Abstract: Techniques are disclosed for a network management system (NMS) that performs quality of service (QoS) monitoring and troubleshooting of user experience issues occurring outside of a network managed by the NMS using data obtained from third-party sources. For example, an NMS obtains third-party data of a third-party application server or third-party service provider server from a third-party monitoring vendor. The NMS identifies a user experience issue indicated by the third-party data and stitches the third-party data to network data received from network devices. The NMS determines a root cause or a remedial action of the user experience issue based at least on the network data received from the one or more network devices. The NMS generates a notification for presentation to an administrator device which identifies the root cause or the remedial action of the user experience issue.

Abstract: Techniques are described for detecting that a client device physically connected to a network device is “stuck,” that is, the client device is not sending or receiving network packets with the network device. A network management system (NMS) receives current network statistics of ports of network devices with respect to client devices physically connected to the ports. The NMS identifies a candidate client device connected to a particular port of a particular network device for which the current network statistics indicate an issue. The NMS detects anomalous behavior of the candidate client device based on one or more features of the current network statistics, historical baseline statistics associated with the candidate client device, and peer statistics associated with one or more peer client devices of a same device type as the candidate client device. The NMS outputs a notification of the anomalous behavior.
