Parse syslog messages into separate MySQL tables with rsyslog

Question

Out of the box rsyslog will dump everything into the SystemEvents table within the `Syslog database (if you use the default schema provided). I would like to use a regular expression to filter inbound messages into separate database tables.

I've played with this, but I'm having a hard time figuring out the best way to accomplish this (or even a way that functions).

In my rsyslog.conf:

$template wireless, \
 "insert into RogueAPs \
 (ReceivedAt, DeviceReportedTime, Facility, Priority, FromHost, Message) \
 VALUES('%timegenerated%', '%timereported%', '%syslogfacility%', '%syslogpriority%', '%fromhost-ip%', '%msg%');", \ 
 stdsql

if $msg contains 'subtype=wireless' then :ommysql:127.0.0.1,Syslog,dbusername,dbpassword;wireless

*.* :ommysql:127.0.0.1,Syslog,dbusername,dbpassword

This was my latest attempt, but I'm stuck.

(the RogueAPs table is just a clone of the default SystemEvents table that ships with rsyslog)

Solution

from taking a look at this tutorial, I see no difference.

But taking a look at the template documentation from rsyslog, there seems to be a difference with mysql depending on the setting for parameter NO_BACKSLASH_ESCAPES.

From the docs:

sql - format the string suitable for a SQL statement in MySQL format. This will 
replace single quotes ("'") and the backslash character by their backslash-escaped
counterpart ("\'" and "\\") inside each field. Please note that in MySQL
configuration, the NO_BACKSLASH_ESCAPES mode must be turned off for this format to
work (this is the default).

stdsql - format the string suitable for a SQL statement that is to be sent to a
standards-compliant sql server. This will replace single quotes ("'") by two single
quotes ("''") inside each field. You must use stdsql together with MySQL if in MySQL
configuration the NO_BACKSLASH_ESCAPES is turned on.
