The invention relates to the technical field of cloud computing, in particular to a monitoring frequency dynamic adjustment method suitable for cloud computing. The method comprises the steps that monitoring frequency related parameters are set, and a stable variation coefficient is calculated through a stable variation coefficient formula after sampling; the stable variation coefficient is compared with a frequency adjustment threshold value; whether the monitoring frequency is increased or decreased or maintained is determined according to the comparison result. According to the method, the dynamic adjustment problem of the monitoring frequency of all resources of a virtual machine in cloud computing is solved; the method can be used for monitoring the virtual machine.
