When configuring adapters, you may specify one or more priorities for each, using the
'priority' key. This key can be a single priority level (string), or an array of multiple
levels. When a log message is written, all adpaters that are configured to accept the priority
level with which the message was written will receive the message.
{{{
Logger::config(array(
'default' => array('adapter' => 'Syslog'),
'badnews' => array(
'adapter' => 'File',
'priority' => array('emergency', 'alert', 'critical', 'error')
)
));
}}}
In the above configuration, all messages will be written to the system log (syslogd), but only
messages with the priority error or higher will be logged to a file. Messages can then be
written to the log(s) using the write() method:
{{{ Logger::write('alert', 'This is an alert-level message that will be logged in 2 places'); }}}
Messages can also be written using the log priorty as a method name:
{{{ Logger::alert('This is an alert-level message that will be logged in 2 places'); }}}
This works identically to the above. The message priority levels which Logger supports are as
follows: emergency, alert, critical, error, warning, notice, info and debug.
Attempting to use any other priority level will raise an exception. See the list of available
adapters for more information on what adapters are available, and how to configure them.
