Method for identifying underlocking risks in public cloud and electronic device, and storage medium

An electronic device, comprising:

• at least one processor and at least one memory;
• wherein the at least one memory is stored with computer executable instructions;
• the at least one processor executes the computer executable instructions stored in the at least one memory, such that the at least one processor executes a method for identifying underclocking risks in a public cloud, which comprises:
• collecting frequency fluctuations of CPU units in a host in a public cloud environment, wherein each of the CPU units comprises a plurality of cores;
• collecting CPU utilization rates of tenant virtual machines in the host;
• and
• sifting out risky virtual machines from the tenant virtual machines according to the frequency fluctuations of the CPU units and the CPU utilization rates of the tenant virtual machines.

A non-transient computer readable storage medium, wherein computer executable instructions are stored in the computer readable storage medium, and the processor, when executing the computer executable instructions, implements a method for identifying underclocking risks in a public cloud, comprising:

• collecting frequency fluctuations of CPU units in a host in a public cloud environment, wherein each of the CPU units comprises a plurality of cores;
• collecting CPU utilization rates of tenant virtual machines in the host;
• and
• sifting out risky virtual machines from the tenant virtual machines according to the frequency fluctuations of the CPU units and the CPU utilization rates of the tenant virtual machines.
