Abstract

A performance monitoring system uses a client/server architecture across a network including a plurality of interconnected computers. A data collector process collects and stores data from a monitored process, wherein the data collector process allows a user to control a frequency of collection for each of one or more different types of the collected data and gathers the different types of the collected data in parallel from the monitored process. A server process distributes the data collected by the data collector process to one or more client processes. Each client process manages a connection with the server process on behalf of one or more performance monitoring applications and relays data requests to the server process and delivers results therefrom to the performance monitoring applications.

Claims

1. A system for gathering and distributing performance and utilization data, comprising:

a network including a plurality of interconnected computers;

a data collector process executed by a computer for collecting data from a monitored process and for storing the collected data, wherein the data collector process allows a user to control a frequency of collection for each of one or more different data types of the collected data and gathers the different types of the collected data in parallel from the monitored process;

a server process executed by a computer for distributing the data collected by the data collector process; and

one or more client processes executed by one or more computers for receiving the distributed data from the server process across the network, wherein the client process manages a connection with the server process on behalf of one or more performance monitoring applications and relays data requests to the server process and delivers results therefrom to the performance monitoring applications.

2. The system of claim 1 above, further comprising a dynamic link library (DLL) executed by a computer for exposing a set of data types and functions that can be invoked by the data collector process to collect the data.

3. The system of claim 1 above, wherein a table stores information about the server processes.

4. The system of claim 3 above, wherein the table contains one row for each active server process.

5. The system of claim 4 above, wherein the data collector process inserts a row into the table when a server process is started and deletes the row when the server process is terminated.

6. The system of claim 3 above, wherein the client process accesses the table in order to connect to the server process.

7. The system of claim 3 above, wherein the table includes one or more data items selected from a group comprising:

an address of the computer executing the server process;

a name of the computer executing the server process;

an active profile for the data collector process;

a user that is logged onto the monitored process;

a name of the monitored process;

a date and time the data collector process started;

one or more identifiers representing the types of data that are currently being collected;

a number of client processes currently connected to the server process;

a maximum number of client processes allowed to connect to the server process; and

a network port number used in the server process.

8. The system of claim 1 above, wherein the server process transmits only specified data collected by the data collector process to the client process.

9. A system for gathering and distributing performance and utilization data, comprising:

a network including a plurality of interconnected computers;

a data collector process executed by a computer for providing access to a monitored process through which any data of interest may be collected;

a server process executed by a computer for distributing the collected data;

one or more client processes executed by one or more computers for receiving the distributed data from the server process across the network; and

one or more application processes executed by one or more computers for sending requests to and receiving data from the client process.

10. The system of claim 9 above, further comprising a dynamic link library (DLL) executed by a computer for exposing a set of data types and functions that can be invoked by the data collector process to collect the data.

11. The system of claim 9 above, wherein a table stores information about the server processes.

12. The system of claim 11 above, wherein the table contains one row for each active server process.

13. The system of claim 12 above, wherein the data collector process inserts a row into the table when a server process is started and deletes the row when the server process is terminated.

14. The system of claim 11 above, wherein the client process accesses the table.

15. The system of claim 11 above, wherein the table includes one or more data items selected from a group comprising:

an address of the computer executing the server process;

a name of the computer executing the server process;

an active profile for the data collector process;

a user that is logged onto the monitored process;

a name of the monitored process;

a date and time the data collector process started;

one or more identifiers representing the types of data that are currently being collected;

a number of clients processes currently connected to the server process;

a maximum number of client processes allowed to connect to the server process; and

a network port number used in the server process.

16. The system of claim 9 above, wherein the data collector process caches the collected data.

17. The system of claim 9 above, wherein the data collector process includes means for allowing a user to control a frequency of collection for each of one or more different types of collected data.

18. The system of claim 17 above, wherein the data collector process includes means for gathering the different types of data in parallel from the monitored process.

19. The system of claim 9 above, wherein the server process responds to requests from client process by transmitting data collected by the data collector process to the client process.

20. The system of claim 19 above, wherein the server process transmits only specified data collected by the data collector process to the client process.

21. The system of claim 9 above, wherein the client process manages a connection with a remote server process on behalf of local performance monitoring application.

22. The system of claim 9 above, wherein the client process relays data requests to the server process and delivers results therefrom to a requesting application.

23. A method of gathering and distributing performance and utilization data, comprising the steps of:

collecting data from a monitored process;

distributing the collected data from a server to one or more client processes executed by one or more computers, wherein the client processes manages a connection with the server process on behalf of a local performance monitoring application and relays data requests to the server process and delivers results therefrom to the application.
