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 T.sub.1 and T.sub.2 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).
