README

Wrapper for Zend/Logger/Log which allows users to track exceptions, add default "extra" attributes, automatic injection of mail transport for the mail writer and automatic mongoClient injection from doctrine odm for the mongo writer. Inspired by eddiejaoude/zf2-logger.

Installation

Composer

• Install Composer
• Install the module using Composer into your application's vendor directory. Add the following line to your composer.json.

{
   "require": {
       "vcomedia/vco-zf-logger": "dev-master"
   }
}

• Execute composer update
• Enable the module in your ZF2 application.config.php file.

return array(
    'modules' => array(
        'VcoZfLogger'
    )
);

• Copy and paste the vco-zf-logger/config/module.vco-zf-logger.local.php.dist file to your config/autoload folder and customize it with your configuration settings. Make sure to remove .dist from your file. Your module.vco-zf-logger.local.php might look something like the following:

<?php

  'VcoZfLogger' => array(

                          'suppress' => true
                      )
                  )
              )
          )
      )
  )
);

Note: The configuration array returned by the top level 'VcoZfLogger' key is passed directly into the Log class constructor with the exception of the mail transport and mongo credential injection which are both optional.

• To access your logger and log a message, you can do something like so:

$logger = $this->getServiceLocator()->get('VcoZfLogger');
$logger->log(\Zend\Log\Logger::INFO, 'Some message to log.');

• To add additional 'extra' parameters to all logged messages, add the following to onBootstrap method in Module.php:

   public function onBootstrap (MvcEvent $e) {
       $eventManager = $e->getApplication()->getEventManager();
       $moduleRouteListener = new ModuleRouteListener();
       $moduleRouteListener->attach($eventManager);
       
       $sm = $e->getApplication()->getServiceManager();
       $logger = $sm->get('VcoZfLogger');
       $logger->addDefaultExtra(array('foo' => 'bar'));
   }

• Note: The following 'extra' parameters are added by default to all logged messages:

        $defaultExtra = array(
           'sessionId' => session_id(),
           'host'      => !empty($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : 'CLI',
           'ip'        => !empty($_SERVER['REMOTE_ADDR']) ? $_SERVER['REMOTE_ADDR'] : 'unavailable'
       );

• You can remove default 'extra' options or set your own at once using setDefaultExtra method:

    public function onBootstrap (MvcEvent $e) {
        $eventManager = $e->getApplication()->getEventManager();
        $moduleRouteListener = new ModuleRouteListener();
        $moduleRouteListener->attach($eventManager);
        
        $sm = $e->getApplication()->getServiceManager();
        $logger = $sm->get('VcoZfLogger');
        $logger->setDefaultExtra(array());
    }

• Instead of using VcoZfLogger as logger service name, usa an alias for decoupling:

i.e.

    //...
    'aliases'    => array(
        'Logger' => 'VcoZfLogger'
    ),
    //...

Then your usage in your code becomes...

    //...
    $serviceLocator->get('Logger')->emerg('Emergency message');
    //...

• You can easily inject a logger into any service by implmenting the LoggerAwareInterface:

i.e.

    //...
    /**
     * Set logger instance
     *
     * @param LoggerInterface
     * @return void
     */
    public function setLogger(LoggerInterface $logger);
    //...
