    Abstract: Systems, methods, and computer-readable media for improving debugging and troubleshooting of datacenter networks, and more particularly improving the speed of forwarding/data path related problems without going into ASIC level debugging. A switch could, for example, have a processor which communicates with an ASIC. The processor can receive flow information and a notification from the ASIC, the notification indicating a predefined error condition has been identified in a packet. The processor can modify the ASIC programming based on the notification, such that the ASIC records additional, more-detailed, flow information for the switch. The processor can then receive, from the modified ASIC, the additional flow information. The additional flow information can then be used (either by the processor or by an operator) to identify the exact reason for the errors in the flow path.

    Abstract: Systems, methods, and computer-readable media for detecting and reporting anomalies in a network environment for providing network assurance. In some embodiments, a system can determine confidence scores for at least one value of parameters of a network environment defining network events occurring in the network environment. The confidences scores can indicate a frequency that the defined network events have a specific event state. The confidence scores can be monitored to detect an anomaly in the network environment. In response to detecting the anomaly in the network environment, the system can determine a relevant network state of the network environment. The relevant network state of the network environment and the anomaly in the network environment can be presented to a user.

    Abstract: Systems, methods, and computer-readable media for clustering events occurring in a network environment for providing network assurance. In one embodiment, a system can identify event states of network events defined by values of parameters of a network environment. The system can determine a confidence score that at least one of the values of parameters is associated with a specific event state using the network events and the identified event states of the network events. The confidence score can be presented to a user for purposes of providing network assurance for the network environment.

    Abstract: Aspects of the technology provide methods for aggregating error log data between multiple devices in a network monitoring appliance. A method of the technology can include steps for identifying a plurality of operators running in a network monitoring appliance, instantiating a plurality of sensors, wherein each of the plurality of sensors is associated with a respective one of the plurality of operators, and wherein each sensor is configured to capture error log data of its corresponding operator. In some aspects, the method can further include steps for aggregating error log data from two or more of the plurality of sensors. Systems and machine-readable media are also provided.
