    摘要： Described is a server monitoring technology that is scalable to large numbers of servers, e.g., in a datacenter. Agents on servers run queries to monitor data sources for that server, such as performance counters and other events. The agents monitor their resource usage and those of monitored events to stay within an administrator-specified resource budget (policy), e.g., by modifying the running queries and/or monitoring parameters. A controller receives results of the monitoring, analyzes the results, and takes action as needed with respect to server operation and monitoring. The controller may dynamically update an agent's queries, monitoring parameters and/or monitored data post-processing operations. The controller may issue alerts and reports, including alerts indicative of inter-server problems between two or more servers.

    摘要： The provisioning of a host computing system by a controller located over a wide area network. The host computing system has power-on code that automatically executes upon powering up, and causes the host to notify the controller of the host address. In a first level of bootstrapping, the controller instructs the host to download a maintenance operating system. The host responds by downloading and installing a maintenance operating system, enabling further bootstrapping. The persistent memory may further have security data, such as a public key, that allows the host computing system to securely identify the source of the download instructions (and subsequent instructions) as originating from the controller. A second level of bootstrapping may accomplish the configuring of the host with a hypervisor and a host agent. A third level of bootstrapping may accomplish the provisioning of virtual machines on the host.

    摘要： The present invention extends to methods, systems, and computer program products for offloading virtual machine flows to physical queues. A computer system executes one or more virtual machines, and programs a physical network device with one or more rules that manage network traffic for the virtual machines. The computer system also programs the network device to manage network traffic using the rules. In particular, the network device is programmed to determine availability of one or more physical queues at the network device that are usable for processing network flows for the virtual machines. The network device is also programmed to identify network flows for the virtual machines, including identifying characteristics of each network flow. The network device is also programmed to, based on the characteristics of the network flows and based on the rules, assign one or more of the network flows to at least one of the physical queues.

    摘要： Methods and apparatus are provided for controlling communication between a virtualized network and non-virtualized entities using a virtualization gateway. A packet is sent by a virtual machine in the virtualized network to a non-virtualized entity. The packet is routed by the host of the virtual machine to a provider address of the virtualization gateway. The gateway translates the provider address of the gateway to a destination address of the non-virtualized entity and sends the packet to the non-virtualized entity. The non-virtualized entity may be a physical resource, such as a physical server or a storage device. The physical resource may be dedicated to one customer or may be shared among customers.

    摘要： Systems and methods establish groups among numerous indications of failure in order to infer a cause of failure common to each group. In one implementation, a system computes the groups such that each group has the maximum likelihood of resulting from a common failure. Indications of failure are grouped by probability, even when a group's inferred cause of failure is not directly observable in the system. In one implementation, related matrices provide a system for receiving numerous health indications from each of numerous autonomous systems connected with the Internet. A correlational matrix links input (failure symptoms) and output (known or unknown root causes) through probability-based hypothetical groupings of the failure indications. The matrices are iteratively refined according to self-consistency and parsimony metrics to provide most likely groupings of indicators and most likely causes of failure.

    摘要： Candidates that are potentially responsible for user-perceptible network problems may be inferred. In an example embodiment, a system includes an inference engine to produce a list of candidates that are potentially responsible for user-perceptible network problems, with the candidates being network components that may include both services and network elements. A response to a service request may be a non response, an incorrect response, an untimely correct response, or a timely correct response. The user-perceptible network problems may include the untimely correct response as well as the non response and the incorrect response. In another example embodiment, a method includes monitoring a network and producing a list of candidates that are potentially responsible for user-perceptible network problems. The candidates of the list may include both services and network elements of the monitored network.
