Bridge collectors

DebugBar comes with some "bridge" collectors. This collectors provides a way to integrate other projets with the DebugBar.

Monolog

Integrates Monolog messages into the messages view.

$logger = new Monolog\Logger('mylogger');
$debugbar->addCollector(new DebugBar\Bridge\MonologCollector($logger));

Note that multiple logger can be collected:

$debugbar['monolog']->addLogger($logger);

Propel

Logs propel queries into an SQL queries view. You will need to activate Propel debug mode.

// before Propel::init()
$debugbar->addCollector(new DebugBar\Bridge\PropelCollector());

Propel::init('/path/to/config');

// after Propel::init()
// not mandatory if you set config options by yourself
DebugBar\Bridge\PropelCollector::enablePropelProfiling();

Queries can be collected on a single connection by providing the PropelPDO object to the PropelCollector as first argument.

Twig

Collects info about rendered templates. You need to wrap your Twig_Environment object into a DebugBar\Bridge\Twig\TraceableTwigEnvironment object.

$loader = new Twig_Loader_Filesystem('.');
$env = new DebugBar\Bridge\Twig\TraceableTwigEnvironment(new Twig_Environment($loader));
$debugbar->addCollector(new DebugBar\Bridge\Twig\TwigDataCollector($env));

You can provide a DebugBar\DataCollector\TimeDataCollector as the second argument of TraceableTwigEnvironment so render operation can be measured.
