  ## tidb cluster to be monitored
  ## ** now only support monitoring one tidb cluster **
  clusters:
  - name: advanced-tidb
    namespace: default
    ## ClusterDomain is the domain of TidbCluster object
    # clusterDomain: cluster.local

  ## ConfigUpdateStrategy determines how the configuration change is applied to the cluster.
  ## Valid values are `InPlace` and `RollingUpdate`
  ##   UpdateStrategy `InPlace` will update the ConfigMap of configuration in-place and an extra rolling update of the
  ##   cluster component is needed to reload the configuration change.
  ##   UpdateStrategy `RollingUpdate` will create a new ConfigMap with the new configuration and rolling update the
  ##   related components to use the new ConfigMap, that is, the new configuration will be applied automatically.
  configUpdateStrategy: RollingUpdate

  ## Persistent volume reclaim policy applied to the PV consumed, default to `Retain`.
  ## Note that the reclaim policy Recycle may not be supported by some storage types, e.g. local.

  pvReclaimPolicy: Retain

  ## ImagePullPolicy of Pods
  ## Ref: https://kubernetes.io/docs/concepts/configuration/overview/#container-images
  # imagePullPolicy: IfNotPresent

  ## If private registry is used, imagePullSecrets may be set
  ## You can also set this in service account
  ## Ref: https://kubernetes.io/docs/concepts/containers/images/#specifying-imagepullsecrets-on-a-pod
  # imagePullSecrets:
  # - name: secretName

  ## Specify pod priorities of pods in TidbNGMonitoring, default to empty.
  ## Can be overwritten by component settings.
  ## Ref: https://kubernetes.io/docs/concepts/configuration/pod-priority-preemption/
  # priorityClassName: system-cluster-critical

  ## Use the node network namespace, default to false
  ## Ref: https://kubernetes.io/docs/concepts/policy/pod-security-policy/#host-namespaces
  # hostNetwork: false

  ## if true, this ng monitoring cluster is paused and will not be synced by the controller
  # paused: false

  ## SchedulerName of pods.
  ## If specified, the pods will be scheduled by the specified scheduler.
  ## Can be overwritten by component settings.
  # schedulerName: default-scheduler
