A shoe for analyzing a component is provided. The shoe includes a housing, a NDT probe disposed on a side of the housing, and a shoe interface. The shoe interface is disposed at the side of the housing and contacts the component during the analyzing of the component. The shoe interface separates the NDT probe from the component during the analyzing of the component and moves along the component during the analyzing of the component. The shoe also includes first and second wear indicators. The first wear indicator indicates that the shoe interface is usable during the analyzing of the component. The second wear indicator indicates that the shoe interface should be replaced. Both of the wear indicators are configured similar to the shoe interface and move along the component while the shoe analyzes the component.

A computer-implemented method, a system, and at least one computer-readable storage device are provided. A measured value related to operation of a device is periodically received for each respective reporting period. If the measured value indicates unhealthy operation of the device, a distance of the measured value from a predetermined abnormal threshold is determined and stored in a data store. Based on the determined distance, a number of most recent reporting periods included in a window is determined. All stored distances determined from measured values received before the window of the most recent reporting periods are deleted from the data store. An occurrence of a device failure is determined based on the stored distances in the data store after the deleting. In response to determining the occurrence of the device failure, an action is performed.

An attachment monitoring system according to an embodiment includes a working machine, attachments, a measurement unit, a terminal device, and a server device. The working machine includes a working arm. Each of the attachments is attached to a leading end part of the working arm so as to be driven by a fluid pressure. The measurement unit is provided to measure at least one of a vibration and the fluid pressure when each of the attachments identified on the basis of individual identifying information is driven. The terminal device is provided in the working machine to acquire measured results of the measurement unit. The server device collects the measured results of the respective attachments from the terminal device, and analyzes operation states of the respective attachments on the basis of the collected measured results.
