Abstract: Disclosed systems and methods include or support a message logging service in which, responsive to receiving an event message generated by a business function, the message is logged in accordance with a message severity, one or more severity level attributes of the system, and one or more message logging criterion. Responsive to determining the message severity meets a first criterion, the message may be routed to and saved within a first persistent log file. Responsive to determining the message severity satisfies a second criterion, the message may be temporarily stored to a FIFO message queue, for possible inclusion in a second persistent log file. A health monitoring service for monitoring application programs corresponding to various business functions, upon detecting a degraded health state of a business function, may cause messages stored in the message queue to be dumped to a second persistent log file.

Abstract: An electronic device such as a head-mounted device may present extended reality content such as a representation of a three-dimensional environment. The representation of the three-dimensional environment may be changed between different viewing modes having different immersion levels in response to user input. The three-dimensional environment may represent a multiuser communication session. A multiuser communication session may be saved and subsequently viewed as a replay. There may be an interactive virtual object within the replay of the multiuser communication session. The pose of the interactive virtual object may be manipulated by a user while the replay is paused. Some multiuser communication sessions may be hierarchical multiuser communication sessions with a presenter and audience members. The presenter and audience members may receive generalized feedback based on the audience members during the presentation.
