Abstract: This disclosure describes techniques that determine device connectivity in the absence of a network layer 2 discovery protocol such as Link Layer Discovery Protocol (LLDP). In one example, this disclosure describes a method that includes retrieving, from a bridge data store of a bridge device on a network having one or more host devices, a plurality of first interface indexes, wherein each first interface index corresponds to a network interface of network interfaces of the bridge device; retrieving, from the bridge data store, remote network addresses corresponding to the network interfaces of the bridge device, each remote network address of the remote network addresses corresponding to a second interface index; selecting a remote network address having a second interface index that matches the first interface index; determining a host device having the selected remote network address; and outputting an indication that the bridge device is coupled to the host device.

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 underlay flow data along with overlay flow data within a network and correlating the data to enable insights into network operation and performance. In one example, this disclosure describes a method that includes collecting flow data for a network having a plurality of network devices and a plurality of virtual networks established within the network; storing the flow data in a data store; receiving a request for information about a data flow, wherein the request for information specifies a source virtual network for the data flow and further specifies a destination virtual network for the data flow; and querying the data store with the specified source virtual network and the specified destination virtual network to identify, based on the stored flow data, one or more network devices that have processed at least one packet in the data flow.

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 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.
