Metrics

Karpenter writes several metrics to Prometheus to allow monitoring cluster provisioning status

Provisioner Metrics

karpenter_provisioner_limit

The Provisioner Limits are the limits specified on the provisioner that restrict the quantity of resources provisioned. Labeled by provisioner name and resource type.

karpenter_provisioner_usage

The Provisioner Usage is the amount of resources that have been provisioned by a particular provisioner. Labeled by provisioner name and resource type.

karpenter_provisioner_usage_pct

The Provisioner Usage Percentage is the percentage of each resource used based on the resources provisioned and the limits that have been configured in the range [0,100]. Labeled by provisioner name and resource type.

Nodes Metrics

karpenter_nodes_allocatable

Node allocatable are the resources allocatable by nodes. Labeled by provisioner name, node name, zone, architecture, capacity type, instance type, node phase and resource type.

karpenter_nodes_system_overhead

Node system daemon overhead are the resources reserved for system overhead, the difference between the node’s capacity and allocatable values are reported by the status. Labeled by provisioner name, node name, zone, architecture, capacity type, instance type, node phase and resource type.

karpenter_nodes_total_daemon_limits

Node total pod limits are the resources specified by DaemonSet pod limits. Labeled by provisioner name, node name, zone, architecture, capacity type, instance type, node phase and resource type.

karpenter_nodes_total_daemon_requests

Node total daemon requests are the resource requested by DaemonSet pods bound to nodes. Labeled by provisioner name, node name, zone, architecture, capacity type, instance type, node phase and resource type.

karpenter_nodes_total_pod_limits

Node total pod limits are the resources specified by non-DaemonSet pod limits. Labeled by provisioner name, node name, zone, architecture, capacity type, instance type, node phase and resource type.

karpenter_nodes_total_pod_requests

Node total pod requests are the resources requested by non-DaemonSet pods bound to nodes. Labeled by provisioner name, node name, zone, architecture, capacity type, instance type, node phase and resource type.

Pods Metrics

karpenter_pods_state

Pod state is the current state of pods. This metric can be used several ways as it is labeled by the pod name, namespace, owner, node, provisioner name, zone, architecture, capacity type, instance type and pod phase.

Cloudprovider Metrics

karpenter_cloudprovider_duration_seconds

Duration of cloud provider method calls. Labeled by the controller, method name and provider.

Allocation_controller Metrics

karpenter_allocation_controller_scheduling_duration_seconds

Duration of scheduling process in seconds. Broken down by provisioner and error.
