Abstract: A system generates session replays that capture event data representing user actions performed with an online application. A session replay is configured to be associated with events of a trigger event type. A display of a user interface of the online application is displayed via a client device. The system stores event data describing user actions performed via the user interface of the online application in a replay data store. The replay data store retains event data representing user actions performed within a recent time interval. The system detects an occurrence of a trigger event of the trigger event type and extracts session replay data representing user actions performed with the online application via the client device within a threshold time prior to the trigger event. The session replay data is sent for display via a dashboard user interface.

Abstract: Examples described herein relate to a method for reconfiguring a beacon by an access point (AP) to minimize or avoid network outages experienced by client devices connected to the AP. The AP transmits a beacon comprising a basic service set identifier (BSSID) field and a Multiple BSSID (MBSSID) element. The MBSSID element corresponds to an MBSSID set comprising a transmitted BSSID associated with a transmitted virtual access point (VAP) and a non-transmitted BSSID associated with a non-transmitted VAP, where the BSSID field in the beacon is set to the transmitted BSSID. Further, the AP reconfigures the beacon to generate a reconfigured beacon upon determining that the transmitted VAP is non-functional. In particular, the BSSID field in the reconfigured beacon is set to the non-transmitted BSSID of the MBSSID set. Moreover, the AP transmits the reconfigured beacon to the client device.
