--- title: Logging Stack Traces layout: framework_docs objective: Adjust Laravel's logging configuration to get a full stack trace. order: 4 --- By default, we set the Logging output to use a `JsonFormatter`. This makes the log output a bit cleaner, but has the trade-off of not showing you a full stack trace. You just get the exception messages. If you need to get the full stack trace, update your `config/logging.php` file and adjust the `stderr` channel to include a `formatter_with` configuration: ```php 'stderr' => [ 'driver' => 'monolog', 'level' => env('LOG_LEVEL', 'debug'), 'handler' => StreamHandler::class, 'formatter' => env('LOG_STDERR_FORMATTER'), // JsonFormatter 'formatter_with' => [ 'includeStacktraces' => true, ], 'with' => [ 'stream' => 'php://stderr', ], ], ``` This will show you the full stack trace of logged errors when you next deploy.

'stderr' => [
    'driver' => 'monolog',
    'level' => env('LOG_LEVEL', 'debug'),
    'handler' => StreamHandler::class,
    'formatter' => env('LOG_STDERR_FORMATTER'), // JsonFormatter
    'formatter_with' => [
        'includeStacktraces' => true,
    ],
    'with' => [
        'stream' => 'php://stderr',
    ],
],
