Administrators may set logging levels for several Hybrid Data Pipeline services using the hdplogging.properties file, as described in Configuring logging. Supported settings vary depending on the service. See the following sections for details.

Note: The location of data source logs is determined by the hdpLoggingDir property in the update.properties file. However, data source logging levels are configured separately. For information on configuring data source logging levels, refer to Data source logging in the Hybrid Data Pipeline User's Guide.
