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. The multi-cluster dashboard software system data outputs, as single user interface screen, the current health status for each of the cloud-based compute clusters.

Abstract: This disclosure describes techniques that include collecting flow data associated with communications between network devices, and determining, based on the flow data, one or more virtual networks over which the communications are taking place. In one example, this disclosure describes a system configured to perform operations comprising: storing virtual network configuration information associated with a first virtual network and a second virtual network established within a network; collecting underlay flow data associated with communications between a first server and a second server, wherein each of the first server and the second server are implemented as bare metal servers; determining, based on the underlay flow data and the stored virtual network configuration information, that the first server and the second server have communicated over the first virtual network; and generating a user interface.

Abstract: An example control plane that is executed on one or more processors in a distributed computing system is configured to receive an indication of a node to be onboarded into the distributed computing system, wherein the node comprises one of a compute node or a network device node, to discover one or more compute resources or network device resources that are associated with the node, and to assign, based on the discovery, the node to a collector that is executed in the distributed computing system, wherein the collector is configured to collect real-time telemetry data for the node during operation of the node. The control plane is further configured to receive, from the collector, the real-time telemetry data for the node that is collected by the collector, and to output, for display, a visual representation of the real-time telemetry data for the node.

Abstract: The disclosure describes techniques for network monitoring and fault localization. For example, a controller comprises one or more processors operably coupled to a memory configured to: receive a first one or more Quality of Experience (QoE) metrics measured by a first probe traversing a first path comprising one or more links; receive a second one or more QoE metrics measured by a second probe traversing a second path comprising one or more links; determine, from the first one or more QoE metrics, that the first path has an anomaly; determine, from the second one or more QoE metrics, that the second path has an anomaly; and determine, in response to determining the first path and the second path has an anomaly, based on the type of metrics and the type of links, that an intersection between the first path and the second path is a root cause of the anomaly.

Abstract: A computing system stores rule data for an application. The rule data for the application specifies characteristics of flows that occur within a network and that are associated with the application. The computing system may collect a stream of flow datagrams from the network. Additionally, the computing system may identify, based on the rule data for the application, flow datagrams in the stream of flow datagrams that are associated with the application. The computing system may generate a stream of application-enriched flow datagrams based on the identified flow datagrams. The application-enriched flow datagrams include data indicating the application. Furthermore, the computing system may process a query for results based on the application-enriched flow datagrams.
