1. A method of monitoring the activity of a system, comprising:
- a) procuring a range of expected values of a time-dependent variable of the system, the range having upper and lower limits relating to expected operating parameters of the system;
b) procuring an actual value of the system'"'"'s time-dependent variable, and c) comparing the actual value with the expected range.

17. A method of monitoring the activity of a computer system, whereby system failure, overload, component failure or performance loss may be predicted, comprising:
-
a) procuring a range of expected values of a time-dependant variable of the system such as data processing speed, memory usage/allocation, network activity and storage device usage/activity, the range having upper and lower limits relating to expected operating parameters of the system, whereby a normal level of activity may be established;
b) procuring an actual and/or real-time value of the system'"'"'s time-dependent variable;
c) comparing the actual and/or real-time value with the expected range to establish whether the system is operating at a normal level of activity and, in the event that the system is found not to be operating at a normal level;
d) generating an advisory signal such as an alarm, whereby appropriate remedial action may be taken. - View Dependent Claims (18)

19. Apparatus for monitoring the activity of a system, comprising;
-
a) a range procurement element operative to procure a range of expected values of a time-dependent variable of the system, the range having upper and lower limits relating to expected operating parameters of the system, b) an actual element procurement element operative to procure an actual value of the system'"'"'s time-dependent variable, and c) a comparator element operative to compare the actual value with the expected range.

20. Apparatus for monitoring the activity of a computer system and thus to predict system failure, overload, component failure or performance loss, for example, comprising:
-
a) a range procurement element operative to procure a range of expected values of a time-dependent variable of the system such as data processing speed, memory usage/allocation, network activity and storage device usage/activity, the range having upper and lower limits relating to expected operating parameters of the computer system, whereby a normal level of activity may be established;
b) an actual value procurement element operative to procure an actual and/or real-time value of the computer system'"'"'s time dependent variable;
c) a comparator element operative to compare the actual and/or real-time value with the expected range, to establish whether the system is operating at a normal level of activity, and d) an advisory signal generator which, in the event that the system is found not to be operating at a normal level, is operative to generate an advisory signal such as an alarm, to allow appropriate remedial action to be taken.

21. A method of monitoring the activity of a system comprising:
-
procuring a range of expected values of a time-dependent variable of the system, the range having upper and lower limits relating to expected operating parameters of the system and being derived from a combination of at least two temporal models;
procuring an actual value of the system'"'"'s time-dependent variable, comparing the actual value with the expected range, and generating an advisory signal in the event that the actual value falls outside the expected range.
