 title: Sending Apollo Router usage data to Apollo Studio
 ---
 
-The Apollo Router can transmit usage data to Apollo Studio via a reporting agent called **Spaceport**. By default, Spaceport runs automatically as a component _within_ the Apollo Router. Additional details on its modes of operation are provided below.

-## Advanced configuration (not recommended)

-Spaceport can run either as an internal component of a single Apollo Router instance, or as an external resource shared by _multiple_ router instances.
-
-For the majority of users, an internal Spaceport instance is sufficient.

-To connect the Apollo Router to an external Spaceport instance, specify its endpoint URL in your YAML config file:

-## Running Spaceport externally (not recommended)

-Running spaceport as a separate process currently requires building from [source](https://github.com/apollographql/router/tree/main/apollo-spaceport).
