In one embodiment, a method includes receiving received signal strength data, computing an aggregate square error surface based on the received signal strength data, computing a probability surface by applying a probability density function to the aggregate error surface, and computing a mean location of a wireless node. Using this data, a prioritized list of suspect components for the IT system is generated. The data processing system is coupled to a hardware management console. In addition, the antenna is a loop antenna formed in a loop shape. The pipe is elastically deformable in a radial direction with changeable diameters and has a gap extending in a straight line along a circumferential line of the pipe over its entire length. The interface also includes a scanning module that cooperates with the data enumeration module to change the view from the stored first datum to another datum.
