一个小型库，帮助使用doctrine ODM在mongo数据库中存储图类型（增量统计）数据

安装

将以下内容添加到您的composer.json文件中

"require": {
    "bigtallbill/php-mongo-graph-model": "dev-master"
}

用法

// instantiate a new instance providing the doctrine DocumentManager instance
$gm = new GraphManager($dm);

$gm->setGranularity(GraphManager::MINUTE);
$gm->setWindow(GraphManager::HOUR);

// create a random statistic to store. These are instances of ParsedStat
// and can be created manually if required
$stat = $gm->parseSimpleKeyValue('system_stats', 'cpu', rand(25, 50));

// finally run an upsert using doctrine to create or update the stat
$gm->insertStat($stat);

此模型的外观

使用小时粒度和天窗口

{
    "_id" : ObjectId("5560b3b7919124c4e03710fd"),
    "date" : ISODate("2015-05-23T00:00:00.000Z"),
    "granularity" : NumberLong(3600),
    "group" : "system_stats",
    "key" : "mem",
    "window" : NumberLong(86400),
    "window_human" : "Day",
    "granularity_human" : "Hour",
    "segments" : {
        "1432400400" : NumberLong(108588),
        "1432404000" : NumberLong(119624)
    }
}

在segments键下存储每个粒度段（在我们的案例中是当前小时的顶部）。date 锁定到当前窗口的顶部（在我们的案例中是当前天）

以下是一个使用分钟粒度和小时窗口的另一个示例

{
    "_id" : ObjectId("5560c023919124c4e0371102"),
    "date" : ISODate("2015-05-23T18:00:00.000Z"),
    "granularity" : NumberLong(60),
    "group" : "system_stats",
    "key" : "processes",
    "window" : NumberLong(3600),
    "window_human" : "Hour",
    "granularity_human" : "Minute",
    "segments" : {
        "1432404000" : NumberLong(59041),
        "1432404060" : NumberLong(41138),
        "1432404120" : NumberLong(62544),
        "1432404180" : NumberLong(59392),
        "1432404240" : NumberLong(22948),
        "1432404300" : NumberLong(58825),
        "1432404360" : NumberLong(31936),
        "1432404420" : NumberLong(17407),
        "1432404480" : NumberLong(30097),
        "1432404540" : NumberLong(54094),
        "1432404600" : NumberLong(34739),
        "1432404660" : NumberLong(34164),
        "1432404720" : NumberLong(34571),
        "1432404780" : NumberLong(28592)
    }
}
