Requirements

TYPO3.CMS 7.6+

Your project set up with composer and `monolog/monolog` as requirement.

"config": {
        "vendor-dir": "Packages/Libraries",
        "bin-dir": "bin"
},
{
  "repositories": [
        {
          "type": "composer",
          "url": "http://composer.typo3.org/"
        },
        {
          "url": "https://github.com/georgringer/logging.git",
          "type": "git"
        }
  ],
  "require": {
        "typo3/cms": "7.1",
        "georgringer/logging": "dev-master",
        "monolog/monolog": "*"
  }
}

It might be possible that a later release will bring support for 6.2 LTS.

Installation

Install the extension as always. Currently (state of 7.2), packages installed via composer are automatically loaded. For 6.2 LTS, set the environment variable TYPO3_COMPOSER_AUTOLOAD to 1, e.g. in your .htaccess:

SetEnv TYPO3_COMPOSER_AUTOLOAD 1

Configuration

The configuration can be added to your `typo3conf/AdditionalConfiguration.php` file. The API is inspired by the current Logging framework of TYPO3 CMS.

The following logging levels are available:

* Debug (100)
* Info (200)
* Notice (250)
* Warning (300)
* Error (400)
* Critical (500)
* Alert (550)
* Emergency (600)

Simple file logger

This is the configuration of a simple file logger which is written to `typo3temp/out.log`.

$GLOBALS['TYPO3_CONF_VARS']['MONOLOG'] = array(
        'handlerConfiguration' => array(
                'name' => 'General',
                'handlers' => array(
                        \Monolog\Handler\StreamHandler::class => array(
                                'configuration' => array(
                                        PATH_site . 'typo3temp/out.log',
                                        \Monolog\Logger::ERROR
                                )
                        )
                )
        )
);

Every call will be logged where the level is at least ERROR (400).

Important: Take care if logging to a file which is available in a public directory with no access restriction!!

Log to the database

Sometimes it makes sense to log to the database. You can do that with the following configuration:

$GLOBALS['TYPO3_CONF_VARS']['MONOLOG'] = array(
        'processorConfiguration' => array(
                \GeorgRinger\Logging\Log\Monolog\Processor\Typo3Processor::class => array()
        ),
        'handlerConfiguration' => array(
                'name' => 'General',
                'handlers' => array(
                        \GeorgRinger\Logging\Log\Monolog\Handler\DatabaseHandler::class => array()
                )
        )
);

The Typo3Processor will add additional information to the log entry:

An internal process id of TYPO3 which will allow to filter all log entries within a single request

The IP of the client

The TYPO3 mode which is either BE, FE or CLI

The ID of an existing backend or frontend user

Combined example

The logging framework allows to combine multiple handlers. Logging helps you not only while building a website or application but also during its whole lifetime! Especially on production sites it is likely that you can't use commands like print_r or die().

You might ignore debugging information, write warnings to a file and send errors via mail to yourself:

$GLOBALS['TYPO3_CONF_VARS']['MONOLOG'] = array(
        'processorConfiguration' => array(
                \GeorgRinger\Logging\Log\Monolog\Processor\Typo3Processor::class => array()
        ),
        'handlerConfiguration' => array(
                'name' => 'General',
                'handlers' => array(
                        \Monolog\Handler\NativeMailerHandler::class => array(
                                'configuration' => array(
                                        'admin@example.org',
                                        'Error from website',
                                        'no-reply@example.org',
                                        \Monolog\Logger::ERROR
                                ),
                        ),
                        \Monolog\Handler\StreamHandler::class => array(
                                'configuration' => array(
                                        PATH_site . 'typo3temp/out.log',
                                        \Monolog\Logger::WARNING
                                ),
                        ),
                        \Monolog\Handler\SocketHandler::class => array(
                                'configuration' => array(
                                        'tcp://127.0.0.1:7000'
                                ),
                                'formatter' => array(\Monolog\Formatter\LogstashFormatter::class, array('Application', 'System')),
                        ),
                )
        )
);

Loggers depending on class called

As in the current logging framework of TYPO3 CMS it is also with this extension possible to configure a different logging behaviour for different classes. An example would be to log all warnings to a file but for one important extension those warnings should also be sent as email.

Therefore, add the namespace of the specific extension to the logging configuration:

$GLOBALS['TYPO3_CONF_VARS']['MONOLOG'] = array(
        'handlerConfiguration' => array(
                'name' => 'General',
                'handlers' => array(
                        \Monolog\Handler\StreamHandler::class => array(
                                'configuration' => array(
                                        PATH_site . 'typo3temp/out.log',
                                        \Monolog\Logger::WARNING
                                )
                        )
                )
        )
);
$GLOBALS['TYPO3_CONF_VARS']['MONOLOG']['GeorgRinger']['Shop'] = array(
        'handlerConfiguration' => array(
                'name' => 'Important Extension',
                'handlers' => array(
                        \Monolog\Handler\NativeMailerHandler::class => array(
                                'configuration' => array(
                                        'admin@example.org',
                                        'Error from website',
                                        'no-reply@example.org',
                                        \Monolog\Logger::WARNING
                                )
                        ),
                        \Monolog\Handler\StreamHandler::class => array(
                                'configuration' => array(
                                        PATH_site . 'typo3temp/out.log',
                                        \Monolog\Logger::WARNING
                                )
                        )
                )
        )
);

In the example above, every logging call within the namespace of GeorgRinger\Shop will trigger the 2nd configuration. All other calls will be handled by the first configuration.

How to log

Logging is very simple and similar to the used logging framework:

/** @var \Monolog\Logger $logger */
$logger = GeneralUtility::makeInstance(\GeorgRinger\Logging\Log\MonologManager::class)->getLogger(__CLASS__);
$logger->info('Some text', array('additional information' => 123));

Available methods for logging

The following methods are available for logging. The context is an optional array with additional information.

Debug

$logger->addDebug($message, $context);
$logger->debug($message, $context);

Info

$logger->addInfo($message, $context);
$logger->info($message, $context);

Notice

$logger->warn($message, $context);

Error

$logger->addError($message, $context);
$logger->err($message, $context);
$logger->error($message, $context);

Critical
