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

Dhall Type

Example

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

Dhall Type

Example

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 }
