 * By default messages are formatted as:
30
 *         type: message
31
 *
32
 * To override the log format (e.g. to add your own info) define the format key when configuring
33
 * this logger
34
 *
35
 * If you wish to include a prefix to all messages, for instance to identify the
36
 * application or the web server, then use the prefix option. Please keep in mind
37
 * the prefix is shared by all streams using syslog, as it is dependent of
38
 * the running process. For a local prefix, to be used only by one stream, you
39
 * can use the format key.
40
 *
41
 * ## Example:
42
 *
43
 * ```
44
 *        CakeLog::config('error', array(
45
 *                'engine' => 'Syslog',
46
 *                'types' => array('emergency', 'alert', 'critical', 'error'),
47
 *                'format' => "%s: My-App - %s",
48
 *                'prefix' => 'Web Server 01'
