Systems and methods for providing for degradation of a computer application
View Patent ↗A method for providing for the graceful degradation of the performance and functionality of a distributed computer application. A plurality of sensors monitor the performance and availability of various external resources and/or services required by the application, as well as the performance of various components of the application, and report the information to one or more controllers. The controllers make decisions based on rule-based criteria as to how to modify the behavior of the application according to the performance and availability of the various required resources and services. The controllers send messages to one or more actuators which effect the change in behavior of the application. A console displays the status of the system and allows users to modify the rules used to modify the behavior of the application.
1. A system for providing for the graceful degradation of the performance of a computer application, the system comprising:
at least one sensor configured to monitor an availability and/or performance of resources associated with the computer application;
a first controller and a second controller, the first controller configured to collect information from the at least one sensor and to apply rule-based criteria to the information to determine the availability and/or performance of the resources, the first controller further configured to generate at least one message to the second controller; and
a plurality of actuators configured to modify a single component of the computer application based on the information collected by the first controller.
2. The system of claim 1 , further comprising at least one console.
3. The system of claim 2 , wherein the at least one console is configured to communicate with the at least one sensor.
4. The system of claim 3 , wherein the at least one console is configured to communicate with the at least one sensor through at least one of the first and second controllers.
5. The system of claim 2 , wherein the at least one console is configured to communicate with the plurality of actuators.
6. The system of claim 5 , wherein the at least one console is configured to communicate with the plurality of actuators through at least one of the first and second controllers.
7. The system of claim 1 , wherein the first and second controllers are arranged in a master/slave hierarchy.
8. The system of claim 1 , wherein the computer application is a web-based application.
9. The system of claim 1 , wherein the computer application is a multi-tiered client/server application.
10. A method for providing for the graceful degradation of the performance of a computer application, the method comprising:
receiving with a plurality of controllers data from at least one sensor, the data indicative of an availability and/or performance of resources associated with a computer application;
applying rule-based criteria to the data to determine the availability and/or performance of the resources;
generating at least one message with a first controller of the plurality of controllers to a second controller of the plurality of controllers, the message indicative of said determination;
instructing a plurality of actuators or at least one of the plurality of controllers to modify a behavior of the computer application based at least on said determination; and
modifying a single component of the application with the plurality of actuators.
11. The method of claim 10 , wherein said applying further includes determining a course of action based on the data received from the at least one sensor.
12. The method of claim 10 , additionally comprising monitoring with a plurality of sensors the availability and/or performance of resources associated with the computer application.
13. The method of claim 12 , wherein said monitoring comprises monitoring a single component of the application with the plurality of sensors.
14. The method of claim 12 , wherein said monitoring includes monitoring performance characteristics identified by a user.
15. The method of claim 10 , wherein the first controller and the second controller are arranged in a master/slave hierarchy.
16. The method of claim 10 , additionally comprising modifying a behavior of the at least one sensor with at least one of the plurality of controllers.
17. The method of claim 10 , additionally comprising receiving at least a portion of the rule-based criteria from a user.
18. A system for providing for the graceful degradation of the performance of a computer application, the system comprising:
means for monitoring an availability and/or performance of resources required by a computer application;
means for receiving information from the monitoring means and for applying rule-based criteria to the information to determine the availability and/or performance of the resources, the means for receiving and applying further comprising a means for generating a message to a controller of said means for receiving; and
means for modifying a behavior of the computer application based on the information collected by the monitoring means, the means for modifying comprising a plurality of actuators configured to modify a single component of the application.
19. The system of claim 18 , additionally comprising means for displaying the performance of at least a portion of the resources required by the computer application.
