Abstract

Optimizing of performance data in a data processing system is provided by the use of data filters and alarms. Statistics to be monitored are a conglomeration of both system statistics and statistics made available by application programs, both on local and remote data processing systems. The statistics are filtered using combinations of arithmetic and boolean operators. A single filtered condition can invoke multiple alarm responses, and multiple alarm conditions can trigger the same alarm response. Feedback of filtered statistics is provided so that such statistics can be monitored and recorded in the same manner as normal system statistics.

Claims

1. A computer-implemented method for monitoring performance of a computer system, the computer system having at least one host, a display, processor, memory and user controls, comprising the steps of:

(a) dynamically receiving during operation of said computer system at least one expression defining at least one new statistic, said expression comprising at least one mathematical operator and at least one of a set of existing performance statistics generated by said computer system;

(b) reading from said memory said at least one existing performance statistic contained in said expression;

(c) filtering, by said processor, said at least one existing performance statistic to generate said new statistic;

(d) adding said new statistic to said set of existing performance statistics in said memory so that at least one program running on said computer system can utilize said new statistic, wherein said new statistic becomes one of said existing performance statistics;

(e) dynamically receiving a second expression defining a second new statistic, said second expression comprising at least said new statistic and a second mathematical operator; and

(f) repeating steps (b) through (d), wherein said at least one performance statistic comprises said new statistic.

2. The method of claim 1 wherein said existing performance statistics comprises statistics from local and remote data processing systems.

3. The method of claim 1 wherein said filtering step comprises the step of performing boolean and arithmetic operations on said existing performance statistic.

4. The method according to claim 1 further comprising the steps of:

testing said generated new statistic; and

generating at least one alarm condition in response to said testing step.

5. The method of claim 4 wherein said alarm condition invokes an alarm response.

6. The method of claim 5 wherein said alarm response initiates a process.

7. The method of claim 5 wherein said alarm response initiates sending of a signal.

8. The method of claim 5 wherein said alarm response initiates a visual indicator on said display.

9. The method of claim 5 wherein said alarm response initiates execution of a program.

10. The method of claim 5 wherein said alarm response initiates a message to a network.

11. The method of claim 10 wherein said alarm response is an SNA alert message.

12. The method of claim 5 wherein said alarm response is an SNMP trap message.

13. The method of claim 5 wherein said alarm response is an exception message.

14. The method of claim 5 wherein said alarm response invokes a list of statistics which trigger an alarm.

15. The method of claim 14 wherein invoking said alarm response comprises the step of invoking a list of corrective actions which may be taken.

16. The method of claim 5 wherein said alarm response is generated when said new statistic is greater than a threshold value.

17. The method of claim 5 wherein said alarm response is generated when said new statistic is less than a threshold value.

18. The method of claim 4 wherein said alarm condition invokes a plurality of alarm responses.

19. The method of claim 18 wherein said step invoking a plurality of alarm responses comprises the step of invoking a list of statistics which trigger an alarm and a list of corrective actions which may be taken.

20. A computer-implemented method for performance tuning a component of a computer system, the computer system having at least the component, a processor, display, and user controls, comprising the steps of:

dynamically receiving during operation of the computer system at least one expression defining at least one new statistic, said expression containing at least one performance statistic of said component and a mathematical operator;

reading, by said processor, said performance statistic contained in said expression;

filtering, by said processor, said performance statistic to generate said new statistic;

testing said generated new statistic;

in response to said testing step, adjusting said component for optimal performance; and

in response to said testing step, dynamically receiving during operation of said computer system a second expression defining at least one new second statistic, said second expression comprising at least said new statistic and a second mathematical operator.

21. The method of claim 20 further comprising the step of:

adding said new statistic to said performance statistic for use by said system.

22. A computer system for dynamically defining new statistics from existing performance statistics of at least one context class of the computer system to monitor performance thereon, comprising:

user controls for dynamically receiving during operation of said computer system at least one expression defining at least one new statistic, said expression comprising at least one mathematical operator and at least one of said existing performance statistics;

means for reading said at least long existing performance statistic contained in said expression from memory;

means for filtering said at least one existing performance statistic to generate said new statistic;

means for adding said new statistic to said set of existing performance statistics in said memory so that at least one program running on said computer system can utilize said new statistic, wherein said new statistic becomes one of said set of existing performance statistics; and

(e) said user controls for dynamically receiving a second expression defining a second new statistic, said second expression comprising at least said new statistic and a second mathematical operator.

23. The system of claim 22 wherein said means for filtering comprises means for performing boolean and arithmetic operations on said existing performance statistic.

24. The system of claim 22 wherein said exiting performance statistics comprise statistics from local and remote data processing systems.

25. The system according to claim 22 further comprising:

means for testing said new statistic; and

means for generating at least one alarm condition in response to testing said new statistic.

26. The system of claim 25 wherein said means for generating said alarm condition comprises means for invoking a plurality of alarm responses.

27. The system of claim 26 wherein said plurality of alarm responses comprise means for invoking a list of statistics that trigger an alarm and a list of corrective actions that may be taken.
