NAME

Lib::Log4cplus - Perl interface to log via Log4cplus

VERSION

Version 0.001

SYNOPSIS

  use Lib::Log4cplus;

  my $logger = Lib::Log4cplus->new(config_file => "/path/to/config.properties");
  $logger->log_info("main", "Lib::Log4cplus works great!");

DESCRIPTION

INTERFACE

Lib::Log4cplus has some low-level XS functions (which are not exported) and a few methods suitable for class.

FUNCTIONS

All these functions are provided by the XS API to log4cplus. Nothing is exported by default and it's not recommended to use any of the functions directly.

basic_configure

  basic_configure(logToStdErr);

Enables a builtin basic configuration:

  rootLogger=DEBUG, STDOUT
  appender.STDOUT=log4cplus::ConsoleAppender
  appender.STDOUT.logToStdErr=0

Any currently existing configuration is not reset.

The parameter logToStdErr is ignored at the moment and will passed at a later release of log4cplus.

See http://log4cplus.sourceforge.net/docs/html/classlog4cplus_1_1BasicConfigurator.html for more details.

file_configure

  file_configure("/path/to/logger.properties");

Enables a configuration which is stored in a file.

Any currently existing configuration is not reset.

See http://log4cplus.sourceforge.net/docs/html/classlog4cplus_1_1PropertyConfigurator.html for more details.

static_configure

  my $properties = <<EOP;
  rootLogger=DEBUG, STDOUT
  appender.STDOUT=log4cplus::ConsoleAppender
  appender.STDOUT.logToStdErr=0
  EOP

  static_configure($properties);

Enables a configuration which is given by a list of properties separated by newlines.

Any currently existing configuration is not reset.

See http://log4cplus.sourceforge.net/docs/html/classlog4cplus_1_1PropertyConfigurator.html for more details.

log4cplus_add_log_level

  log4cplus_add_log_level(INFO_LOG_LEVEL+1, "BASIC")

Introduces a new log level which can be used to express severities a bit clearer. Returns false when the new loglevel or name already exists, respectively.

log4cplus_remove_log_level

  log4cplus_remove_log_level(INFO_LOG_LEVEL+1, "BASIC")

Removes a previously added log level (where log4cplus_add_log_level returned true). Returns false when either loglevel or name can't be resolved to each other.

logger_exists

  say "Yes" if logger_exists("wuff");
  say "Always" if logger_exists(undef);

Tells whether the specified logger exists. The rootLogger does always exists, even if it might not be configured.

logger_is_enabled_for

  say "Noisy" if logger_is_enabled_for(undef, 10000); # DEBUG_LOG_LEVEL
  say "Oops" unless logger_is_enabled_for("security", 30000); # WARN_LOG_LEVEL

Tells whether the specified logger will log the requested log-level. The log-level has to be specified as an integer constant as described in the API documentation of log4cplus. The constant routine allows to fetch a bunch of log-level values predefined during configuration process.

See http://log4cplus.sourceforge.net/docs/html/clogger_8h.html for more details.

logger_log

  logger_log("access", 20000, $resource->path . " 200 OK") == 0 or die "Logger broken";

Takes a message (one string - not more, not formats) and pass it to the assigned appenders, if log-level is turned on for the logger.

logger_force_log

  logger_force_log("access", 20000, $resource->path . " 200 OK") == 0 or die "Logger broken";

Takes a message (one string - not more, not formats) and pass it to the assigned appenders, regardless whether log-level is turned on for the logger or not.
