    • A method, computer program product and apparatus for diagnosing a fault incident in a data center. A determination is made as to whether a fault incident happened in the data center. If a fault incident happened, then the business logic being executed in a node where the fault incident happened is determined. The log files associated with the execution process of the business logic is selected based on a management model corresponding to the data center, where the management model reflects the deployment and application dependency of the business logics. The fault incident is diagnosed based on the log files. The management model is utilized to select the log files associated with the execution process of the business logic, and to write information of the business logic and dependency relationships between the applications into the log file, so as to automatically, rapidly and accurately diagnose the fault incident.
    • 一种用于诊断数据中心中发生故障的方法,计算机程序产品和装置。 确定数据中心发生的故障事件是否发生。 如果发生故障事件,则确定在发生故障事件的节点中执行的业务逻辑。 与业务逻辑的执行过程相关联的日志文件基于与数据中心相对应的管理模型来选择,其中管理模型反映业务逻辑的部署和应用依赖性。 故障事件根据日志文件进行诊断。 管理模型用于选择与业务逻辑的执行过程相关联的日志文件,并将应用程序中的业务逻辑和依赖关系的信息写入日志文件中,以便自动,快速和准确地诊断故障 事件。

    • A computer implemented method and system for determining resource usage of a tenant in a multi-tenant architecture. The method includes the steps of: recording, within predetermined time intervals, total consumption of each resource in each predetermined time interval; obtaining total times of calling each operation by each tenant in each predetermined time interval; calculating consumption of each resource during each operation based on the total times and the total consumption obtained within the period of time; and calculating usage of each resource by each tenant within the period of time based on the calculated consumption of each resource during each operation and the total times of calling each operation of each tenant in each predetermined time interval. The system includes apparatus for performing the above method.
    • 一种用于确定多租户架构中的租户的资源使用的计算机实现的方法和系统。 该方法包括以下步骤:在预定时间间隔内,在每个预定时间间隔内记录每个资源的总消耗量; 在每个预定时间间隔内获得每个租户对每个操作的呼叫总时间; 根据总时间和一段时间内的总消费量,计算每次运营中每个资源的消耗量; 以及基于每个操作期间每个资源的计算消耗以及在每个预定时间间隔内呼叫每个租户的每个操作的总次数,计算每个租户在所述时间段内的每个租户的每个资源的使用。 该系统包括用于执行上述方法的装置。

    • A method and an apparatus for diagnosing memory leak. The method includes: tracing the allocation of objects; recording allocation paths and allocation time of each object; giving to each object one unique identifier (ID) corresponding to an allocation path; determining the allocation path to which each object belongs; organizing the objects which are allocated but still not collected, and counting the age generations of the objects of the similar type according to the allocation time of each object; ranking the allocation paths according to the age generations of the surviving objects; and analyzing the ranking of the allocation paths, in which the allocation path with higher rank is more probable to introduce memory leaks. Thus, the suspicious allocation path possibly incurring memory leaks is selected and reported to the user for analysis.
    • 一种用于诊断内存泄漏的方法和装置。 该方法包括:跟踪对象的分配; 记录每个对象的分配路径和分配时间; 给每个对象一个对应于分配路径的唯一标识符(ID); 确定每个对象所属的分配路径; 组织分配但尚未收集的对象,并根据每个对象的分配时间对相似类型的对象的年代进行计数; 根据幸存对象的年龄代码排列分配路径; 并且分析具有较高等级的分配路径更可能引入内存泄漏的分配路径的排序。 因此,可选择引发内存泄漏的可疑分配路径被选择并报告给用户进行分析。
