Log

Default log

By default log files are created in {ESPO_ROOT}/data/logs/ directory.

Parameters

In data/config.php:

  'logger' => [
    'level' => 'NOTICE', // DEBUG, INFO, NOTICE, WARNING, ERROR
    'maxFileNumber' => 30,
  ],

Handlers

Actual as of v6.1.

EspoCRM uses Monolog library for logging. The library is shipped with the set of handlers. There is the ability to specify which handlers to use in Espo.

In data/config.php:

  'logger' => [
    'level' => 'NOTICE',
    'handlerList' => [
      [
        'className' => 'Espo\\Core\\Log\\Handler\\EspoRotatingFileHandler',
        'params' => [
          'filename' => 'data/logs/espo.log',
        ],
        'level' => 'NOTICE',
        'formatter' => [
          'className' => 'Monolog\\Formatter\\LineFormatter',
          'params' => [
            'dateFormat' => 'Y-m-d H:i:s',
          ],
        ],
      ],
      [
        'loaderClassName' => 'Espo\\Core\\Log\\EspoRotatingFileHandlerLoader',
        'params' => [
          'filename' => 'data/logs/test-warning.log',
        ],
        'level' => 'WARNING',
      ],
    ],
  ],

Note that it's possible to have multiple handlers.

It's possible to specify either a handler class name or loader class name. A loader class instantiates a handler class. This allows to initialize constructor parameters for a handler. It can be helpful if you need to pass some object to the handler constructor. A loader class must implement Espo\Core\Log\HandlerLoader interface. It's possible to pass dependencies (via DI mechanism) to a loader class.

Note: By specifying handlerList in the config, the default handler stops from being used.
