Abstract
Abstract In order to monitor the status of a system in the form of a communications network, such as a computer local area network (LAN) 10 or an SS7 telecommunications signalling network, measurements are made of various operating parameters for each domain (S1...S14) or segment of the network. The measurements for each parameter are scaled in accordance with a respective piecewise-linear scaling function (300) for that parameter, so that all scaled measurements for all parameters have values in a range from 0 to 3, values of 1 and 2 corresponding to threshold values T1 and T2 of interest. An extreme scaled value, such as the maximum or minimum value, is selected for each parameter, and plotted on a respective one of multiple radially-extending axes (301-306), each of which is associated with a respective parameter. The plotted values are connected to form a polygonal figure (309). <IMAGE>
