monolog 日志

1 安装 

composer require monolog/monolog


2 使用

// 创建日志服务
$logger = new Logger('my_logger’);

// 定义一个handle
$stream =  new StreamHandler(__DIR__.'/log/hello.log', Logger::DEBUG);


// 设置输出的格式 

// 默认的日期格式是 "Y-m-d H:i:s"
$dateFormat = "Y n j, g:i a";

// 输出格式
$output = "%datetime% > %level_name% > %message% %context% %extra%
";
$formatter = new LineFormatter($output, $dateFormat);
$stream->setFormatter($formatter);

// 把处理器放到对象里面 $this->handles
$logger->pushHandler($stream);


// 现在你就可以用日志服务了
$logger->info('My logger is now ready',['hello']);


// 日志格式
2020 9 25, 9:43 pm > INFO > My logger is now ready ["hello"] {"name":"brady","dummy":"Hello world!"}

3 其他日志格式 按日期 生成

$logger->pushHandler(new MonologHandlerRotatingFileHandler(__DIR__."/log/hello.log",Logger::DEBUG));


//这个会按天产生日志 hello-2020-09-01.log

[2020-09-25T21:43:34.047016+08:00] my_logger.INFO: My logger is now ready ["hello"] {"name":"brady","dummy":"Hello world!"}



logstash格式

$stream1 =  new StreamHandler(__DIR__.'/log/world.log', Logger::DEBUG);
$logstashformatter = new MonologFormatterLogstashFormatter("ml","system","test","world");
$stream1->setFormatter($logstashformatter);
$logger->pushHandler($stream1);


{"@timestamp":"2020-09-25T21:43:34.047016+08:00","@version":1,"host":"system","message":"My logger is now ready","type":"ml","channel":"my_logger","level":"INFO","monolog_level":200,"test":{"name":"brady","dummy":"Hello world!"},"world":["hello"]}




json格式


$stream2 = new MonologHandlerRotatingFileHandler("./log/wang.log");
$json = new MonologFormatterJsonFormatter();
$stream2->setFormatter($json);
$logger->pushHandler($stream2);


{"message":"My logger is now ready","context":["hello"],"level":200,"level_name":"INFO","channel":"my_logger","extra":{"name":"brady","dummy":"Hello world!"},"traceId":"trrrrrrrrr","timestamp":"2020-09-25T21:32:47.958836+0800"}ArrayArrayArray{"message":"My logger is now ready","context":["hello"],"level":200,"level_name":"INFO","channel":"my_logger","datetime":"2020-09-25T21:47:27.521873+08:00","extra":{"name":"brady","dummy":"Hello world!"},"traceId":"trrrrrrrrr"}
