'Returns a page of :class:`Alert` resources as a list.
For paging information see :class:`ListResource`.
**NOTE**: Due to the potentially voluminous amount of data in an
alert, the full HTTP request and response data is only returned
in the Alert instance resource representation.
:param date after: Only list alerts logged after this datetime
:param date before: Only list alerts logger before this datetime
:param log_level: If \'error\', only shows errors. If \'warning\',
only show warnings'
