Abstract

The system and method of this invention automatically manages a group of computers by automatically gathering data, storing the data, analyzing the stored data to identify specified conditions, and initiating automated actions to respond to the detected conditions. The invention, hereafter “SYSTEMWatch AI-L”, comprises a SYSTEMWatch AI-L client which turns a computer into a managed computer, a SYSTEMWatch AI-L console, which turns a computer into a monitoring computer, a SYSTEMWatch AI-L send facility, which allows a system administrator to send commands to various SYSTEMWatch AI-L clients through the SYSTEMWatch AI-L console, and a SYSTEMWatch AI-L report facility which allows a system administrator to query information collected and processed by the SYSTEMWatch AI-L clients and SYSTEMWatch AI-L consoles.

Claims

1. A method of automatically managing a computer system, wherein the method comprises:

sampling data values at time intervals, wherein each data value comprises a utilization measurement of a resource for the computer system; and

during the time interval after each data value is sampled, performing the steps of;

comparing the sampled data value to a current historical trend value;

calculating a new historical trend value based on the sampled data value and the current historical trend value; and

saving the new historical trend value as the current historical trend value.

2. The method of claim 1, wherein the sampling of data values occurs over irregular time intervals.

3. The method of claim 2, wherein the step of calculating the new historical trend value is further based on the time interval between a current sampling and a previous sampling.

4. The method of claim 1, further comprising the step of initializing a first historical trend value to a first sampled data value.

5. The method of claim 1, wherein the step of calculating the new historical trend value utilizes a recursive average filter.

6. The method of claim 1, wherein the step of calculating the new historical trend value utilizes a moving average filter.

7. A system for automatically managing a computer system, comprising:

a mechanism for sampling data values at time intervals, wherein each data value comprises a utilization measurement of a resource for the computer system;

a mechanism for comparing each data value to a current historical trend value;

a mechanism for calculating a new historical trend value each time a new data value is sampled, based on the sampled data value and the current historical trend value; and

a mechanism for saving the new historical trend value as the current historical trend value.

8. The system of claim 7, wherein the system discards each sampled data value after the new historical trend value is calculated.

9. A method of automatically managing a computer system, wherein the method comprises:

(a) sampling a data value, wherein the data value comprises a utilization measurement of a resource for the computer system at a point in time;

(b) comparing the sampled data value to a historical trend value;

(c) updating the historical trend value based on the data value and the existing historical trend value;

(d) sampling a next data value, wherein the next data value comprises a utilization measurement of a resource for the computer system at a subsequent point in time; and

(e) repeating steps (b)-(d) such that each next sampled data value is compared to the previously updated historical trend value.

10. The method of claim 9, wherein the step of updating the historical trend value further comprises the step of calculating and using a weighting factor.

11. The method of claim 10, wherein the step of calculating the weighting factor is a function of a time interval between the sampling of a past and a present data value.
