An example device includes a network interface and a control unit that provides an execution environment for network performance monitoring module. The network performance monitoring monitors performance of a network between the network device and a different network device, determines, based on the monitoring, that the performance does not satisfy a performance metric, in response to the determination, performs enhanced network performance monitoring for a duration of time, and determines, based on the enhance network performance monitoring, a number of times the performance of the network transitioned between not satisfying the performance metric and satisfying the performance metric during the duration of time. The network interface transmits, to an element management system, information about the performance of the network, the information including at least the number of times the performance of the network transitioned between not satisfying and satisfying the performance metric during the duration of time.
