Log::Report::Dispatcher::Syslog(3) User Contributed Perl Documentation 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 Extends "DESCRIPTION" in Log::Report::Dispatcher. METHODS Extends "METHODS" in Log::Report::Dispatcher. Constructors Extends "Constructors" in Log::Report::Dispatcher. $class->new($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. Improves base, see "Constructors" in Log::Report::Dispatcher -Option --Defined in --Default accept Log::Report::Dispatcher depend on mode charset 'utf8' facility 'user' flags 'pid,nowait' format format_reason Log::Report::Dispatcher 'IGNORE' identity > include_domain false locale Log::Report::Dispatcher logsocket undef mode Log::Report::Dispatcher 'NORMAL' to_prio [] accept => $reasons|\@reasons charset => $charset Translate the text-strings into the specified $charset, otherwise the sysadmin may get unreadable text. facility => $facility The possible values for this depend (a little) on the system. POSIX only defines "user", and "local0" up to "local7". flags => $flags Any combination of $flags as defined by Sys::Syslog, as comma-separated string. Examples for flags are: "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 => $program 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 => \@PAIRS See reasonToPrio().
