It follows that the detailed description of the invention of the present invention is described by combining explanation accompanying drawing, in order to the technology of this area
Personnel are more fully understood that the present invention.It is significant to note that, in the following description, when retouching in detail of known function and design
When stating the main contents that perhaps can desalinate the present invention, these are described in and will be left in the basket here.
Fig. 1 is the fault diagnosis schematic diagram of the present invention, by diagnostic cast at historical data training, then uses diagnosis mould
Type carries out data analysis to the data of Real-time Collection, it is judged that whether it is fault.
Fig. 2 is the detailed description of the invention flow chart of data acquisition module of the present invention, reflects the whole process of data acquisition.
Which resource is step 201: user arranges relevant parameter, such as, to gather and (calculate resource, storage resource, network
Resource) the acquisition interval time etc..
Step 202: carry out data acquisition by VMwarevSphere SDK.
Step 203: the data of collection are stored in data base.
Fig. 3 is the data collection strategy figure of the present invention.The data collection strategy of native system is that one gathers plan coarseness
The tactful mode slightly combined with fine granularity acquisition strategies.
Traditional data acquisition modes by arranging certain time interval, timing virtual machine performance index is adopted
Collection.If the time interval of the data acquisition arranged is less, data acquiring frequency is relatively big, then can seriously consume resources of virtual machine,
Affect the normal use of user.If the time interval of the data acquisition arranged is relatively big, the frequency of data acquisition is less, during unit
In the virtual-machine data that collects few, can not well reflect the practical operation situation of virtual machine.
