-Alert output for use with Barnyard2 (unified2.alert)
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-.. note:: Unified2 output has been deprecated and will be removed by
-          December 2019. Please see the `deprecation policy`_ for more
-          information.
-
-This log format is a binary format compatible with the unified2 output
-of another popular IDS format and is designed for use with Barnyard2
-or other tools that consume the unified2 log format.
-
-By default a file with the given filename and a timestamp (unix epoch
-format) will be created until the file hits the configured size limit,
-then a new file, with a new timestamp will be created. It is the job
-of other tools, such as Barnyard2 to cleanup old unified2 files.
-
-If the `nostamp` option is set the log file will not have a timestamp
-appended. The file will be re-opened on SIGHUP like other log files
-allowing external log rotation tools to work as expected. However, if
-the limit is reach the file will be deleted and re-opened.
-
-This output supports IPv6 and IPv4 events.
