Log::Handler::Levels(3pm) | User Contributed Perl Documentation | Log::Handler::Levels(3pm) |
NAME¶
Log::Handler::Levels - All levels for Log::Handler.
DESCRIPTION¶
Base class for Log::Handler.
Just for internal usage and documentation.
METHODS¶
Default log level¶
Checking for active levels¶
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".
