  ServiceData:
    default: {}
    description: Dictionary packing service data
    type: json
  ServiceNetMap:
    default: {}
    description: Mapping of service_name -> network name. Typically set
                 via parameter_defaults in the resource registry.  This
                 mapping overrides those in ServiceNetMapDefaults.

    type: comma_delimited_list
  NovaSchedulerDefaultFilters:
    type: comma_delimited_list
    default: []
    description: >
      An array of filters used by Nova to filter a node.These filters will be
      applied in the order they are listed, so place your most restrictive
      filters first to make the filtering process more efficient.
  NovaSchedulerMaxAttempts:
    type: number
    default: 3
    description: >
     Maximum number of attempts the scheduler will make when deploying the
     instance. You should keep it greater or equal to the number of bare
     metal nodes you expect to deploy at once to work around potential race
     conditions when scheduling.
  MonitoringSubscriptionNovaScheduler:
    default: 'overcloud-nova-scheduler'
    type: string
  NovaSchedulerLoggingSource:
    type: json
    default:
      tag: openstack.nova.scheduler
      path: /var/log/nova/nova-scheduler.log
  NovaSchedulerDiscoverHostsInCellsInterval:
    type: number
    default: -1
    description: >
      This value controls how often (in seconds) the scheduler should
      attempt to discover new hosts that have been added to cells.
      The default value of -1 disables the periodic task completely.
      It is recommended to set this parameter for deployments using Ironic.
