1. A method comprising:
identifying, by a network management system (NMS) that manages a plurality of access point (AP) devices in a wireless network, an area in the wireless network that represents a potential coverage hole in the wireless network, wherein the area representing the potential coverage hole comprises at least two neighboring AP devices of the plurality of AP devices that are each associated with one or more service level expectation (SLE) metrics indicative of an issue in the wireless network;
determining, by the NMS, a root cause of the issue in the wireless network;
performing, by the NMS, one or more actions to address the root cause of the issue in the wireless network; and
determining, by the NMS and based on determining that the performance of the one or more actions does not resolve the root cause of the issue in the wireless network, that the area that represents the potential coverage hole in the wireless network represents a true coverage hole in the wireless network.
