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

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


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

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

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.

Translate the text-strings into the specified charset, otherwise the sysadmin may get unreadable text.
The possible values for this depend (a little) on the system. POSIX only defines "user", and "local0" up to "local7".
Any combination of flags as defined by Sys::Syslog, for instance "pid", "ndelay", and "nowait".
[1.10] With a CODE reference you get your hands on the text before it gets sent to syslog. The three parameters are: the (translated) text, the related text domain object, and the message object. You may want to use context information from the latter.

[1.19] After the three positional parameters, there may be a list of pairs (named parameters) with additional info. This may contain a "location" with an ARRAY of information produced by caller() about the origin of the exception.

[1.00] Include the text-domain of the message in each logged message.
If specified, the log socket type will be initialized to this before "openlog()" is called. If not specified, the system default is used.
