Abstract

Described herein are a method and a tool for performance measurement of a business scenario step in an enterprise environment, which support “per business scenario step” granularity and do not attach any agents to the enterprise environment, thus avoiding any memory or CPU time overheads. The performance measurements are based on two sets of system readings collected prior to the and after the execution of the business scenario step. The method calculates the memory used by the enterprise environment during the business scenario step execution, the elapsed CPU times used by all Operation System (OS) processes involved, the number and duration of all roundtrips between the Hyper Text Transfer Protocol (HTTP) browser initiating the execution of the business scenario step and the enterprise environment, and between the enterprise environment and all back-ends involved.

Claims

1. A method for performance measurement of a business scenario step in an enterprise environment, comprising:

identifying a business scenario step;

collecting a first set of system readings prior to execution of the business scenario step;

collecting a second set of system readings after the execution of the business scenario step;

measuring the business scenario step performance using the first and the second set of system readings; and

displaying measurement results.

2. The method of claim 1, wherein identifying a business scenario step comprises acquiring a name of the business scenario step from a predefined list of business scenario steps.

3. The method of claim 1, wherein collecting the first set of system readings comprises:

receiving a first memory usage of the enterprise environment;

receiving a first set of elapsed CPU times of all processes involved in the enterprise environment;

acquiring a garbage collection log pointer to the end of garbage collection log files of the enterprise environment;

acquiring a back-end usage log pointer to the end of back-end usage log files of the enterprise environment; and

acquiring a HTTP session log pointer to the end of HTTP session log files of the enterprise environment.

4. The method of claim 3, wherein collecting the second set of system readings comprises:

receiving a second memory usage of the enterprise environment;

receiving a second set of elapsed CPU times of all processes involved in the enterprise environment;

collecting garbage collection logs from the garbage collection log pointer to the end of the garbage collection log files of the enterprise environment;

collecting back-end usage logs from the back-end usage log pointer to the end of the back-end usage log files of the enterprise environment; and

collecting HTTP session logs from the HTTP session log pointer to the end of the HTTP session log files of the enterprise environment.

5. The method of claim 1, wherein measuring the business scenario step performance comprises:

calculating an amount of memory used by the enterprise environment during the business scenario step execution;

calculating an amount of elapsed CPU times used by all processes involved in the enterprise environment during the business scenario step execution;

calculating a number and duration of all roundtrips between the enterprise environment and all back-ends involved in the business scenario step execution; and

calculating a number and duration of all roundtrips between an HTTP browser, used to trigger the business scenario step execution, and the enterprise environment.

6. A tool for performance measurement of a business scenario step in an enterprise environment, comprising:

a business scenario step reader to identify a business scenario step;

a data collector to collect a first set of system readings prior to the business scenario step execution and a second set of system readings after the business scenario step is executed;

a data analyzer to measure the business scenario step performance using the first and the second set of system readings; and

a report generator to generate user readable reports from the measurements performed by the data analyzer.

7. The tool of claim 6, wherein the business scenario step reader comprises an interface to acquire a name of the business scenario step from a predefined list of business scenario steps.

8. The tool of claim 6, wherein the first set of system readings comprises:

a first memory usage of the enterprise environment;

a first set of elapsed CPU times of all processes involved in the enterprise environment;

a garbage collection log pointer to the end of garbage collection log files of the enterprise environment;

a back-end usage log pointer to the end of back-end usage log files of the enterprise environment; and

a HTTP session log pointer to the end of HTTP session log files of the enterprise environment.

9. The tool of claim 8, wherein the second set of system readings comprises:

a second memory usage of the enterprise environment;

a second set of elapsed CPU times of all processes involved in the enterprise environment;

garbage collection logs from the garbage collection log pointer to the end of the garbage collection log files of the enterprise environment;

back-end usage logs from the back-end usage log pointer to the end of the back-end usage log files of the enterprise environment; and

HTTP session logs from the HTTP session log pointer to the end of the HTTP session log files of the enterprise environment.

10. The tool of claim 6, wherein the data analyzer measurements comprise:

a calculation of an amount of memory used by the enterprise environment during the business scenario step execution;

a calculation of an amount of elapsed CPU times used by all processes involved in the enterprise environment during the business scenario step execution;

a calculation of a number and duration of all roundtrips between the enterprise environment and all back-ends involved in the business scenario step execution; and

a calculation of a number and duration of all roundtrips between an HTTP browser, used to trigger the business scenario step execution, and the enterprise environment.

11. A machine readable medium having a set of instruction stored therein which when executed cause a machine to perform a set of operations measuring the performance of a business scenario step in an enterprise environment, comprising:

identifying a business scenario step;

collecting a first set of system readings prior to execution of the business scenario step;

collecting a second set of system readings after the execution of the business scenario step;

measuring the business scenario step performance using the first and the second set of system readings; and

displaying measurement results.

12. The machine readable medium of claim 11, having a set of instruction stored therein which when executed cause a machine to perform a set of operations, wherein identifying a business scenario step comprises acquiring a name of the business scenario step from a predefined list of business scenario steps.

13. The machine readable medium of claim 11, having a set of instruction stored therein which when executed cause a machine to perform a set of operations, wherein collecting the first set of system readings comprises:

receiving a first memory usage of the enterprise environment;

receiving a first set of elapsed CPU times of all processes involved in the enterprise environment;

acquiring a garbage collection log pointer to the end of garbage collection log files of the enterprise environment;

acquiring a back-end usage log pointer to the end of back-end usage log files of the enterprise environment; and

acquiring a HTTP session log pointer to the end of HTTP session log files of the enterprise environment.

14. The machine readable medium of claim 13, having a set of instruction stored therein which when executed cause a machine to perform a set of operations, wherein collecting the second set of system readings comprises:

receiving a second memory usage of the enterprise environment;

receiving a second set of elapsed CPU times of all processes involved in the enterprise environment;

collecting garbage collection logs from the garbage collection log pointer to the end of the garbage collection log files of the enterprise environment;

collecting back-end usage logs from the back-end usage log pointer to the end of the back-end usage log files of the enterprise environment; and

collecting HTTP session logs from the HTTP session log pointer to the end of the HTTP session log files of the enterprise environment.
