To gather emissions data pertaining to your data centers, it is necessary to give a unique name to your entities and associate a location in such a way that they can retrieve data from all of your data center locations. For instance, if you wish to utilize the metric definition named Energy from coal, it implies that you want the coal energy emissions data from four locations, for example, Bangalore, New York, Paris, and Berlin when the metrics are executed. To accomplish this task, you need to create entities with names such as New York, Bangalore, and so on. To use the Sustainable IT application, when you create entities, it is mandatory to add a location to them. You can then group the entities within an entity type. For example, you can call the entity type "Data centers." This entity type is then added to the metric definition named Energy from coal.
