.. data:: module_wait_module
Module is waiting for another module.
.. data:: module_wait_subquery
Module is waiting for sub-query.
.. data:: module_error
Module could not finish the query.
.. data:: module_finished
Module is finished with query.
Module event
~~~~~~~~~~~~~
.. data:: module_event_new
New DNS query.
.. data:: module_event_pass

.. data:: module_event_reply

Security status
~~~~~~~~~~~~~~~~
.. data:: sec_status_unchecked
Means that object has yet to be validated.
.. data:: sec_status_bogus
Means that the object *(RRset or message)* failed to validate
*(according to local policy)*, but should have validated.
.. data:: sec_status_indeterminate
Means that the object is insecure, but not
authoritatively so. Generally this means that the RRset is not
below a configured trust anchor.
.. data:: sec_status_insecure
Means that the object is authoritatively known to be
insecure. Generally this means that this RRset is below a trust
anchor, but also below a verified, insecure delegation.
.. data:: sec_status_secure
Means that the object (RRset or message) validated according to local policy.
