Metering

meshStack supports metering and billing for most common OpenShift versions.

Prerequisites​

  • The "meshfed-metering" service account must be configured as described here
  • CPU and memory limits have to be defined for all containers, as metering is currently based on these limits
  • OpenShift APIs are accessible by meshStack metering collector components

Supported Resources​

Resources with the following traits are addressable in the Product Catalog. Platform engineers can use the traits of these resources to define fine-granular product and pricing rules.

Currently OpenShift metering is based on Pods. They are metered via the configured limit of CPU and memory of their containers.

Pod​

let PodResourceTraits =
    {-
      milliCpu:
        Configured total CPU limit of all containers in this Pod, in milli CPU (1/1000 of a CPU).
        The primitive usage quantity unit in product catalog entries is 'mCPU', e.g. '2500 mCPU'.

      ramMb:
        Configured total RAM limit of all containers in this Pod, in MiB.
        The primitive usage quantity unit in product catalog entries is 'MiBy', e.g. '1024 MiBy'.

      status:
        Status phase of this pod. See https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle/
    -}
      { milliCpu : Integer, ramMb : Integer, status : Text }
let example
    : PodResourceTraits
    = { milliCpu = +2500, ramMb = +1024, status = "Running" }

PersistentVolumeClaim​

let PersistentVolumeClaimResourceTraits =
    {-
      status:
        Status phase of this PersistentVolumeClaim. See https://docs.openshift.com/container-platform/4.1/storage/understanding-persistent-storage.html#pv-phase_understanding-persistent-storage

      storageClassName:
        Name of the Storage Class used for this volume.

      storageMb:
        Total Capacity of the Volume, in MiB.
    -}
      { status : Text, storageClassName : Text, storageMb : Integer }
let example
    : PersistentVolumeClaimResourceTraits
    = { status = "Bound", storageClassName = "slow", storageMb = +5120 }
