show dbs; use xxxx;show collections;db.usermonitor.find();

class MongoObj {     private static $_instance;     private function __construct()     {         }

    static public function instance()     {         if(!isset(self::$_instance)){             try{                 self::$_instance = new MongoClient('mongodb://'.$_SERVER['MONGO_HOST'].':'.$_SERVER['MONGO_PORT'])             }catch(MongoConnectionException $e){                 $logger = XLogKit::logger('MongoConnection');                 //XLogKit::log_tag('');                 $logger->error('MongoConnection', $e->getMessage());             }         }         return self::$_instance;     }

    public function __clone()     {         return false;     } }
