Abstract

A device monitors a system'"'"'s available resources and produces either a deferred notification or an instant notification based on a comparison with an established threshold. The threshold may be adjusted if current or anticipated system resource utilization changes. Changes to the threshold may result in deferred notifications being removed from a queue and an instant notification being transmitted to a reporting facility.

Claims

1. An adaptive message-delivery system, comprising:

a system-resource monitoring device adapted to monitor a plurality of system resources of a first type in a system under test and generate a first resource number indicative of a quantity of said first type of system resources that is currently available; and

a threshold-establishment device adapted to receive said first resource number and compare it with a first threshold number indicative of a minimum acceptable number of said plurality of system resources of a first type and, if the first resource number is less than the first threshold number, to transmit a first instant notification or, if the first resource number is equal to or greater than the first threshold number, to place a first deferred notification in a notification queue.

2. The adaptive message-delivery system of claim 1, further comprising a predictive device adapted to anticipate a future utilization of said plurality of system resources and to adjust said first threshold number based on said future utilization of said plurality of system resources.

3. The adaptive message-delivery system of claim 2, wherein the predictive device is further adapted to maintain a history of utilization of said plurality of system resources of a first type.

4. The adaptive message-delivery system of claim 3, wherein said future utilization is based on said history of utilization.

5. The adaptive message-delivery system of claim 2, wherein the notification queue is adapted to remove the deferred notification from the notification queue and to transmit a second instant notification, if the first resource number is less than the first threshold number adjusted by the predictive device.

6. The adaptive message-delivery system of claim 1, wherein said threshold-establishment device 16 is adapted to transmit said first instant notification to a reporting facility.

7. A method of adaptively delivering messages, comprising the steps of:

establishing a threshold number indicative of a minimum acceptable number of a plurality of system resources of a first type;

establishing a resource number indicative of a quantity of the plurality of system resources of a first type that is currently available;

comparing the threshold number to the resource number; and

if the resource number is less than the threshold number, transmitting a first instant notification.

8. The method of claim 7, further comprising the step of placing a deferred notification in a notification queue, if the resource number is equal to or greater than the threshold number.

9. The method of claim 7, further comprising the step of:

anticipating a future utilization of said plurality of system resources of a first type.

10. The method of claim 9, further comprising the step of:

adjusting said first threshold number based on said anticipating a future utilization of said plurality of system resources of a first type.

11. The method of claim 7, further comprising the step of:

maintaining a history of utilization of said plurality of system resources of a first type.

12. The method of claim 11, further comprising the step of:

anticipating a future utilization of said plurality of system resources of a first type based on said maintaining a history of utilization of said plurality of system resources of a first type.

13. The method of claim 12, further comprising the step of:

adjusting said first threshold number based on said anticipating a future utilization of said plurality of system resources of a first type.

14. The method of claim 7, further comprising the steps of:

placing a deferred notification in a notification queue;

maintaining a historical utilization of said plurality of system resources of a first type;

anticipating a future utilization of said plurality of system resources of a first type based on said maintaining a history of utilization of said plurality of system resources of a first type;

adjusting said first threshold number based on said anticipating a future utilization of said plurality of system resources of a first type;

removing the deferred notification from the notification queue; and

transmitting a second instant notification.

15. An article of manufacture including a data storage medium, said data storage medium including a set of machine-readable instructions that are executable by a processing device to implement an algorithm, said algorithm comprising the steps of:

establishing a threshold number indicative of a minimum acceptable number of a plurality of system resources of a first type;

establishing a resource number indicative of a quantity of the plurality of system resources of a first type that is currently available;

comparing the threshold number to the resource number; and

if the resource number is less than the threshold number, transmitting a first instant notification.

16. The article of manufacture of claim 15, further comprising the step of placing a deferred notification in a notification queue, if the resource number is equal to or greater than the threshold number.

17. The article of manufacture of claim 15, further comprising the step of:

maintaining a history of utilization of said plurality of system resources of a first type.

18. The article of manufacture of claim 17, further comprising the step of:

anticipating a future utilization of said plurality of system resources of a first type based on said maintaining a history of utilization of said plurality of system resources of a first type.

19. The article of manufacture of claim 18, further comprising the step of:

adjusting said first threshold number based on said anticipating a future utilization of said plurality of system resources of a first type.

20. The article of manufacture of claim 19, further comprising the steps of:

placing a deferred notification in a notification queue;

maintaining a historical utilization of said plurality of system resources of a first type;

anticipating a future utilization of said plurality of system resources of a first type based on said maintaining a history of utilization of said plurality of system resources of a first type;

adjusting said first threshold number based on said anticipating a future utilization of said plurality of system resources of a first type;

removing the deferred notification from the notification queue; and

transmitting a second instant notification.
