[log4perl-devel] multiple log levels at root

[Craig <cr...@po...>]

Hi.

I have an app where I want to log the following:
	stdout: ERROR
	stderr: ERROR
	file: INFO
Also, I need to be able to change the level for stdout during run-time.

I have a simple test script with the following config:

$conf = {
'log4perl.logger' => "ERROR, Screen, OutError, File",

'log4perl.filter.Info' => 'Log::Log4perl::Filter::LevelRange',
'log4perl.filter.Info.LevelMin' => 'INFO',
'log4perl.filter.Info.LevelMax' => 'FATAL',
'log4perl.filter.Info.AcceptOnMatch' => 'true',

'log4perl.filter.Warn' => 'Log::Log4perl::Filter::LevelRange',
'log4perl.filter.Warn.LevelMin' => 'WARN',
'log4perl.filter.Warn.LevelMax' => 'FATAL',
'log4perl.filter.Warn.AcceptOnMatch' => 'true',

"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" => 'ok: %p>%M-%L: %m%n',

"log4perl.appender.OutError" => "Log::Log4perl::Appender::Screen",
"log4perl.appender.OutError.Filter" => 'Warn',
"log4perl.appender.OutError.stderr"  => "1",
"log4perl.appender.OutError.layout" => 
"Log::Log4perl::Layout::PatternLayout",
"log4perl.appender.OutError.layout.ConversionPattern" => 'ok: %p>%M-%L: 
%m%n',

"log4perl.appender.File" => "Log::Log4perl::Appender::File",
"log4perl.appender.File.Filter" => 'Info',
"log4perl.appender.File.mode" => 'append',
"log4perl.appender.File.filename" => "app-multi.log",
"log4perl.appender.File.layout" => "Log::Log4perl::Layout::PatternLayout",
"log4perl.appender.File.layout.ConversionPattern" => '%p>%M-%L: %m%n'
};
Log::Log4perl::init($conf);
$logger = get_logger($name);

Problem is that I need to *always* send info (and "up") messages to the 
file and error (and "up") to stderr regardless of what the root logger 
level is set to. But, I also need to be able to change the stdout level 
on the fly. I don't want to set the default root level to anything less 
than ERROR, which means that only error and up will then be sent to the 
file.

(Basically, I have a "verbose" switch on the app where I turn down the 
level for stdout. But, the default should be pretty non-chatty.)

Does this all make sense? (Not sure if I explained it very well.)

Any ideas would be appreciated!

Thanx
Craig
