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.

It uses the new Laravel custom log channel introduced in Laravel 5.6.

A gelf receiver like graylog2 must be configured to receive messages with a GELF UDP, TCP or HTTP Input.

Installation

Install via composer

composer require hedii/laravel-gelf-logger

Edit config/logging.php to add the new gelf log channel.

return [
    'default' => env('LOG_CHANNEL', 'stack'),

    'channels' => [
        // You can use the gelf log channel with the stack log channel
        'stack' => [
            'driver' => 'stack',
            'channels' => ['daily', 'gelf'],
        ],

        // other log channels...

        'gelf' => [
            'driver' => 'custom',

            'via' => \Hedii\LaravelGelfLogger\GelfLoggerFactory::class,

            // This optional option determines the processors that should be
            // pushed to the handler. This option is useful to modify a field
            // in the log context (see NullStringProcessor), or to add extra
            // data. Each processor must be a callable or an object with an
            // __invoke method: see monolog documentation about processors.
            // Default is an empty array.
            'processors' => [
                \Hedii\LaravelGelfLogger\Processors\NullStringProcessor::class,
                // another processor...
            ],

            // This optional option determines the minimum "level" a message
            // must be in order to be logged by the channel. Default is 'debug'
            'level' => 'debug',

            // This optional option determines the channel name sent with the
            // message in the 'facility' field. Default is equal to app.env
            // configuration value
            'name' => 'my-custom-name',

            // This optional option determines the system name sent with the
            // message in the 'source' field. When forgotten or set to null,
            // the current hostname is used.
            'system_name' => null,

            // This optional option determines if you want the UDP, TCP or HTTP
            // transport for the gelf log messages. Default is UDP
            'transport' => 'udp',

            // This optional option determines the host that will receive the
            // gelf log messages. Default is 127.0.0.1
            'host' => '127.0.0.1',

            // This optional option determines the port on which the gelf
            // receiver host is listening. Default is 12201
            'port' => 12201,

            // This optional option determines the path used for the HTTP
            // transport. When forgotten or set to null, default path '/gelf'
            // is used.
            'path' => null,

            // This optional option determines the maximum length per message
            // field. When forgotten or set to null, the default value of 
            // \Monolog\Formatter\GelfMessageFormatter::DEFAULT_MAX_LENGTH is
            // used (currently this value is 32766)
            'max_length' => null,

            // This optional option determines the prefix for 'context' fields
            // from the Monolog record. Default is null (no context prefix)
            'context_prefix' => null,

            // This optional option determines the prefix for 'extra' fields
            // from the Monolog record. Default is null (no extra prefix)
            'extra_prefix' => null,
        ],
    ],
];

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
