NAME ^

Log::Report::Dispatcher::Syslog - send messages to syslog

INHERITANCE ^

 Log::Report::Dispatcher::Syslog
   is a Log::Report::Dispatcher

SYNOPSIS ^

 # add syslog dispatcher
 dispatcher SYSLOG => 'syslog', accept => 'NOTICE-'
   , format_reason => 'IGNORE'
   , to_prio => [ 'ALERT-' => 'err' ];

 # disable default dispatcher, when daemon
 dispatcher close => 'default';

DESCRIPTION ^

This dispatchers produces output to syslog, based on the Sys::Syslog module (which will NOT be automatically installed for you, because some systems have a problem with this dependency).

The REASON for a message often uses names which are quite similar to the log-levels used by syslog. However: they have a different purpose. The REASON is used by the programmer to indicate the cause of the message: whether it was able to handle a certain situation. The syslog levels are there for the user's of the program (with syslog usually the system administrators). It is not unusual to see a "normal" error or mistake as a very serious situation in a production environment. So, you may wish to translate any message above reason MISTAKE into a LOG_CRIT.

The default translation table is list below. You can change the mapping using new(to_prio). See example in SYNOPSIS.

  TRACE   => LOG_DEBUG    ERROR   => LOG_ERR
  ASSERT  => LOG_DEBUG    FAULT   => LOG_ERR
  INFO    => LOG_INFO     ALERT   => LOG_ALERT
  NOTICE  => LOG_NOTICE   FAILURE => LOG_EMERG
  WARNING => LOG_WARNING  PANIC   => LOG_CRIT
  MISTAKE => LOG_WARNING

METHODS ^

Constructors

$obj->close()

See "Constructors" in Log::Report::Dispatcher

Log::Report::Dispatcher::Syslog->new(TYPE, NAME, OPTIONS)

With syslog, people tend not to include the REASON of the message in the logs, because that is already used to determine the destination of the message.

 -Option       --Defined in             --Default
  accept         Log::Report::Dispatcher  depend on mode
  charset        Log::Report::Dispatcher  <undef>
  facility                                'user'

  logsocket                               undef

  to_prio                                 []
accept => REASONS
charset => CHARSET
facility => STRING

The possible values for this depend (a little) on the system. POSIX only defines 'user' and 'local0' upto 'local7'.

flags => STRING

Any combination of flags as defined by Sys::Syslog, for instance pid, ndelay, and nowait.

format_reason => 'UPPERCASE'|'LOWERCASE'|'UCFIRST'|'IGNORE'|CODE
identity => STRING
locale => LOCALE
logsocket => 'unix'|'inet'|'stream'

If specified, the log socket type will be initialized to this before openlog is called. If not specified, the system default is used.

mode => 'NORMAL'|'VERBOSE'|'ASSERT'|'DEBUG'|0..3
to_prio => ARRAY-of-PAIRS

See reasonToPrio().
