The monitoring of a system

摘要

A method of monitoring a system includes providing a representative structure of the system which has a plurality of levels in a pyramidal form and selecting a part of the system which is at a level that is not a bottom most level of the pyramidal structure and which has a plurality of sections. A first section of the part of the system is chosen and the said part of the system and its sections are displayed in a graphical manner in a first panel of a display. The said first section is displayed in a second panel of the display, with a symbol in the first panel representing the said first section being shown in a differentiated manner to other graphical components representing the said part. The invention also extends to an arrangement for monitoring a system.
