#Laravel Gelf Logger

A package to send gelf logs to a gelf compatible backend like graylog. It is a Laravel wrapper for bzikarsky/gelf-php package.

#Usage

Once you have modified the Laravel logging configuration, you can use the gelf log channel as any Laravel log channel.

#Example

// Explicitly use the gelf channel
Log::channel('gelf')->debug($message, ['foo' => 'bar']);
Log::channel('gelf')->emergency($message, ['foo' => 'bar']);
 
// In case of a stack log channel containing the gelf log channel and stack
// configured as the default log channel
Log::notice($message, ['foo' => 'bar']);
 
// Using the logger helper
logger($message, $context);

#Testing

composer test
