  • Patent number: 11876699
    Abstract: A first device verification model is sent to a first agent on a first device providing at least a portion of the service. The first agent is able to monitor based on the first device verification model a parameter of the first device related to the service. A second device verification model is sent to a second agent on a second device providing at least a portion of the service, wherein the second agent is able to monitor based on the second device verification model a parameter of the second device related to the service. A report is received from the first agent of at least the parameter of the first device. A report is received from the second agent of at least the parameter of the second device. At least the parameter of the first device and at least the parameter of the second device are analyzed to determine whether the service is functioning as intended.

  • Patent number: 11805024
    Abstract: Collectors are provided to network devices of an existing computer network. A reference network type associated with the existing computer network is determined. Based at least in part on telemetry and configuration information received from the collectors and the reference network type, an intent-based network model of the existing computer network is generated.

  • Patent number: 11625293
    Abstract: A fault model representation of a computer network is generated, wherein the computer network includes a set of connected computer network elements that was at least in part configured based on a specified declarative intent in forming the computer network. A symptom representation for the computer network is determined based on telemetry data of one or more elements of the set of connected computer network elements and a behavior specification repository identifying symptoms and their associated root causes. The fault model representation and the symptom representation are provided to a root cause analysis to determine one or more root causes of one or more detected symptoms of the computer network.

  • Patent number: 11567994
    Abstract: A method for configuring a computing infrastructure is disclosed. The method comprises representing at least a portion of the computing infrastructure as a graph representation of computing infrastructure elements including a computing infrastructure node and a computing infrastructure edge, detecting a change in the graph representation of computing infrastructure elements, and determining whether the change affects a graph representation query pattern. In the event the change affects the graph representation query pattern, the change is notified to a query agent associated with the graph representation query pattern.
