Techniques are described for determining one or more outlier logical paths in a computer network. A cloud-based network management system stores path data received from a plurality of network devices operating as network gateways for an enterprise network, the path data collected by each network device of the plurality of network devices for one or more logical paths of a physical interface from the network device over a wide area network (WAN). The network management system compares the path data for the plurality of logical paths to determine one or more outlier logical paths out of the plurality of logical paths. The network management system, in response to determining the one or more outlier logical paths, output a notification indicative of the one or more outlier path data out of the plurality of logical paths.
