Using Sentry for tracking errors in TYPO3 Flow

SentryExceptionHandler.php

use TYPO3\Flow\Error\ProductionExceptionHandler;

/**
 * Production Exception handler that reports exceptions to a configurable Sentry DSN using the raven library
 */
class SentryExceptionHandler extends ProductionExceptionHandler {

	/**
	 * @param \Exception $exception
	 * @return void
	 */
	protected function echoExceptionWeb(\Exception $exception) {
		if (isset($this->options['sentryDsn']) && strlen($this->options['sentryDsn']) > 0) {
			$ravenClient = new \Raven_Client($this->options['sentryDsn']);
			$ravenClient->captureException($exception);

		parent::echoExceptionWeb($exception);
	}
}

Settings.yaml

TYPO3:
  Flow:
    error:
      exceptionHandler:
        className: 'Your\Package\Error\SentryExceptionHandler'
        # Sentry DSN (e.g. "http://public:secret@example.com/1")
        'sentryDsn': ''

Note: Sentry is a third party tool that allows remote tracking of exceptions. See https://getsentry.com

Loading of \Raven_Client doesn't work and resulting with a PHP fatal error:
"Fatal error: Class 'Raven_Client' not found in /path/to/My.Package/Classes/My/Package/Error/SentryExceptionHandler.php on line 24"

raven package is correctly installed with composer.
any idea?

I can't test this atm because we switched to Graylog2, maybe this helps:

  TYPO3:
    Flow:
       # disable reflection for non psr-0 compliant 3rd party packages
      object:
        excludeClasses:
         'raven.raven': ['.*']

FYI via twitter:

when using „composer install -o“ instead of „composer install“, class loading of \Raven_Client works fine

the excludeClasses setting has no effect. only "composer install -o" works

FYI: I still have the autoloading issue on Flow master (3.0). It can be worked around by including the raven autoloader explicitly:

include_once Files::concatenatePaths(array(FLOW_PATH_PACKAGES, 'Libraries/raven/raven/lib/Raven/Autoloader.php'));
\Raven_Autoloader::register();
