man Log::Handler::Levels (3): All levels for Log::Handler.

DESCRIPTION

Base class for Log::Handler.

Just for internal usage and documentation.

METHODS

Default log level

debug()
info()
notice()
warning(), warn()
error(), err()
critical(), crit()
alert()
emergency(), emerg()

Checking for active levels

is_debug()
is_info()
is_notice()
is_warning(), is_warn()
is_error(), is_err()
is_critical(), is_crit()
is_alert()
is_emergency(), is_emerg()

Special level

fatal(): Alternative for the levels "critical" - "emergency".
is_fatal(): Check if one of the levels "critical" - "emergency" is active.

Special methods

trace()

This method is very useful if you want to add a full backtrace to your message. Maybe you want to intercept unexpected errors and want to know who called "die()".

    $SIG{__DIE__} = sub { $log->trace(emergency => @_) };

By default the backtrace is logged as level "debug".

    # would log with the level debug
    $log->trace('who called who');

If you want to log with another level then you can pass the level as first argument:

    $log->trace(info => $message);

dump()

If you want to dump something then you can use "dump()". The default level is "debug".

    my %hash = (foo => 1, bar => 2);
    $log->dump(\%hash);

If you want to log with another level then you can pass the level as first argument:

    $log->dump($level => \%hash);

die()

This method logs the message to the output and then call "Carp::croak()" with the level "emergency" by default.

    $log->die('an emergency error here');

If you want to log with another level, then you can pass the level as first argument:

    $log->die(fatal => 'an emergency error here');

log()

With this method it's possible to log messages with the log level as first argument:

    $log->log(info => 'an info message');

Is the same like

    $log->info('an info message');

and

    $log->log('an info message');

If you log without a level then the default level is "info".
