or custom / use via

return [
    'channels' => [
        'custom' => [
            'driver' => 'custom',
            'via' => \Ytake\LaravelFluent\FluentLogManager::class,
        ],
    ]
];

fluentd config sample

## match tag=local.** (for laravel log develop)
<match local.**>
  type stdout
</match>

example (production)

<match production.**>
 type stdout
</match>

and more

for lumen

fluentd config sample(lumen)

<match lumen.**>
  type stdout
</match>

Tag format

The tag format can be configured to take variables from the LogEntry object. This will then be used to match tags in fluent.

{{channel}} will be Laravel's current environment as configured in APP_ENV, NOT the logging channel from config/logging.php

{{level_name}} will be the uppercase string version of the log level.

{{level}} is the numeric value of the log level. Debug == 100, etc

You can also use variables that exist in LogEntry::$extra. Given a message like

$l = new \Monolog\LogRecord(extra: ['foo' => 'bar']);

You could use a tag format of myapp.{{foo}} to produce a tag of myapp.bar.

Monolog processors

You can add processors to the Monolog handlers by adding them to the processors array within the fluent.php config.

config/fluent.php:

'processors' => [function (\Monolog\LogRecord $record) {
    $record->extra['cloudwatch_log_group'] = 'test_group';
    
    return $record;
}],

Alternatively, you can pass the class name of the processor. This helps keep your config compatible with config:cache

config/fluent.php:

'processors' => [CustomProcessor::class],

CustomProcessor.php:

class CustomProcessor
{
    public function __invoke(\Monolog\LogRecord $record)
    {
        $record->extra['cloudwatch_log_group'] = 'test_group';

        return $record;
    }
}
