The fault correlation method of the present embodiment, as Figure 1-1, comprises the following steps:
Step S101: receiving the source fault message that the source of trouble reports, source fault message includes the position of the source of trouble
Information；
In this step, the source of trouble reports the relevant information of the fault of self, i.e. reports source fault message.Pipe
Reason end receives this source fault message.The positional information of the source of trouble here refers to where break down, specifically
At which layer, which resource node etc..
Step S102: obtain the generation time of the source of trouble；
In this step, the generation time here refers to the time that fault produces.
Step S103: search corresponding resource topology tree according to the time of generation；
In this step, for virtualized environment, according to different deployment strategys, different hardware shapes
State, the relation between each layer resource is dynamically change, i.e. resource topology tree is continually changing, for standard
The true fault finding fault correlation, then resource topology tree accurately will be found.Here corresponding resource
Topological tree refers to that this source of trouble produces the resource topology tree corresponding to time of fault.
Step S104: obtain the relevant fault of the source of trouble according to positional information and resource topology tree.
In this step, after determining resource topology tree, it is possible to the position letter occurred according to this source of trouble
Breath finds its relevant fault.Citing illustrates, as shown in Figure 1-2, and virtual network function management VNFM
Resource topology tree graph when i.e. application layer management node receives the source fault message that the source of trouble reports, at this figure
In, virtual application 1 creates fault B owing to postponing at 00:01, just fault B is reported at 00:04
VNFM, when 00:02, the empty machine 1 of this virtual application 1 correspondence moves to main frame 2 from main frame 1, and
And the empty machine at now this application place, move to main frame 2 from main frame 1, i.e. at this point for empty machine 1
Saying, the resource node of its upstream physical resource layer is main frame 2；Fault C is created, at main frame 1 at main frame 2
Create fault A.As Figure 1-3, for producing resource topology tree graph during fault, now, virtual application
