Abstract
A computer program product and a computer system for monitoring an operation status of a disconnected device by a mobile device and an audio analysis system in an infrastructure. The mobile device has connectivity to the infrastructure while the disconnected device has no connectivity to the infrastructure. The audio analysis system receives from the mobile device audio with information of a location of the mobile device. The audio analysis system determines whether the audio is recorded from the disconnected device based on the information of the location of the mobile device, compares the audio with pre-recorded sounds of the disconnected device, determines the operation status of the disconnected device, and sends to the mobile device a notification of the operation status of the disconnected device.
