  - `maximum` - (Required) The maximum number of instances for this resource. Valid values are between 0 and 1000.
  - `minimum` - (Required) The minimum number of instances for this resource. Valid values are between 0 and 1000.

    - `metric_resource_id` - (Optional) The ID of the Resource which the Rule monitors.
    - `operator` - (Required) Specifies the operator used to compare the metric data and threshold. Possible values are: Equals, NotEquals, GreaterThan, GreaterThanOrEqual, LessThan, LessThanOrEqual.
    - `statistic` - (Required) Specifies how the metrics from multiple instances are combined. Possible values are Average, Max, Min and Sum.

    - `time_grain` - (Required) Specifies the granularity of metrics that the rule monitors, which must be one of the pre-defined values returned from the metric definitions for the metric. This value must be between 1 minute and 12 hours an be formatted as an ISO 8601 string.
    - `time_window` - (Required) Specifies the time range for which data is collected, which must be greater than the delay in metric collection (which varies from resource to resource). This value must be between 5 minutes and 12 hours and be formatted as an ISO 8601 string.
    - `threshold` - (Required) Specifies the threshold of the metric that triggers the scale action.
    - `metric_namespace` - (Optional) The namespace of the metric that defines what the rule monitors, such as microsoft.compute/virtualmachinescalesets for Virtual Machine Scale Sets.
    - `dimensions` - (Optional) One or more dimensions block as defined below.
      - `name` - (Required) The name of the dimension.
      - `operator` - (Required) The dimension operator. Possible values are Equals and NotEquals. Equals means being equal to any of the values. NotEquals means being not equal to any of the values.
      - `values` - (Required) A list of dimension values.
    - `divide_by_instance_count` - (Optional) Whether to enable metric divide by instance count.
  - `scale_action` - (Required) A scale_action block as defined below.
    - `cooldown` - (Required) The amount of time to wait since the last scaling action before this action occurs. Must be between 1 minute and 1 week and formatted as a ISO 8601 string.
    - `direction` - (Required) The scale direction. Possible values are Increase and Decrease.
    - `type` - (Required) The type of action that should occur. Possible values are ChangeCount, ExactCount, PercentChangeCount and ServiceAllowedNextValue.

  - `end` - (Required) Specifies the end date for the profile, formatted as an RFC3339 date string.
  - `start` - (Required) Specifies the start date for the profile, formatted as an RFC3339 date string.
  - `timezone` - (Optional) The Time Zone of the start and end times. Defaults to UTC.
- `recurrence` - (Optional) A recurrence block as defined below. This cannot be specified if a fixed_date block is specified.
