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 Lightweight Directory Access Protocol (LDAP) server environment, comprising:

parsing, via a computer processor, an audit log of a server in the server environment, wherein the audit log contains operations that have been processed by the server and wherein the parsing removes all extraneous information from the audit log, leaving only the actual operations that were processed by the server;

simulating a multi-user load having concurrent thread activity that the server has previously experienced by feeding an entirety of the operations in the parsed audit log and bind requests generated for the operations to the server and executing the entirety of the operations by the server, wherein concurrent thread activity is simulated by feeding each of the bind requests and each of the operations in the parsed audit log to the server with a separate thread; and

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

2. 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.

3. 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.

4. 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.

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

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

7. The method of claim 1, further comprising performing capacity planning using the generated statistics.

8. A system for simulating activity in a Lightweight Directory Access Protocol (LDAP) server environment, comprising:

at least one computer processor that performs a method, comprising;

parsing an audit log of a server in the server environment, wherein the audit log contains operations that have been processed by the server and wherein the parsing removes all extraneous information from the audit log, leaving only the actual operations that were processed by the server;

generating bind requests for the operations and simulating a multi-user load having concurrent thread activity that the server has previously experienced by feeding an entirety of the operations in the parsed audit log and the associated bind requests to the server and executing the entirety of the operations by the server, wherein concurrent thread activity is simulated by feeding each of the bind requests and each of the operations in the parsed audit log to the server with a separate thread; and

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

9. The system of claim 8, wherein the method further comprises making a request to the server environment with a separate thread for each of the operations contained in the parsed audit log.

10. The system of claim 8, wherein the method further comprises retrieving a set of audit logs from the server environment after the feeding step, and generates the statistics based on the set of audit logs.

11. The system of claim 8, 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.

12. The system of claim 8, wherein the server environment comprises at least one server.

13. A computer readable storage device having a program product stored thereon for simulating activity in a Lightweight Directory Access Protocol (LDAP) server environment, which when executed, performs a method, comprising:

parsing an audit log of a server in the server environment, wherein the audit log contains operations that have been processed by the server and wherein the parsing removes all extraneous information from the audit log, leaving only the actual operations that were processed by the server;

simulating a multi-user load having concurrent thread activity that the server has previously experienced by feeding an entirety of the operations in the parsed audit log and bind requests generated for the operations to the server and executing the entirety of the operations by the server, wherein concurrent thread activity is simulated by feeding each of the bind requests and each of the operations in the parsed audit log to the server with a separate thread; and

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

14. The program product of claim 13, wherein feeding makes a request to the server environment with a separate thread for each of the operations contained in the parsed audit log.

15. The program product of claim 13, wherein the 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.

16. The program product of claim 13, 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.

17. The program product of claim 13, wherein the server environment comprises at least one server.
