The Feast project has a feature to log usage statistics and errors. Several client methods are tracked, beginning in Feast 0.9. Users are assigned a UUID which is sent along with the name of the method, the Feast version, the OS (using sys.platform), and the current time.

The source code is available here.

Set the environment variable FEAST_USAGE to True (in String type) and config your endpoint by the variable FEAST_USAGE_ENDPOINT.
