Abstract

The present invention provides a method of estimating computing system resource usage by the process of obtaining raw utilisation data from a computing system and applying a mathematical model to the input data, thereby providing an estimate of resource usage for a individual transaction type within the computing environment.

Claims

1. A method of estimating computing system resource usage of each individual transaction type in a computing system arranged to process a plurality of transaction types within a given time interval, comprising the steps of, obtaining a plurality of samples of raw utilisation data of a system resource and a corresponding plurality of samples of transaction count data for a plurality of transaction types, and applying a mathematical model to the data to provide an estimate of the resource usage for each individual transaction type of the multiple transaction types within the computing environment.

2. A method in accordance with claim 1, wherein the method comprises the further preliminary step of determining the minimum set of characteristics required to provide said estimate.

3. A method in accordance with claim 1, wherein the said mathematical model is a linear least squares algorithm.

4. A method in accordance with claim 1, comprising the further step of estimating error values for the estimates of the said resource usage for an individual transaction type within the computing environment.

5. A method in accordance with claim 1, wherein the said system resource is the processing time of the CPU.

6. A method in accordance with claim 1, wherein the said system resource is a storage device access time.

7. A method in accordance with claim 1, wherein the said system resource is the number of I/O completions minus the number of interrupts.

8. A method in accordance with claim 1, wherein the said system resource is the number of system interrupts.

9. A method in accordance with claim 1, wherein the said system resource is the number of network packets.

10. A method in accordance with claim 1, wherein the said system resource is a system memory cache.

11. A method in accordance with claim 1, wherein the said system resource is a software sub-system resource.

12. A method in accordance with claim 1, wherein the said system resource is a function within a software sub-system.

13. A method in accordance with claim 1, wherein the said system resource is a software package.

15. A computer program arranged when loaded on a computing system to perform the method of claim 1.

16. A computer readable medium providing a computer program in accordance with claim 15.

14. A computing system arranged to facilitate the estimation of resource usage of each individual transaction type within a computer environment arranged to process a plurality of transaction types, comprising a data gathering means arranged to gather raw utilisation data of a computer resource and transaction count data, a processing means arranged to apply a mathematical model to the raw input data to produce a set of output data, whereby the output data provides an estimate of resource usage of the each individual transaction type within the computing environment.
