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

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.

accept => REASONS

charset => CHARSET

Translate the text-strings into the specified charset, otherwise the sysadmin may get unreadable text.

facility => STRING

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

flags => STRING

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

format => CODE

[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.

format_reason => 'UPPERCASE'|'LOWERCASE'|'UCFIRST'|'IGNORE'|CODE

identity => STRING

include_domain => BOOLEAN

[1.00] Include the text-domain of the message in each logged message.

locale => LOCALE

logsocket => 'unix'|'inet'|'stream'|HASH

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().
