MySQL Database Output Module

Module Name:    ommysql

Author: Michael Meckelein (Initial Author) / Rainer Gerhards <rgerhards@adiscon.com>

Description:

This module provides native support for logging to MySQL databases. It offers superior performance over the more generic omlibdbi module.

Configuration Directives:

ommysql mostly uses the "old style" configuration, with almost everything on the action line itself. A few newer features are being migrated to the new style-config directive configuration system.

• $ActionOmmysqlServerPort <port>
  Permits to select a non-standard port for the MySQL server. The default is 0, which means the system default port is used. There is no need to specify this directive unless you know the server is running on a non-standard listen port.
• Action parameters:
  :ommysql:database-server,database-name,database-userid,database-password
  All parameters should be filled in for a successful connect.

Note rsyslog contains a canned default template to write to the 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 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.

Sample:

The following sample writes all syslog messages to the database "syslog_db" on mysqlsever.example.com. The server is being accessed under the account of "user" with password "pwd".
