1 results about "Application performance management" patented technology

The application relates to a public cloud multi-tenant performance monitoring method, device, equipment, storage medium and program product. The method comprises the following steps: collecting a plurality of low-level indexes of a cloud application runtime on a host of a target virtual machine node and a target virtual machine; the low-level indexes comprise at least one of CPU utilization, a hardware counter, a host resource state, resource usage characteristics, a hardware event vector and interference intensity; inputting the plurality of low-level indexes into a proxy model for performance evaluation to obtain a first evaluation result; the first evaluation result comprises a target performance degradation estimation value, a performance degradation reason of the cloud application and a contribution degree of the degradation reason; the target performance degradation estimation value is used for representing a degradation degree of the cloud application; and performing degradation evaluation according to the first evaluation result to obtain a second evaluation result. The above method improves the resource utilization rate and cost efficiency of the public cloud infrastructure, and further enhances the foresight and accuracy of cloud application performance management.
