Table name (macros) are not the issue, here is how I’m currently creating a table:

destination mysql {

sql(type(mysql)

host("localhost") username("syslog") password("xxx")

database("syslog")

table("syslog_${R_YEAR}${R_MONTH}${R_DAY}")

columns("id int(11) unsigned not null auto_increment primary key", "host varchar(40) not null", "facility varchar(20)", "priority varchar(10)", "level varchar(10)", "program text", "date date not null", "time time not null", "message text not null")

values("", "$FULLHOST", "$FACILITY", "$PRIORITY", "$LEVEL", "$PROGRAM", "$R_YEAR-$R_MONTH-$R_DAY", "$R_HOUR:$R_MIN:$R_SEC", "$MSG")

indexes("id","host","priority"));

};

This creates a table like this:

syslog_20170306 | CREATE TABLE `syslog_20170306` (

  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,

  `host` varchar(40) NOT NULL,

  `facility` varchar(20) DEFAULT NULL,

  `priority` varchar(10) DEFAULT NULL,

  `level` varchar(10) DEFAULT NULL,

  `program` text,

  `date` date NOT NULL,

  `time` time NOT NULL,

  `message` text NOT NULL,

  PRIMARY KEY (`id`),

  KEY `syslog_20170306_id_idx` (`id`),

  KEY `syslog_20170306_host_idx` (`host`),

  KEY `syslog_20170306_priority_idx` (`priority`)

) ENGINE=MyISAM AUTO_INCREMENT=10485923 DEFAULT CHARSET=latin1

That is the output from my old syslog server, the new will be using InnoDB tables, not MyISAM, as listed.  If you notice the last parameters, starting with “ENGINE” - that is where the additional parameters can be added.  in a compressed table you would append a ROW_FORMAT variable.  Here is a little information if you’re curious:

Hi,

syslog-ng can automatically create tables if you use macros in the table names.

As for additional options, newer syslog-ng versions have a dbd-option() that can be used to set database options when syslog-ng connects the database (it might or might not be enough for your needs), see https://www.balabit.com/documents/syslog-ng-ose-latest-guides/en/syslog-ng-ose-guide-admin/html/reference-destination-sql.html

HTH,

Robert
