| monitor_dimension       | core | string     | For customer managed monitors, do not specify this field. For Amazon Web Services managed monitors, this field controls which cost dimension is automatically analyzed by the monitor. For <code>TAG</code> and <code>COST_CATEGORY </code> dimensions, you must also specify MonitorSpecification to configure the specific tag or cost category key to analyze.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         |

| monitor_type            | core | string     | The type of the monitor. Set this to <code>DIMENSIONAL</code> for an Amazon Web Services managed monitor. Amazon Web Services managed monitors automatically track up to the top 5,000 values by cost within a dimension of your choosing. Each dimension value is evaluated independently. If you start incurring cost in a new value of your chosen dimension, it will automatically be analyzed by an Amazon Web Services managed monitor. Set this to <code>CUSTOM</code> for a customer managed monitor. Customer managed monitors let you select specific dimension values that get monitored in aggregate.
