The Kubernetes scheduler is a control plane process that assigns Pods to the nodes. The scheduler determines which nodes are valid placements for each Pod in the scheduling queue according to the constraints and available resources. The scheduler then ranks each valid node and binds the Pod to a suitable node. Multiple different schedulers may be used within a cluster. By default, the kube-scheduler runs on port 10251 and exposes the metrics of /metrics in openMetric format. The Agent hits the endpoint with the kubernetes client and fetches the metrics automatically. Therefore, no extra configuration or detection logic is required.


Go to Resources under the Infrastructure tab to check if your resources are onboarded and the metrics are collected.
