Logging

System and PHP errors are written to an application log file. For information on writing log messages or accessing log files see Kohana Log methods

The configuration file Log.php can be found in the application/config directory. If it's not there it can be copied from the system/config directory. See Configuration for more information.

There are three config settings for Logging:

$config['threshold'] = 0;
 
$config['directory'] = 'logs';
 
$config['format'] = 'Y-m-d H:i:s';

$config['threshold'] can be set at four levels:

• 0 - Logging is disabled
• 1 - error Error messages set by Kohana, including any PHP errors.
• 2 - alert Warning messages, optionally set by the application.
• 3 - info Informational messages, optionally set by the application.
• 4 - debug Debug messages, optionally set by the application, or generated by Kohana.

When set to 4 it will also log 3, 2 and 1. Lower levels are always included.

• Level 1 is recommended in production use as it will only log errors.
• Level 2 and 3 are used for custom logging by applications.
• Level 4 is useful for debugging, it will log all libraries loaded and any errors.

Kohana by default, does not log anything to level 2 or 3. Important setting the level to 4 can slow down your application significantly.

$config['directory'] log file directory, relative to application/, or absolute.

$config['format'] format for the timestamps according to date()
