ommysql: MariaDB/MySQL Database Output Module

Server

This is the address of the MariaDB/MySQL-Server.

Socket

This is the unix socket path of the MariaDB/MySQL-Server. When the server address is set localhost, the MariaDB/MySQL client library connects using the default unix socket specified at build time. If you run MariaDB/MySQL server and run the unix socket path differently than the default, you can set the socket path with this option.

db

This is the name of the database used.

UID

This is the user who is used.

PWD

This is the password for the user specified in UID.

ServerPort

Permits to select a non-standard port for the MariaDB/MySQL server. The default is 0, which means the system default port is used. There is no need to specify this parameter unless you know the server is running on a non-standard listen port.

MySQLConfig.File

Permits the selection of an optional MariaDB/MySQL Client Library configuration file (my.cnf) for extended configuration functionality. The use of this configuration parameter is necessary only if you have a non-standard environment or if fine-grained control over the database connection is desired.

MySQLConfig.Section

Permits the selection of the section within the configuration file specified by the $OmMySQLConfigFile parameter. This will likely only be used where the database administrator provides a single configuration file with multiple profiles. This configuration parameter is ignored unless $OmMySQLConfigFile is also used in the rsyslog configuration file. If omitted, the MariaDB/MySQL Client Library default of “client” will be used.

Template

Rsyslog contains a canned default template to write to the MariaDB/MySQL database. It works on the MonitorWare schema. This template is:

$template tpl,"insert into SystemEvents (Message, Facility, FromHost,
Priority, DeviceReportedTime, ReceivedAt, InfoUnitID, SysLogTag) values
('%msg%', %syslogfacility%, '%HOSTNAME%', %syslogpriority%,
'%timereported:::date-mysql%', '%timegenerated:::date-mysql%', %iut%,
'%syslogtag%')",SQL

As you can see, the template is an actual SQL statement. Note the “,SQL” option: it tells the template processor that the template is used for SQL processing, thus quote characters are quoted to prevent security issues. You can not assign a template without “,SQL” to a MariaDB/MySQL output action.

If you would like to change fields contents or add or delete your own fields, you can simply do so by modifying the schema (if required) and creating your own custom template.
