When using Cost Explorer, you can filter your costs by this service dimension to see charges related to your Direct Connect connections. These charges typically include port hours for dedicated or hosted connections and data transfer out (DTO) costs.

If you're using the Cost Explorer API rather than the GUI, you would use the SERVICE dimension type with DirectConnect as the value when creating your filters.

Remember that Direct Connect costs consist of three main components:

1. Port hour charges (for the time your connection is provisioned)
2. Data transfer out (DTO) charges (for data sent out of AWS through your Direct Connect location)
3. SiteLink charges (if you're using that feature)

You can further break down these costs using additional dimensions like usage type to see more granular details about your Direct Connect spending.
