README

该库主要通过设置traceid,spanid,来实现日志链路记录,保证同一请求的链路traceid一致;
并且增加RedisHandler可以将日志直接记录到redis中(协程方式),后续可以通过ELK同步日志;另外通过日志配置增加version、interface、method、params、cost(时间消耗)的日志记录
{"messages":"trace[HttpTraceMiddleware.php:53] HTTP END","level":200,"level_name":"info","channel":"swoft","event":"request","tid":14,"cid":14,"traceid":"5dcb6271b889c","spanid":"","version":"","interface":"\/user\/info","method":"GET","params":[],"appInfo":{"env":"local","name":null,"version":null},"cost":"231.90ms","datetime":"2019-11-13 09:54:57.855"}

要求

该库的日志记录级别为info,请打开相关日志级别记录。

用法

composer require nango/swoft-tracker

配置

bean.php文件中进行配置;

如果应用只提供RPC服务,则需要在bean.php中添加,RPC中间件来记录相关日志;如下:

//RPC中间件
'serviceDispatcher' => [
    'middlewares'      => [
        SwoftTracker\Middleware\RpcTraceMiddleware::class
    ],
],

如果应用需要对外提供HTTP服务,并且内部需要通过RPC调用其他微服务的话,则需要在bean.php中进行以下配置:

首先增加HTTP中间件:

'httpDispatcher'    => [
    'middlewares'      => [
        SwoftTracker\Middleware\HttpTraceMiddleware::class
    ],
],

另外,RPC CLient增加extender配置:

'user'              => [
    'class'   => ServiceClient::class,
    'host'    => '192.168.152.55',
        ... ...
    'packet'  => bean('rpcClientPacket'),
    'extender' => bean(SwoftTracker\Middleware\TraceExtender::class)
],

以上配置就可以实现,多服务之间调用时的日志链路追踪。

logger配置

使用RedisHandler,可以指定连接池,将业务redis库和日志库隔离开;简单配置如下:

    'applicationHandler' => [
        'class'     => SwoftTracker\Middleware\RedisHandler::class,
        'redisPool' => 'redis.log-pool',
        'levels'    => 'info,error,warning',
    ],

    //可以在logger配置中增加items选项来设置日志记录消耗时间,RPC请求方法等;
    'logger'             => [
        'flushRequest' => false,
        'enable'       => true,
        'json'         => true,
        'items'        => [
            'traceid',
            'spanid',
            'version',
            'interface',
            'method',
            'params',
            'appInfo',
            'cost'
        ],
    ],
    

非swoft框架 RPC调用

如果需要在非swoft框架中通过RPC调用swoft的微服务的话,需要在ext中增加traceid参数,如下:

$traceid = uniqid();
$req = [
        "jsonrpc" => '2.0',
        "method" => sprintf("%s::%s::%s", $version, $class, $method),
        'params' => [12,'type'],
        'id' => '',
        'ext' => ['traceid' => $traceid],
    ];
//发起调用
... ...
