.. _audit_provider: Query Auditing -------------- GeoMesa provides a Java SPI to audit queries. Auditing can be enabled when creating a ``DataStore`` by setting the parameter ``geomesa.query.audit`` to ``true`` in the connection map. Audits are written to log files under the logger name ``org.locationtech.geomesa.utils.audit.AuditLogger$``. In Accumulo, audits are also written to the ``_queries`` table. As GeoMesa can run in many environments, determining **who** executed a query is delegated to a service class. Services need to implement ``org.locationtech.geomesa.utils.audit.AuditProvider``. Third-party implementations can be enabled by placing them on the classpath and including a special service descriptor file. See the `Oracle Javadoc `__ for details on implementing a service provider. The GeoMesa GeoServer plugins come bundled with an ``AuditProvider`` that pulls user credentials from GeoServer's Spring security framework - ``org.locationtech.geomesa.security.SpringAuditProvider``.
