errors_total | Counter | Total number of reconciliation errors per controller. |
| controller_runtime_terminal_reconcile_errors_total | Counter | Total number of terminal errors from the reconciler. |
| controller_runtime_reconcile_time_seconds | Histogram | Length of time per reconciliation per controller. |
| controller_runtime_max_concurrent_reconciles | Gauge | Maximum number of concurrent reconciles per controller. |
| controller_runtime_active_workers | Gauge | Number of currently used workers per controller. |
| controller_runtime_webhook_latency_seconds | Histogram | Histogram of the latency of processing admission requests. |
| controller_runtime_webhook_requests_total | Counter | Total number of admission requests by HTTP status code. |
| controller_runtime_webhook_requests_in_flight | Gauge | Current number of admission requests being served. |
