Embodiment Construction
[0068] An abnormal load detection method for cloud computing online services proposed by the present invention uses historical load data of online services to detect abnormal loads of online services through wavelet analysis and statistical analysis. The method is described in detail in conjunction with drawings and embodiments as follows.
[0069] The method process that the present invention proposes is as figure 1 shown, including the following steps:
[0070] Step 1) Use the fixed-period sampling method to collect the information data of each load item of all hosts carrying an online service, mainly including CPU usage, memory usage, disk I / O rate and network I / O rate, recorded as in Indicates the load statistics data at a certain time point i, i=1,2,...,n; n is a positive integer; x indicates the use of any one of the host's CPU, memory, disk I / O or network I / O Rate;
[0071] In this embodiment, CPU usage is used for illustration. For the CPU usage, the default is...
