1 telemetry.api.php hook_telemetry_data($telemetry_key)

Populates the telemetry data from this module.

Data collected in this hook should be entirely anonymous. Returning data such as IP Addresses, personal information, the site name, or other values is not allowed. Contributed modules that return such information may be subject to removal from the Backdrop Contributed module repository.

string $telemetry_key: Unique identifier of the data to be collected.

Return value

string: The value for the requested data.
