Failure impact analysis of network events

1. A method comprising:

generating, by a control system managing a resource group, a resource graph that models resource and event dependencies between a plurality of resources within the resource group;

detecting, by the control system, a first event affecting a first resource of the plurality of resources, wherein the first event is a network event;

identifying, by the control system and based on the dependencies modeled by the resource graph, a second resource that is expected to be affected by the first event, wherein identifying the second resource includes:

generating, based on the dependencies modeled by the resource graph, a second event caused by the first event, wherein the second event is a logical event, and

identifying the second resource as a resource associated with the second event;

detecting, by the control system and after generating the second event, a third event affecting the second resource, wherein the third event is a network event; and

merging, by the control system, the third event into the second event to avoid duplicative processing associated with the third event.

2. The method of claim 1 , further comprising:

identifying, by the control system and based on the dependencies modeled by the resource graph, a third resource that is expected to be affected by the first event.

3. The method of claim 2 , wherein identifying the third resource includes:

generating, based on the dependencies modeled by the resource graph, a fourth event caused by the second event, wherein the fourth event is a logical event; and

identifying the third resource as a resource associated with the fourth event.

4. The method of claim 1 , wherein generating the second event includes:

determining that the second resource has both resource and event dependencies on the first resource.

5. The method of claim 1 , further comprising:

detecting, by the control system and before generating the second event, a fourth event affecting the second resource, wherein the fourth event is a network event; and

merging, by the control system and after generating the second event, the second event into the fourth event.

6. The method of claim 1 , further comprising:

applying, by the control system, the resource graph to generate a plurality of inference rules with respect to the plurality of resources modeled by the resource graph.

7. The method of claim 1 , further comprising:

performing, by the control system, a forward chaining analysis to identify the second resource.

8. The method of claim 1 , wherein generating the resource graph includes:

receiving programming input; and

generating the resource graph based on the programming input.

9. The method of claim 1 , wherein generating the resource graph includes:

applying temporal constraints to each of the dependencies modeled by the resource graph.

10. A system comprising:

a network including a plurality of resources; and

a controller capable of communicating with each of the plurality of resources and configured to:

generate a resource graph that models resource and event dependencies between a plurality of resources within a resource group,

detect a first event affecting a first resource of the plurality of resources, wherein the first event is a network event,

identify, based on the dependencies modeled by the resource graph, a second resource that is expected to be affected by the first event, wherein to identify the second resource, the controller is further configured to:

generate, based on the dependencies modeled by the resource graph, a second event caused by the first event, wherein the second event is a logical event, and

identify the second resource as a resource associated with the second event,

detect, after generating the second event, a third event affecting the second resource, wherein the third event is a network event, and

merge the third event into the second event to avoid duplicative processing associated with the third event.

11. The system of claim 10 , wherein the controller is further configured to:

identify, based on the dependencies modeled by the resource graph, a third resource that is expected to be affected by the first event.

12. The system of claim 11 , wherein to identify the third resource, the controller is further configured to:

generate, by applying the dependencies modeled by the resource graph, a fourth event caused by the second event, wherein the fourth event is a logical event; and

identify the third resource as a resource associated with the fourth event.

13. The system of claim 10 , wherein to generate the second event, the controller is further configured to:

determine that the second resource has both resource and event dependencies on the first resource.

14. The system of claim 10 , wherein the controller is further configured to:

detect, before generating the second event, a third event affecting the second resource, wherein the third event is a network event; and

merge, after generating the second event, the second event into the third event.

15. The system of claim 10 , wherein the controller is further configured to comprising:

apply the resource graph to generate a plurality of inference rules with respect to the plurality of resources modeled by the resource graph.

16. A non-transitory computer-readable storage medium comprising instructions that, when executed, configure processing circuitry of a computing system to:

generate a resource graph that models resource and event dependencies between a plurality of resources within a resource group;

detect a first event affecting a first resource of the plurality of resources, wherein the first event is a network event;

identify, based on the dependencies modeled by the resource graph, a second resource that is expected to be affected by the first event, wherein to identify the second resource, the processing circuitry is further configured to:

generate, based on the dependencies modeled by the resource graph, a second event caused by the first event, wherein the second event is a logical event, and

identify the second resource as a resource associated with the second event,

detect, after generating the second event, a third event affecting the second resource, wherein the third event is a network event and

merge the third event into the second event to avoid duplicative processing associated with the third event.
