摘要： A method and system for managing a service level of a service provided by a service provider to a customer under a service level agreement. The actual measurement data is adjudicated to correct the measurement data in accordance with at least one adjudication element that provides information relating to how to correct the measurement data. The adjudicated measurement data is transformed into operational data by being reorganized into one or more groups of data. The operational data is evaluated by applying a formula to the operational data, resulting in the operational data being configured for being subsequently qualified. The operational data is qualified by comparing the evaluated operational data with specified service level targets for at least one service level period and identifying operational data points meeting and/or not meeting the specified service level targets.

摘要： a virtual storage module operable to run in a virtual machine monitor may include a wait-queue operable to store incoming block-level data requests from one or more virtual machines. In-memory metadata may store information associated with data stored in local persistent storage that is local to a host computer hosting the virtual machines. The data stored in local persistent storage replicates a subset of data in one or more virtual disks provided to the virtual machines. The virtual disks are mapped to remote storage accessible via a network connecting the virtual machines and the remote storage. A cache handling logic may be operable to handle the block-level data requests by obtaining the information in the in-memory metadata and making I/O re-quests to the local persistent storage or the remote storage or combination of the local persistent storage and the remote storage to service the block-level data requests.

摘要： A system and method for visualizing data in two-dimensional time-space diagrams including generating multi-dimensional program trace files, converting and merging them into interval trace files, and generating multiple time-space diagrams (multiple Gantt charts) to visualize the resulting multi-dimensional interval trace files. The needed events and trace information required to form multi-dimensional event traces are described in event trace files typically gathered from running programs, such as parallel programs for technical computing and Web server processes. The method includes converting event traces into interval traces. In one selectable design, the two-dimensional time-space diagrams includes three discriminator types (thread, processor, and activity) and six discriminator-legend combinations, capable of producing seven possible views. The six discriminator-legend combinations are thread-activity, thread-processor, processor-thread, processor-activity, activity-thread, and activity-processor. Each discriminator-legend combination corresponds to one time-space diagram, except that the thread-activity combination has two possible views: Thread-Activity View and Connected Thread-Activity View.
摘要翻译：一种用于在二维时空图中可视化数据的系统和方法，包括生成多维程序跟踪文件，将其转换并合并到间隔跟踪文件中，以及生成多个时空图（多个甘特图），以便可视化所得到的多重维间隔跟踪文件。形成多维事件跟踪所需的事件和跟踪信息在通常从运行程序中收集的事件跟踪文件中描述，例如用于技术计算和Web服务器进程的并行程序。该方法包括将事件跟踪转换为间隔跟踪。在一个可选择的设计中，二维时空图包括三个鉴别器类型（线程，处理器和活动）以及六个鉴别器 - 图例组合，能够产生七个可能的视图。六个鉴别器 - 图例组合是线程活动，线程处理器，处理器线程，处理器活动，活动线程和活动处理器。每个鉴别器图例组合对应于一个时空图，除了线程活动组合有两个可能的视图：线程活动视图和已连接的线程活动视图。
