4.2. Common configuration options

You can adjust the CPU, memory, or storage resource requests and/or limits for pods and volumes. The default-resource-limits.yaml below provides an example of setting resource request and limits for each component.

apiVersion: metering.openshift.io/v1
kind: MeteringConfig
metadata:
  name: "operator-metering"
spec:
  reporting-operator:
    spec:
      resources:
        limits:
          cpu: 1
          memory: 500Mi
        requests:
          cpu: 500m
          memory: 100Mi
  presto:
    spec:
      coordinator:
        resources:
          limits:
            cpu: 4
            memory: 4Gi
          requests:
            cpu: 2
            memory: 2Gi

      worker:
        replicas: 0
        resources:
          limits:
            cpu: 8
            memory: 8Gi
          requests:
            cpu: 4
            memory: 2Gi

  hive:
    spec:
      metastore:
        resources:
          limits:
            cpu: 4
            memory: 2Gi
          requests:
            cpu: 500m
            memory: 650Mi
        storage:
          class: null
          create: true
          size: 5Gi
      server:
        resources:
          limits:
            cpu: 1
            memory: 1Gi
          requests:
            cpu: 500m
            memory: 500Mi

You can run the metering components on specific sets of nodes. Set the nodeSelector on a metering component to control where the component is scheduled. The node-selectors.yaml file below provides an example of setting node selectors for each component.

apiVersion: metering.openshift.io/v1
kind: MeteringConfig
metadata:
  name: "operator-metering"
spec:
  reporting-operator:
    spec:
      nodeSelector:
        "node-role.kubernetes.io/infra": "" 1

  presto:
    spec:
      coordinator:
        nodeSelector:
          "node-role.kubernetes.io/infra": "" 2
      worker:
        nodeSelector:
          "node-role.kubernetes.io/infra": "" 3
  hive:
    spec:
      metastore:
        nodeSelector:
          "node-role.kubernetes.io/infra": "" 4
      server:
        nodeSelector:
          "node-role.kubernetes.io/infra": "" 5
