More a man page than a real +# sample ;) +# +# We try to keep things as consistent with existing syslog implementation +# as possible. We use "$" to start lines that contain new directives. +# Set syslogd options + +# Templates are a key feature of rsyslog. They allow to specify any +# format a user might want. Every output in rsyslog uses templates - this +# holds true for files, user messages and so on. The database writer +# expects its template to be a proper SQL statement - so this is highly +# customizable too. You might ask how does all of this work when no templates +# at all are specified. Good question ;) The answer is simple, though. Templates +# compatible with the stock syslogd formats are hardcoded into rsyslog. So if +# no template is specified, we use one of these hardcoded templates. Search for +# "template_" in syslogd.c and you will find the hardcoded ones. +# +# A template consists of a template directive, a name, the actual template text +# and optional options. A sample is: +# +# $template MyTemplateName,"\7Text %property% some more text\n", +# +# The "$template" is the template directive. It tells rsyslog that this +# line contains a template. +# +# "MyTemplateName" is the template name. All other config lines refer to +# this name. +# +# The text within quotes is the actual template text. The backslash is +# a escape character, much as in C. It does all these "cool" things. For +# example, \7 rings the bell (this is an ASCII value), \n is a new line. +# C programmers and perl coders have the advantage of knowing this, but the +# set in rsyslog is a bit restricted currently. All text in the template +# is used literally, except for things within percent signs. These are +# properties and allow you access to the contents of the syslog message. +# Properties are accessed via the property replacer (nice name, huh) and +# it can do cool things, too. For example, it can pick a substring or +# do date-specific formatting. More on this is below, on some lines of the +# property replacer. +# +# The part is optional. It carries options that influence the +# template as whole. Details are below. Be sure NOT to mistake template +# options with property options - the later ones are processed by the +# property replacer and apply to a SINGLE property, only (and not the +# whole template). +# +# Template options are case-insensitive. Currently defined are: +# sql - format the string suitable for a SQL statement. This will replace single +# quotes ("'") by two single quotes ("''") inside each field. This option MUST +# be specified when a template is used for writing to a database, otherwise SQL +# injection might occur. +# +# Please note that the database writer *checks* that the sql option is +# present in the template. If it is not present, the write database action +# is disabled. This is to guard you against accidential forgetting it and +# then becoming vulnerable for SQL injection. +# The sql option can also be useful with files - especially if you want +# to run them on another machine for performance reasons. However, do NOT +# use it if you do not have a real need for it - among others, it takes +# some toll on the processing time. Not much, but on a really busy system +# you might notice it ;) +# +# To escape: +# % = \% +# \ = \\ +# --> '\' is used to escape (as in C) +#$template TraditionalFormat,%timegenerated% %HOSTNAME% %syslogtag%%msg%\n" +# +# Properties can be accessed by the property replacer.

They specify the +# offset within the string that should be copied. Offset counting +# starts at 1, so if you need to obtain the first 2 characters of the +# message text, you can use this syntax: "%msg:1:2%". +# If you do not whish to specify from and to, but you want to +# specify options, you still need to include the colons.
