[log4perl-devel] Configuration question

[Albert V. <av...@im...>]

Hi

    I've got a configuration problem. We have a main logger.conf 
containing the main configuration options, with their appenders, 
layouts, etc. However, sometimes, we need a custom logger appender in 
addition to the main configuration.
    How can I initialize the log4perl with the main logger.conf and add 
a new custom appenders?

    The init method erases any previous initialization. Is there an 
init_append like method?


Thanks

Hi,

probably a simple question, but I cannot figure it out:

I have configured a logger for category "Test" to log all DEBUG messages - but for one child-category "Test.child1" I only want the INFO messages.

What I tried is:
---
log4j.logger.Test=DEBUG, MyFileAppender
log4j.logger.Test.Child1=INFO, MyFileAppender

log4j.additivity.Test=true
log4j.additivity.Test.Child1=false
---
but this didn't work ....

How to achieve my goal?

Johannes

Looks good to me:

    use Log::Log4perl qw(:easy);
    Log::Log4perl->init(\ q{
     log4j.logger.Test=DEBUG, Screen
     log4j.logger.Test.Child1=INFO, Screen

     log4j.additivity.Test=true
     log4j.additivity.Test.Child1=false
     log4j.appender.Screen = Log::Log4perl::Appender::Screen
     log4j.appender.Screen.layout = SimpleLayout
    });

    get_logger("Test")->debug("test debug log");
    get_logger("Test")->info("test info log");

    get_logger("Test::Child1")->debug("child1 debug log");
    get_logger("Test::Child1")->info("child1 info log");

yields

    DEBUG - test debug log
    INFO - test info log
    INFO - child1 info log

Isn't that what you'd expect?

We've thought about this issue a while ago, but got away from it
because of implications like users accidently overwriting previous
settings. Nobody stops you from dynamically assembling your conf file,
though, so you could still "add" configuration lines before calling
"init".

It would be helpful to know what the purpose of the additional
appender is -- it's possible that you could use a custom filter
instead.
