NAME

6       Log::Report::Dispatcher::Syslog - send messages to syslog
7

INHERITANCE

9        Log::Report::Dispatcher::Syslog
10          is a Log::Report::Dispatcher
11

SYNOPSIS

13        # add syslog dispatcher
14        dispatcher SYSLOG => 'syslog', accept => 'NOTICE-'
15          , format_reason => 'IGNORE'
16          , to_prio => [ 'ALERT-' => 'err' ];
17
18        # disable default dispatcher, when daemon
19        dispatcher close => 'default';
20

DESCRIPTION

22       This dispatchers produces output to syslog, based on the Sys::Syslog
23       module (which will NOT be automatically installed for you, because some
24       systems have a problem with this dependency).
25
26       The REASON for a message often uses names which are quite similar to
27       the log-levels used by syslog.  However: they have a different purpose.
28       The REASON is used by the programmer to indicate the cause of the
29       message: whether it was able to handle a certain situation.  The syslog
30       levels are there for the user's of the program (with syslog usually the
31       system administrators).  It is not unusual to see a "normal" error or
32       mistake as a very serious situation in a production environment. So,
33       you may wish to translate any message above reason MISTAKE into a
34       LOG_CRIT.
35
36       The default translation table is list below.  You can change the
37       mapping using new(to_prio).  See example in SYNOPSIS.

57       Log::Report::Dispatcher::Syslog->new($type, $name, %options)
58           With syslog, people tend not to include the REASON of the message
59           in the logs, because that is already used to determine the
60           destination of the message.

75
76           accept => REASONS
77           charset => CHARSET
78             Translate the text-strings into the specified charset, otherwise
79             the sysadmin may get unreadable text.
80
81           facility => STRING
82             The possible values for this depend (a little) on the system.
83             POSIX only defines "user", and "local0" up to "local7".
84
85           flags => STRING
86             Any combination of flags as defined by Sys::Syslog, for instance
87             "pid", "ndelay", and "nowait".
88
89           format => CODE
90             [1.10] With a CODE reference you get your hands on the text
91             before it gets sent to syslog.  The three parameters are: the
92             (translated) text, the related text domain object, and the
93             message object.  You may want to use context information from the
94             latter.
95
96             [1.19] After the three positional parameters, there may be a list
97             of pairs (named parameters) with additional info.  This may
98             contain a "location" with an ARRAY of information produced by
99             caller() about the origin of the exception.
100
101           format_reason => 'UPPERCASE'|'LOWERCASE'|'UCFIRST'|'IGNORE'|CODE
102           identity => STRING
103           include_domain => BOOLEAN
104             [1.00] Include the text-domain of the message in each logged
105             message.
106
107           locale => LOCALE
108           logsocket => 'unix'|'inet'|'stream'|HASH
109             If specified, the log socket type will be initialized to this
110             before "openlog()" is called.  If not specified, the system
111             default is used.
112
113           mode => 'NORMAL'|'VERBOSE'|'ASSERT'|'DEBUG'|0..3
114           to_prio => ARRAY-of-PAIRS
115             See reasonToPrio().
