1. A computer monitoring system, comprising:
- a sensor to measure a parameter of a computer;
a non-volatile storage that holds an upper threshold and a lower threshold representing limits for the parameter; and
a controller configured to determine a normal operating range for the parameter and to reduce the span between the upper threshold and the lower threshold so as to match the limit of the normal operating range more closely.

Abstract
A computer monitoring system includes a sensor, a non-volatile storage and a controller. The sensor measures a parameter of a computer, and the non-volatile storage holds a threshold representing a limit for the parameter. The controller is configured to determine a normal operating range for the parameter and modify the threshold to match the limit of the normal operating range more closely.

22. A method of monitoring a computer system, comprising:
-
storing a plurality of thresholds that initially represent a manufacturer'"'"'s specification of a limit of a parameter in the computer system in a non-volatile storage, the plurality of thresholds including an upper threshold and a lower threshold;
measuring the parameter with a sensor to generate at least a first measurement;
determining a normal operating limit for the parameter in the computer system from the first measurement;
adjusting at least one of the thresholds to match the normal operating limit for the parameter more closely, including reducing the span between the upper threshold and the lower threshold;
after the threshold has been modified, measuring the parameter with the sensor to generate at least a second measurement; and
comparing the second measurement to the adjusted plurality of thresholds to determine whether the computer system is functioning abnormally.

determine a normal operating range for the parameter via direct measurement;
reduce the span between the upper threshold and the lower threshold so as to match the normal operating range more closely;
