Prometheus Metrics

Prometheus metrics exported by Kueue

Kueue exposes prometheus metrics to monitor the health of the system and the status of ClusterQueues.

Kueue health

Use the following metrics to monitor the health of the kueue controllers:

Metric name Type Description Labels
kueue_admission_attempts_total Counter The total number of attempts to admit workloads. Each admission attempt might try to admit more than one workload. result: possible values are success or inadmissible
kueue_admission_attempt_duration_seconds Histogram The latency of an admission attempt. result: possible values are success or inadmissible

ClusterQueue status

Use the following metrics to monitor the status of your ClusterQueues:

Metric name Type Description Labels
kueue_pending_workloads Gauge The number of pending workloads. cluster_queue: the name of the ClusterQueue
status: possible values are active or inadmissible
kueue_quota_reserved_workloads_total Counter The total number of quota reserved workloads. cluster_queue: the name of the ClusterQueue
kueue_quota_reserved_wait_time_seconds Histogram The time between a workload was created or requeued until it got quota reservation. cluster_queue: the name of the ClusterQueue
kueue_admitted_workloads_total Counter The total number of admitted workloads. cluster_queue: the name of the ClusterQueue
kueue_evicted_workloads_total Counter The total number of evicted workloads. cluster_queue: the name of the ClusterQueue
reason: Possible values are Preempted, PodsReadyTimeout, AdmissionCheck, ClusterQueueStopped or InactiveWorkload
kueue_admission_wait_time_seconds Histogram The time between a workload was created or requeued until admission. cluster_queue: the name of the ClusterQueue
kueue_admission_checks_wait_time_seconds Histogram The time from when a workload got the quota reservation until admission. cluster_queue: the name of the ClusterQueue
kueue_admitted_active_workloads Gauge The number of admitted Workloads that are active (unsuspended and not finished) cluster_queue: the name of the ClusterQueue
kueue_cluster_queue_status Gauge Reports the status of the ClusterQueue cluster_queue: The name of the ClusterQueue
status: Possible values are pending, active or terminated. For a ClusterQueue, the metric only reports a value of 1 for one of the statuses.

Optional metrics

The following metrics are available only if metrics.enableClusterQueueResources is enabled in the manager’s configuration.

Metric name Type Description Labels
kueue_cluster_queue_resource_usage Gauge Reports the ClusterQueue’s total resource usage cohort: The cohort in which the queue belongs
cluster_queue: The name of the ClusterQueue
flavor: referenced flavor
resource: The resource name
kueue_cluster_queue_nominal_quota Gauge Reports the ClusterQueue’s resource quota cohort: The cohort in which the queue belongs
cluster_queue: The name of the ClusterQueue
flavor: referenced flavor
resource: The resource name
kueue_cluster_queue_borrowing_limit Gauge Reports the ClusterQueue’s resource borrowing limit cohort: The cohort in which the queue belongs
cluster_queue: The name of the ClusterQueue
flavor: referenced flavor
resource: The resource name
kueue_cluster_queue_weighted_share Gauge Reports a value that representing the maximum of the ratios of usage above nominal quota to the lendable resources in the cohort, among all the resources provided by the ClusterQueue. cluster_queue: The name of the ClusterQueue
