    Abstract: A virtual-machine environment can include a parent component (e.g., a host cluster, a host or a set of virtual machines) that is a parent to a set of two or more child components. For example, a host cluster can be a parent to multiple hosts; a host can be a parent to multiple virtual machines; and a set of virtual machines can be a parent to multiple virtual machines. Performance metrics for the child components can be monitored. A child-component performance state can be determined for each child component in the set of two or more child components using a corresponding monitored performance metric and a child-component state criterion (e.g., that maps performance-metric values to states). A parent performance state can be determined for the parent component using the child-component performance state for each child component in the set and a parent-component state criterion.

    Abstract translation: 虚拟机环境可以包括父组件（例如，主机集群，主机或一组虚拟机），其是两个或多个子组件的集合的父级。 例如，主机集群可以是多个主机的父级; 主机可以是多个虚拟机的父级; 并且一组虚拟机可以是多个虚拟机的父级。 可以监视子组件的性能指标。 可以使用对应的监视的性能度量和子组件状态标准（例如，将性能度量值映射到状态）来确定两组或更多子组件中的每个子组件的子组件性能状态。 可以使用组中的每个子组件的子组件性能状态和父组件状态标准来为父组件确定父性能状态。

    Abstract: A scheduler manages execution of a plurality of data-collection jobs, assigns individual jobs to specific forwarders in a set of forwarders, and generates and transmits tokens (e.g., pairs of data-collection tasks and target sources) to assigned forwarders. The forwarder uses the tokens, along with stored information applicable across jobs, to collect data from the target source and forward it onto an indexer for processing. For example, the indexer can then break a data stream into discrete events, extract a timestamp from each event and index (e.g., store) the event based on the timestamp. The scheduler can monitor forwarders' job performance, such that it can use the performance to influence subsequent job assignments. Thus, data-collection jobs can be efficiently assigned to and executed by a group of forwarders, where the group can potentially be diverse and dynamic in size.

    Abstract translation: 调度器管理多个数据收集作业的执行，向一组转发器中的特定转发器分配各个作业，并且生成并发送令牌（例如，数据收集任务对和目标源对）到分配的转发器。 转发器使用令牌，以及适用于作业的存储信息，从目标源收集数据，并将其转发到索引器进行处理。 例如，索引器然后可以将数据流中断为离散事件，从每个事件中提取时间戳并基于时间戳索引（例如，存储）事件。 调度程序可以监视转发器的作业性能，使其可以使用性能来影响后续的作业分配。 因此，数据收集作业可以被有效地分配给一组转发器并且由一组转发器执行，其中该组可以在大小上潜在地多样化和动态化。

    Abstract: Techniques promote monitoring of hypervisor systems by presenting dynamic representations of hypervisor architectures that include performance indicators. A reviewer can interact with the representation to progressively view select lower-level performance indicators. Higher level performance indicators can be determined based on tower level state assessments. A reviewer can also view historical performance metrics and indicators, which can aid in understanding which configuration changes or system usages may have led to sub-optimal performance.

    Abstract: The disclosed embodiments relate to a system for monitoring a virtual-machine environment. During operation, the system assigns a task, corresponding with a task request, to a first virtual machine. The performance of the task at the first virtual machine is monitored. Based on the monitoring, it is determined whether the performance of the task at the first virtual machine is unsatisfactory. If so, the task is automatically reassigned to a second virtual machine.
