Abstract

A method and a computer program product for measuring and monitoring performance in a computer network environment that includes multiple clients and one or more servers providing one or more services is disclosed. The method includes monitoring the performance at each client based on true requests send to the servers over a network connection. The performance at each client is collected at a performance monitor database, where the collected performance data can be extracted to yield the performance of e.g. specific servers or services towards a specific client or a group of clients or the performance of a connection between a server and a client. The system performance is thereby measured at the clients where the system performance is actually utilized. The present invention thereby provides a more realistic scenario of the actual system performance than prior art systems based on monitoring server performance at the servers or through simulated clients.

Claims

1. A method for measuring and monitoring performance in a computer network environment, the computer network environment being comprised of multiple clients and one or more servers providing one or more services, the method comprising:

monitoring at each client at least a first performance parameter representing the interaction between the client and a server for each true request sent to the server, the performance parameter comprising information about which type of service the request was related to and to which server it was sent;

repetitively collecting data representing the monitored performance parameters from each client at the performance monitor database, and

combining performance parameters for one or more of;

requests sent to a specific server, requests related to a specific service type, and requests sent from a specific group of clients;

thereby extracting, from the data monitored at the clients, performance parameters for at least one of;

one or more servers;

one or more services; and

a connection between a server and a client;

whereby the database contains data representative of the at least first performance parameter over time.

2. A method according to claim 1 further comprising monitoring at each client a client performance parameter of the operational system of the client.

3. A method according to claim 1 further comprising the monitoring at each client a performance parameter for the interaction between the client and a server for each true request to a server, the performance parameter being related to the performance of the server in response to true requests from the client.

4. A method according to claim 1, wherein the at least first performance parameter represents a response time of a server upon a request from a client.

5. A method according to claim 1, wherein the collection of data is performed by at least one agent comprised in one or more of the clients.

6. A method according to claim 5, wherein the collection of data is performed passively by the at least one agent.

7. A method according to claim 5, wherein the at least one agent is distributed to each client.

8. A method according to claim 7, wherein the at least one agent is automatically installed.

9. A method according to claim 8, wherein the at least one agent begins collection of data substantially immediately after installation.

10. A method according to claim 4, wherein the response time is the time interval starting when the request, to the server, has been sent from the client until the response from the server arrives at the client.

11. A method according to claim 1, wherein the at least first performance parameter is selected from the set of:

CPU usage, memory usage, thread count for a process, handle count for a process, number of transferred bytes, number of made connections, number of transmissions and/or number of package trains send/received.

12. A method according to claim 11, wherein the memory usage comprises free physical memory, virtual memory or a free paging file.

13. A method according to claim 1, wherein the data in the database is organised in data sets so that each set of data represents at least one specific group of clients.

14. A method according to claim 13, wherein the at least one specific group corresponds to at least one of the servers.

15. A method according to claim 1, wherein the data representing the at least first performance parameter is represented by consolidated data, which is accumulated into one or more predetermined performance parameter intervals and stored in the database.

16. A method according to claim 1, wherein the data representing the at least first performance parameter is represented by consolidated data, which is accumulated into one or more predetermined time intervals and stored in the database.

17. A method according to claim 16, wherein the consolidated data represents the performance of a server, in relation to at least one client.

18. A method according to claim 1, wherein the computer network environment comprises at least one administrator device.

19. A method according to claim 1, wherein the clients form a part of a front end system.

20. A method according to claim 19, wherein the front end system comprises at least one administrator device.

21. A method according to claim 1, wherein at least one of the one or more servers form a part of a back end system.

22. A method according to claim 21, wherein the back end system comprises the database.

23. A method according to claim 1, wherein the database comprises a relational database.

24. A method according to claim 1, wherein the data are presented in an administrator display.

25. A method according to claim 24, wherein the administrator display comprises a graphical interface.

26. A method according to claim 24, wherein the administrator display is accessible through any electronic device having a display.

27. A method according to claim 25, wherein the administrator display is accessible through an Internet web browser.

28. A method of performing error detection in a computer network environment, the method comprising using data representative of at least a first performance parameter, the data being provided to a database using a method according to claim 1, for providing information of the at least first performance parameter to an administrator of the computer network environment for error detection/tracing.

29. A method according to claim 28, wherein the error detection is performed on component level.

30. A method according to claim 29, wherein the component comprises CPU, RAM, hard disks, drivers, network devices, storage controllers and storage devices.

31. A method according to claim 1, wherein the computer network is at least partly a wireless network.

32. A method according to claim 1, wherein the computer network is partly a wireless network and partly a wired network.

33. A system for measuring and monitoring performance in a computer network environment, the computer network environment being comprised of comprising multiple clients and one or more servers providing one or more services, the system comprising:

an agent for collecting, during a predetermined period of time, data representative of at least a first performance parameter, said first performance parameter being related to the performance of the one or more servers in response to true requests from at least one client, and

a database for storing the collected data;

wherein the agent repetitively collects data and provide the data to the database, whereby the database contains data representative of the at least first performance parameter over time.

34. A computer program product for measuring and monitoring performance in a computer network environment, the computer network environment being comprised of multiple clients and one or more servers providing one or more services, the computer program product comprising:

monitoring at each client at least a first performance parameter for the interaction between the client and a server for each true request to a server, this performance parameter comprising information of which type of service the request was related to and to which server it was sent,

means for providing a performance monitor database connected to the network,

means for repetitively collecting data representing the monitored performance parameters from each client at the performance monitor database, and

means for combining performance parameters for requests to a specific server and/or requests related to a specific service type; and

at least one of requests from a specific group of clients,

whereby the database contains data representative of the at least first performance parameter over time.

35. A computer-readable data carrier loaded with a computer program product according to claim 34.
