Abstract: A system is programmed and operated to perform a method of indicating health, status, or condition of a monitored target. In certain implementations, the method involves: obtaining at least one metric associated with the monitored target; determining a level of audio degradation to be applied to a source digital media file that conveys default audio content, wherein the level of audio degradation is determined as a function of the obtained at least one metric; modifying the source digital media file in accordance with the determined level of audio degradation, resulting in modified audio data; and controlling playback of the modified audio data to serve as an audible indicator of the health, status, or condition of the monitored target.

Abstract: Various innovations for servicing of a virtual switch in a virtual networking layer are presented. The innovations include new architectures for a virtual networking layer and new operations performed when servicing a virtual switch. In some example implementations, during virtual switch servicing, interruption to actual network connectivity is minimal—below a timeout threshold that signifies failure of a network connection. Connections for a host, VMs, and physical network adapter can be maintained while the virtual switch is serviced. Although some interruption to actual network connectivity happens, apparent connectivity (for a VM) over a connection between the VM and the virtual switch can be maintained during the servicing of the virtual switch. Similarly, apparent connectivity (for a host) over a connection between the host and the virtual switch can be maintained during the servicing of the virtual switch.
