NAME
Log::Log4perl::Config - Log4perl configuration file syntax
DESCRIPTION
In "Log::Log4perl", configuration files are used to describe how the system's loggers ought to behave.
The format is the same as the one as used for "log4j", just with a few perl-specific extensions, like enabling the "Bar::Twix" syntax
instead of insisting on the Java-specific "Bar.Twix".
Comment lines (starting with arbitrary whitespace and a #) and blank lines (all whitespace or empty) are ignored.
Also, blanks between syntactical entities are ignored, it doesn't matter if you write
log4perl.logger.Bar.Twix=WARN,Screen
or
log4perl.logger.Bar.Twix = WARN, Screen
"Log::Log4perl" will strip the blanks while parsing your input.
Assignments need to be on a single line. However, you can break the line if you want to by using a continuation character at the end of the
line. Instead of writing
log4perl.appender.A1.layout=Log::Log4perl::Layout::SimpleLayout
you can break the line at any point by putting a backslash at the very (!) end of the line to be continued:
log4perl.appender.A1.layout=
Log::Log4perl::Layout::SimpleLayout
Watch out for trailing blanks after the backslash, which would prevent the line from being properly concatenated.
Loggers
Loggers are addressed by category:
log4perl.logger.Bar.Twix = WARN, Screen
This sets all loggers under the "Bar::Twix" hierarchy on priority "WARN" and attaches a later-to-be-defined "Screen" appender to them.
Settings for the root appender (which doesn't have a name) can be accomplished by simply omitting the name:
log4perl.logger = FATAL, Database, Mailer
This sets the root appender's level to "FATAL" and also attaches the later-to-be-defined appenders "Database" and "Mailer" to it.
The additivity flag of a logger is set or cleared via the "additivity" keyword:
log4perl.additivity.Bar.Twix = 0|1
(Note the reversed order of keyword and logger name, resulting from the dilemma that a logger name could end in ".additivity" according to
the log4j documentation).
Appenders and Layouts
Appender names used in Log4perl configuration file lines need to be resolved later on, in order to define the appender's properties and its
layout. To specify properties of an appender, just use the "appender" keyword after the "log4perl" intro and the appender's name:
# The Bar::Twix logger and its appender
log4perl.logger.Bar.Twix = DEBUG, A1
log4perl.appender.A1=Log::Log4perl::Appender::File
log4perl.appender.A1.filename=test.log
log4perl.appender.A1.mode=append
log4perl.appender.A1.layout=Log::Log4perl::Layout::SimpleLayout
This sets a priority of "DEBUG" for loggers in the "Bar::Twix" hierarchy and assigns the "A1" appender to it, which is later on resolved to
be an appender of type "Log::Log4perl::Appender::File", simply appending to a log file. According to the "Log::Log4perl::Appender::File"
manpage, the "filename" parameter specifies the name of the log file and the "mode" parameter can be set to "append" or "write" (the former
will append to the logfile if one with the specified name already exists while the latter would clobber and overwrite it).
The order of the entries in the configuration file is not important, "Log::Log4perl" will read in the entire file first and try to make
sense of the lines after it knows the entire context.
You can very well define all loggers first and then their appenders (you could even define your appenders first and then your loggers, but
let's not go there):
log4perl.logger.Bar.Twix = DEBUG, A1
log4perl.logger.Bar.Snickers = FATAL, A2
log4perl.appender.A1=Log::Log4perl::Appender::File
log4perl.appender.A1.filename=test.log
log4perl.appender.A1.mode=append
log4perl.appender.A1.layout=Log::Log4perl::Layout::SimpleLayout
log4perl.appender.A2=Log::Log4perl::Appender::Screen
log4perl.appender.A2.stderr=0
log4perl.appender.A2.layout=Log::Log4perl::Layout::PatternLayout
log4perl.appender.A2.layout.ConversionPattern = %d %m %n
Note that you have to specify the full path to the layout class and that "ConversionPattern" is the keyword to specify the printf-style
formatting instructions.
Configuration File Cookbook
Here's some examples of often-used Log4perl configuration files:
Append to STDERR
log4perl.category.Bar.Twix = WARN, Screen
log4perl.appender.Screen = Log::Log4perl::Appender::Screen
log4perl.appender.Screen.layout =
Log::Log4perl::Layout::PatternLayout
log4perl.appender.Screen.layout.ConversionPattern = %d %m %n
Append to STDOUT
log4perl.category.Bar.Twix = WARN, Screen
log4perl.appender.Screen = Log::Log4perl::Appender::Screen
log4perl.appender.Screen.stderr = 0
log4perl.appender.Screen.layout =
Log::Log4perl::Layout::PatternLayout
log4perl.appender.Screen.layout.ConversionPattern = %d %m %n
Append to a log file
log4perl.logger.Bar.Twix = DEBUG, A1
log4perl.appender.A1=Log::Log4perl::Appender::File
log4perl.appender.A1.filename=test.log
log4perl.appender.A1.mode=append
log4perl.appender.A1.layout =
Log::Log4perl::Layout::PatternLayout
log4perl.appender.A1.layout.ConversionPattern = %d %m %n
Note that you could even leave out
log4perl.appender.A1.mode=append
and still have the logger append to the logfile by default, although the "Log::Log4perl::Appender::File" module does exactly the opposite.
This is due to some nasty trickery "Log::Log4perl" performs behind the scenes to make sure that beginner's CGI applications don't clobber
the log file every time they're called.
Write a log file from scratch
If you loathe the Log::Log4perl's append-by-default strategy, you can certainly override it:
log4perl.logger.Bar.Twix = DEBUG, A1
log4perl.appender.A1=Log::Log4perl::Appender::File
log4perl.appender.A1.filename=test.log
log4perl.appender.A1.mode=write
log4perl.appender.A1.layout=Log::Log4perl::Layout::SimpleLayout
"write" is the "mode" that has "Log::Log4perl::Appender::File" explicitely clobber the log file if it exists.
