Abstract

Under the present invention an audit log for the server environment is obtained and parsed to remove any extraneous information. The parsing operation will typically leave only the previous operations processed by the server environment in the audit log. Thereafter, the parsed audit log is fed back to the server environment. Specifically, each operation in the audit log is fed back to the server environment as a request. Each request will typically have its own thread to simulate concurrent thread activity in the server environment. After the requests have been fed, statistics corresponding to the resulting performance of the server environment will be generated.

Claims

1. A method for simulating activity in a server environment, comprising:

parsing an audit log of the server environment, wherein the audit log contains operations that have been processed by the server environment;

feeding the operations in the parsed audit log to the server environment, wherein each of the operations in the parsed audit log is fed to the server environment with a separate thread to simulate concurrent thread activity; and

generating statistics for the server environment in response to the feeding.

2. The method of claim 1, wherein the server environment is a Lightweight Directory Access Protocol (LDAP) environment.

3. The method of claim 1, wherein the feeding step comprises making a request to the server environment with a separate thread for each of the operations contained in the parsed audit log.

4. The method of claim 1, wherein the operations are Lightweight Directory Access Protocol (LDAP) operations.

5. The method of claim 1, wherein the generating step comprises:

retrieving a set of audit logs from the server environment after the feeding step; and

generating the statistics based on the set of audit logs.

6. The method of claim 1, wherein the statistics comprise at least one statistic selected from the group consisting of a number of operations by Internet Protocol address, a number of operations per hour, response times, a number of search operations, a number of modification operations, a number of addition operations, a number of delete operations and a filter analysis.

7. The method of claim 1, wherein the server environment comprises a plurality of servers.

8. The method of claim 1, wherein the server environment comprises a single server.

9. A method for simulating activity in a Lightweight Directory Access Protocol (LDAP) environment, comprising:

parsing an audit log of the LDAP environment, wherein the audit log contains operations that have been processed by the LDAP environment;

feeding the operations in the parsed audit log to the LDAP environment as requests, wherein each of the requests are fed to the LDAP environment with a separate thread to simulate concurrent thread activity; and

generating statistics for the LDAP environment in response to the feeding.

10. A system for simulating activity in a server environment, comprising:

a log scrubber for parsing an audit log of the server environment, wherein the audit log contains operations that have been processed by the server environment;

an exploiter simulator for feeding the operations in the parsed audit log to the server environment, wherein each of the operations in the parsed audit log is fed to the server environment with a separate thread to simulate concurrent thread activity; and

a log analyzer for generating statistics for the server environment in response to the feeding.

11. The system of claim 10, wherein the server environment is a Lightweight Directory Access Protocol (LDAP) environment.

12. The system of claim 10, wherein the exploiter simulator makes a request to the server environment with a separate thread for each of the operations contained in the parsed audit log.

13. The system of claim 10, wherein the operations are Lightweight Directory Access Protocol (LDAP) operations.

14. The system of claim 10, wherein the log analyzer retrieves a set of audit logs from the server environment after the feeding step, and generates the statistics based on the set of audit logs.

15. The system of claim 10, wherein the statistics comprise at least one statistic selected from the group consisting of a number of operations by Internet Protocol address, a number of operations per hour, response times, a number of search operations, a number of modification operations, a number of addition operations, a number of delete operations and a filter analysis.

16. The system of claim 10, wherein the server environment comprises at least one server.

17. A program product stored on a recordable medium for simulating activity in a server environment, which when executed, comprises:

program code for parsing an audit log of the server environment, wherein the audit log contains operations that have been processed by the server environment;

program code for feeding the operations in the parsed audit log to the server environment, wherein each of the operations in the parsed audit log is fed to the server environment with a separate thread to simulate concurrent thread activity; and

program code for generating statistics for the server environment in response to the feeding.

18. The program product of claim 17, wherein the server environment is a Lightweight Directory Access Protocol (LDAP) environment.

19. The program product of claim 17, wherein the program code for feeding makes a request to the server environment with a separate thread for each of the operations contained in the parsed audit log.

20. The program product of claim 17, wherein the operations are Lightweight Directory Access Protocol (LDAP) operations.

21. The program product of claim 17, wherein the program code for generating retrieves a set of audit logs from the server environment after the feeding step, and generates the statistics based on the set of audit logs.

22. The program product of claim 17, wherein the statistics comprise at least one statistic selected from the group consisting of a number of operations by Internet Protocol address, a number of operations per hour, response times, a number of search operations, a number of modification operations, a number of addition operations, a number of delete operations and a filter analysis.

23. The program product of claim 17, wherein the server environment comprises at least one server.

24. A system for deploying an application for simulating activity in a server environment, comprising:

a computer infrastructure being operable to;

parse an audit log of the server environment, wherein the audit log contains operations that have been processed by the server environment;

feed the operations in the parsed audit log to the server environment, wherein each of the operations in the parsed audit log is fed to the server environment with a separate thread to simulate concurrent thread activity; and

generate statistics for the server environment in response to the feeding.

25. Computer software embodied in a propagated signal for simulating activity in a server environment, the computer software comprising instructions to cause a computer system to perform the following functions:

parse an audit log of the server environment, wherein the audit log contains operations that have been processed by the server environment;

feed the operations in the parsed audit log to the server environment, wherein each of the operations in the parsed audit log is fed to the server environment with a separate thread to simulate concurrent thread activity; and

generate statistics for the server environment in response to the feeding.
