Tracker
EasySwoole 提供了一個基礎(chǔ)的追蹤組件，方便用戶實(shí)現(xiàn)基礎(chǔ)的服務(wù)器狀態(tài)監(jiān)控，與調(diào)用鏈記錄。
組件要求
- php: >=7.1.0
- ext-swoole: ^4.4.0
- easyswoole/component: ^2.0
安裝方法
composer require easyswoole/tracker

調(diào)用鏈結(jié)構(gòu)說明
EasySwoole 的調(diào)用鏈跟蹤是一個以類似有序的樹狀鏈表的解構(gòu)實(shí)現(xiàn)的，解構(gòu)如下：
struct Point{
struct Point* nextPoint;
struct Point[] subPoints;
const END_SUCCESS = 'success';
const END_FAIL = 'fail';
const END_UNKNOWN = 'unknown';
int startTime;
mixed startArg;
int endTime;
string pointName;
string endStatus = self::END_UNKNOWN;
mixed endArg;
string pointId;
string parentId;
int depth = 0;
bool isNext
}基本使用

$array = \EasySwoole\Tracker\Point::toArray($point);可以把一個入口點(diǎn)轉(zhuǎn)為一個數(shù)組。例如我們可以在 MYSQL 數(shù)據(jù)庫中存儲以下關(guān)鍵結(jié)構(gòu)：
CREATE TABLE `api_tracker_point_list` (
`pointd` varchar(18) NOT NULL,
`pointName` varchar(45) DEFAULT NULL,
`parentId` varchar(18) DEFAULT NULL,
`depth` int(11) NOT NULL DEFAULT '0',
`isNext` int(11) NOT NULL DEFAULT '0',
`startTime` varchar(14) NOT NULL,
`endTime` varchar(14) DEFAULT NULL,
`status` varchar(10) NOT NULL,
PRIMARY KEY (`pointd`),
UNIQUE KEY `trackerId_UNIQUE` (`pointd`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;其余請求參數(shù)可以自己記錄。
核心字段在 pointId、parentId、isNext、status 這四個字段，例如，我想得到哪次調(diào)用鏈超時，那么就是直接
where status = fail如果想看哪次調(diào)用耗時多少，那么可以
where spendTime > 3spendTime 是通過 startTime 和 endTime 計算得出
