Abstract

One preferred embodiment of the present invention provides systems and methods for analyzing the delivery performance of newsgroup services. Briefly described, in architecture, one embodiment, among others, includes a newsgroup evaluation system configured to determine a delivery rate for a newsgroup server. In other embodiments, methods and systems are provided for analyzing completion and retention for newsgroup services.

Claims

1. A method for assessing delivery performance of a network server over a communication network, comprising:

making a request for a service to be performed by the network server;

measuring a delivery rate at which the service is performed by the network server;

comparing a measurement of the delivery rate with the nominal standard for performing the service successfully;

checking operability of the communication network to determine feasibility in making an independent assessment of a performance of the network server with regard to the communication network, wherein a determination is made as to whether the communication network is currently supporting a delivery rate for the network server above a nominal standard;

saving results of the comparison if the independent assessment is determined to be possible; and

disregarding the results of the comparison if the independent assessment is determined to not be possible.

2. The method of claim 1, further comprising:

receiving a request to perform the independent assessment of the network server.

3. The method of claim 1, further comprising:

determining the delivery rate of the network server, the delivery rate comprising a rate at which the network server delivers a requested data file to a client; and

displaying the delivery rate.

4. The method of claim 1, wherein checking operability of the communication network comprises pinging the network server to obtain a ping result which is used as a basis for making the independent assessment determination.

5. The method of claim 4, further comprising:

storing the delivery rate; and

storing the ping result.

6. The method of claim 3, wherein:

the independent assessment of the network server is performed according to evaluation parameters, the evaluation parameters including a nominal speed; and

a delivery grade is assessed to the delivery rate based on the nominal speed.

7. The method of claim 6, the displaying of the delivery rate comprising:

creating an entry in a database;

storing the delivery rate in the entry;

storing the ping result in the entry; and

storing the delivery grade in the entry.

8. The method of claim 6, further comprising:

storing the delivery rate; and

storing the delivery grade.

9. The method of claim 6, the displaying of the delivery rate further comprising:

plotting the delivery rate on a graph;

shading a plot on the graph a particular color for a particular delivery grade of the plot; and

displaying the graph.

10. The method of claim 6, wherein the evaluation parameters include a list of notification addresses to contact for a delivery grade that is a FAILURE, the method further comprising:

after determining that the delivery grade is a FAILURE, sending a notification message to each notification address.

11. The method of claim 10, wherein at least one of the notification addresses is an email address.

12. The method of claim 10, wherein at least one of the notification addresses is a telephone number.

13. The method of claim 10, wherein at least one of the notification addresses is an instant messaging address.

14. The method of claim 6, wherein the evaluation parameters include a list of notification addresses to contact for a delivery grade that is a FAILURE and a minimum failure count, the method further comprising:

after performing a series of evaluation tasks, tracking a number of delivery grades that are a FAILURE; and

after determining the number of the delivery grades that are a FAILURE for the series, sending a notification message to each notification address if the number is equal to or more than the minimum failure count, wherein the minimum failure count is specified by a user.

15. The method of claim 14, wherein at least one of the notification addresses is an email address.

16. The method of claim 14, wherein at least one of the notification addresses is a telephone number.

17. The method of claim 14, wherein in at least one of the notification addresses is an instant messaging address.

18. The method of claim 2, further comprising:

configuring a scheduling time for performing the independent assessment of the network server.

19. The method of claim 18, further comprising:

automatically generating a request for performing the independent assessment of the network server in conformance with the scheduling time.

29. The method of claim 1, wherein the network server is a newsgroup server and the service comprises retrieval and delivery of a newsgroup article.

30. The method of claim 1, wherein a determination is further made as to whether an external network hosting the network server is currently supporting a delivery rate for the network server above the nominal standard.

20. A computer-readable storage medium having a program for assessing delivery performance of a network server over a communication network, the storage medium excluding signals, the program having instructions for performing:

making a request for a service to be performed by the network server;

measuring a delivery rate at which the service is performed by the network server;

comparing a measurement of the delivery rate with the nominal standard for performing the service successfully;

checking operability of the communication network to determine feasibility in making an independent assessment of a performance of the network server with regard to the communication network, wherein a determination is made as to whether the communication network is currently supporting a delivery rate for the network server above a nominal standard;

saving results of the comparison if the independent assessment is determined to be possible; and

disregarding the results of the comparison if the independent assessment is determined to not be possible.

21. The medium of claim 20, the program further performing:

receiving a request to perform the independent assessment of the network server.

22. The medium of claim 21, further comprising:

automatically generating a request for performing the independent assessment of the network server in conformance with a scheduling time specified by a user.

23. The medium of claim 20, further comprising:

determining the delivery rate of the network server, the delivery rate comprising a rate at which the network server delivers a requested data file to a client; and

displaying the delivery rate.

24. The medium of claim 23, wherein:

the independent assessment of the network server is performed according to evaluation parameters, the evaluation parameters including a nominal speed; and

a delivery grade is assessed to the delivery rate based on the nominal speed.

25. The medium of claim 24, the displaying of the delivery rate further comprising:

plotting the delivery rate on a graph;

shading a plot on the graph a particular color for a particular delivery grade of the plot; and

displaying the graph.

26. The medium of claim 24, wherein the evaluation parameters include a list of notification addresses to contact for a delivery grade that is a FAILURE, the method further comprising:

after determining that the delivery grade is a FAILURE, sending a notification message to each notification address.

27. The medium of claim 24, wherein the evaluation parameters include a list of notification addresses to contact for a delivery grade that is a FAILURE and a minimum failure count, the method further comprising:

after performing a series of evaluation tasks, tracking a number of delivery grades that are a FAILURE; and

after determining the number of the delivery grades that are a FAILURE for the series, sending a notification message to each notification address if the number is equal to or more than the minimum failure count, wherein the minimum failure count is specified by a user.

28. The medium of claim 20, wherein the network server is a newsgroup server and the service comprises retrieval and delivery of a newsgroup article.
