* By default messages are formatted as:

|
*
|
|
* To override the log format (e.g. to add your own info) define the format key when configuring
|
|
* this logger
|

*
|
|
* If you wish to include a prefix to all messages, for instance to identify the

|
* the prefix is shared by all streams using syslog, as it is dependent of
|
|
* the running process. For a local prefix, to be used only by one stream, you
|
|
* can use the format key.
|
|
*
|
|
* ## Example:
|
|
*
|
|
* {{{
|
|
* CakeLog::config('error', array(
|
|
* 'engine' => 'Syslog',
|
|
* 'types' => array('emergency', 'alert', 'critical', 'error'),
