README
Allows you to process logs using any PSR-3 compatible logger such as Monolog.
Installation
composer require "samdark/yii2-psr-log-target"
Usage
In order to use PsrTarget
you should configure your log
application component like the following:
// $psrLogger should be an instance of PSR-3 compatible logger. // As an example, we'll use Monolog to send log to Slack. $psrLogger = new \Monolog\Logger('my_logger'); $psrLogger->pushHandler(new \Monolog\Handler\SlackHandler('slack_token', 'logs', null, true, null, \Monolog\Logger::DEBUG)); return [ // ... 'bootstrap' => ['log'], // ... 'components' => [ // ... 'log' => [ 'targets' => [ [ 'class' => 'samdark\log\PsrTarget', 'logger' => $psrLogger, // It is optional parameter. The message levels that this target is interested in. // The parameter can be an array. 'levels' => ['info', yii\log\Logger::LEVEL_WARNING, Psr\Log\LogLevel::CRITICAL], // It is optional parameter. Default value is false. If you use Yii log buffering, you see buffer write time, and not real timestamp. // If you want write real time to logs, you can set addTimestampToContext as true and use timestamp from log event context. 'addTimestampToContext' => true, ], // ... ], ], ], ];
Standard usage:
Yii::info('Info message'); Yii::error('Error message');
Usage with PSR logger levels:
Yii::getLogger()->log('Critical message', Psr\Log\LogLevel::CRITICAL); Yii::getLogger()->log('Alert message', Psr\Log\LogLevel::ALERT);
Usage with original timestamp from context in the log:
// $psrLogger should be an instance of PSR-3 compatible logger. // As an example, we'll use Monolog to send log to Slack. $psrLogger = new \Monolog\Logger('my_logger'); $psrLogger->pushProcessor(function($record) { if (isset($record['context']['timestamp'])) { $dateTime = DateTime::createFromFormat('U.u', $record['context']['timestamp']); $timeZone = $record['datetime']->getTimezone(); $dateTime->setTimezone($timeZone); $record['datetime'] = $dateTime; unset($record['context']['timestamp']); } return $record; });
You can use PsrMessage instead of regular string messages to add custom context.
Standard usage:
Yii::error(new \samdark\log\PsrMessage("Critical message", [ 'custom' => 'context', 'key' => 'value', ]));
Usage with PSR logger Levels:
Yii::getLogger()->log(new \samdark\log\PsrMessage("Critical message", [ 'important' => 'context' ]), Psr\Log\LogLevel::CRITICAL);
Usage with PSR-3 log message processing:
$psrLogger = new \Monolog\Logger('my_logger'); $psrLogger->pushProcessor(new \Monolog\Processor\PsrLogMessageProcessor());
Yii::debug(new \samdark\log\PsrMessage("Greetings from {fruit}", [ 'fruit' => 'banana' ]));
