This is a relatively simple Logger Module for ZF2. It attaches to the 'log' event allowing it to capture logging events from any module that triggers that event.

The logger class has the following configuration values available to it under the logger key as shown:

  array(
	  'logger' => array(
		  'db_adapter' => null,
		  'logger_table' => 'application_log',
		  'priority_filter' => Logger::DEBUG,
		  'log_file' => '/tmp/application.log'
	  )
  );

• db_adapter is the database adapter to use (i.e. Zend\Db\Adapter\Adapter or such) if logging to a database
• logger_table is the table we are writing log entries to (schema is in sql/create.sql)
• priority_filter the priority to filter against when writing log entries
• log_file the file on the local file system to log events to

To use the logger, you can trigger a 'log' event, for example as shown below from a class which implements the ServiceLocatorAwareInterface:

  $eventManager = $this->getServiceLocator()->get('Application')->getEventManager();
  $eventManager->trigger('log', $this, array('message' => "Testing Logging", 'priority' => Logger::ERR));

Alternatively, the Logger module comes with a Logger\LoggerTrait trait which can be used (provides a logEvent(<message>, <priority>) method which can be used in any class that provides the ServiceLocatorAwareInterface.
