parameters:
  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: json

  RoleName:
    default: ''
    description: Role name on which the service is applied

  RoleParameters:
    default: {}
    description: Parameters specific to the role
    type: json

    default: []
    description: List of scheduler available filters
    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.
  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.
