# Log::Report::Dispatcher::Syslog(3pm)

send messages to syslog

## 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

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                                   <unchanged>
    format_reason   Log::Report::Dispatcher  'IGNORE'
    identity                                 <basename C<$0>>
    include_domain                           false
    locale          Log::Report::Dispatcher  <system locale>
    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()**.

### Attributes

Extends "Attributes" in Log::Report::Dispatcher.

- $obj-\>**format**( \[CODE\] )

  Returns the `"CODE"` ref which formats the syslog line.

- $obj-\>**isDisabled**()

  Inherited, see "Attributes" in Log::Report::Dispatcher

- $obj-\>**mode**()

  Inherited, see "Attributes" in Log::Report::Dispatcher

- $obj-\>**name**()

  Inherited, see "Attributes" in Log::Report::Dispatcher

- $obj-\>**needs**( \[$reason\] )

  Inherited, see "Attributes" in Log::Report::Dispatcher

- $obj-\>**type**()

  Inherited, see "Attributes" in Log::Report::Dispatcher

### Logging

Extends "Logging" in Log::Report::Dispatcher.

- $any-\>**addSkipStack**(@CODE)

  Inherited, see "Logging" in Log::Report::Dispatcher

- $obj-\>**close**()

  Inherited, see "Logging" in Log::Report::Dispatcher

- $any-\>**collectLocation**()

  Inherited, see "Logging" in Log::Report::Dispatcher

- $any-\>**collectStack**( \[$maxdepth\] )

  Inherited, see "Logging" in Log::Report::Dispatcher

- $obj-\>**log**(\\%options, $reason, $message, $domain)

  Inherited, see "Logging" in Log::Report::Dispatcher

- $obj-\>**reasonToPrio**($reason)

  Returns a level which is understood by [**syslog**(3)](/syslog/3.md), based on a translation table.  This can be changed with new(to\_prio).

- $obj-\>**skipStack**()

  Inherited, see "Logging" in Log::Report::Dispatcher

- $any-\>**stackTraceLine**(%options)

  Inherited, see "Logging" in Log::Report::Dispatcher

- $obj-\>**translate**(\\%options, $reason, $message)

  Inherited, see "Logging" in Log::Report::Dispatcher
