Abstract: This disclosure describes techniques for monitoring, scheduling, and performance management for virtualization infrastructures within networks. In one example, a computing system includes a plurality of different cloud-based compute clusters (e.g., different cloud projects), each comprising a set of compute nodes. Policy agents execute on the compute nodes to monitor performance and usage metrics relating to resources of the compute nodes. Policy controllers within each cluster deploy policies to the policy agents and evaluate performance and usage metrics from the policy agents by application of one or more rulesets for infrastructure elements of the compute cluster. Each of the policy controllers outputs data to a multi-cluster dashboard software system indicative of a current health status for the infrastructure elements based on the evaluation of the performance and usage metrics for the cluster.

Abstract: A variety of different graphical user interfaces are generated that when displayed provide a visual and interactive representation of one or more performance metrics associated with the operation of a computer network. The graphical user interfaces may be used to monitor the underlay computer network for a virtualization infrastructure, as one example. Aspects include grouping the servers of a computer network into a plurality of aggregates, each aggregate comprising one or more servers. A set of probes are configured that are issued by an agent of a server in one aggregate and sent through the computer network to one or more agents in the server(s) of a different aggregate. Responses and other measurements taken based on the issuance of the probes is gathered and analyzed to generate metrics that are then used to generate, at least in part, the information provided in the graphical user interfaces.

Abstract: A policy controller executes algorithms to operate on a list of devices forming a computer network to generate outputs including one or more graphic user interfaces. The graphic user interfaces, when displayed on a display device, provide various versions of a visual representation of a network topology for the actual computer network or a computer network being modeled. The graphic user interfaces include graphic symbols representative of various devices included in the computer network that are arranged into one or more radial arrangements. The graphic user interfaces include graphic lines indicative of the physical interconnections between the devices, the graphic lines extending across the radial arrangement(s) and extending between the graphic symbols representative of devices to provide a visual representation of the interconnections that communicatively couple the devices.

Abstract: The present invention addresses the need for improved virtualized cloud infrastructure policy implementation and management in order allow real-time monitoring and optimization of virtualized resources. It provides systems and methods for real-time cloud infrastructure policy implementation and management that include a plurality of host devices, a plurality of real-time probe agents associated with the plurality of host devices operating on each of the plurality of host devices, and a policy engine communicatively coupled to the plurality of host devices and containing a policy associated with an application program deployed in at least one of the plurality of host devices. The policy engine is programmed to monitor in real time changes in deployment of the application program across the plurality of host devices and to push the policy to the real-time probe agent operating on each host device on which the application program is deployed.

Abstract: This disclosure describes techniques for presenting information about a network, virtualization infrastructure, cluster, or other computing environment, and may involve presentation of user interfaces that may enable nuanced, unique, and/or comprehensive insights into how infrastructure elements and computing resources are being used and information about patterns of usage and/or utilization. This disclosure also describes techniques for communicating, within a computing system, information used to create, update, and/or modify the user interfaces that present information about a network, virtualization infrastructure, cluster, or other computing environment.

Abstract: This disclosure describes techniques for analyzing information generated as a result of monitoring resources within computing environments. In one example, this disclosure describes a method that includes observing a plurality of alerts generated in response to monitoring resources associated with a plurality of connected elements within a network; determining a plurality of occurrence counts; determining a plurality of concurrent occurrence counts, wherein each of the plurality of concurrent occurrence counts represents a count of concurrent occurrences of two or more of the alerts in the set of historical alerts; and identifying one or more root cause alerts, wherein the one or more root cause alerts are determined based on the plurality of occurrence counts and the plurality of the concurrent occurrence counts, and wherein the one or more root cause alerts are a subset of the plurality of alerts.

Abstract: Techniques for presenting information about a network, virtualization infrastructure, cluster, or other computing environment, which may involve presentation of user interfaces that may enable nuanced, unique, and/or comprehensive insights into how infrastructure elements, instances, and/or computing resources are being used and information about patterns of usage and/or utilization. Techniques for communicating, within a computing system, information used to create, update, and/or modify the user interfaces that present information about a network, virtualization infrastructure, cluster, or other computing environment. Techniques in accordance with one or more aspects of the present disclosure may involve use of separate interfaces for collecting or accessing data used to draw a user interface that presents information about a network, and for collecting or receiving data used to update the user interface as changes occur to the utilization of infrastructure elements represented within the user interface.

Abstract: A computing system includes a computing device configured to execute a plurality of virtual machines, each virtual machine of the plurality of virtual machines configured to provide control plane functionality for at least a different respective subset of forwarding units of a network device, the computing device distinct from the network devices. The computing system also includes a policy agent configured to execute on the computing device. The agent is configured to determine that a particular virtual machine of the plurality of virtual machines provides control plane functionality for one or more forwarding units of the network device; determine control plane usage metrics for resources of the particular virtual machine; and output, to a policy controller, data associated with the control plane usage metrics and data associating the particular virtual machine with the one or more forwarding units for which the particular virtual machine provides control plane functionality.
