| **unit**        | [**Array<SLOHistoryMetricsSeriesMetadataUnit>**](SLOHistoryMetricsSeriesMetadataUnit.md) | An array of metric units that contains up to two unit objects. For example, bytes represents one unit object and bytes per second represents two unit objects. If a metric query only has one unit object, the second array element is null. | [optional] |

## Example

```ruby
require 'datadog_api_client/v1'

instance = DatadogAPIClient::V1::SLOHistoryMetricsSeriesMetadata.new(
  aggr: null,
  expression: null,
  metric: null,
  query_index: null,
  scope: null,
  unit: [{"family":"bytes","id":2,"name":"byte","plural":"bytes","scale_factor":1.0,"short_name":"B"},null]
)
