Method and device for collecting and storing performance data of cloud computing system

Abstract

A method and an apparatus for acquiring and storing performance data of a cloud computing system are provided by the present application. The method is applied to each host in a cloud computing system, and comprises: acquiring local performance data according to a preset sampling period, parsing a user stack of a process using register values of a local CPU, so as to derive the function call chain of the process at the acquisition time and a DSO file corresponding to each function; and storing the acquisition time as a keyword and the performance data as a key value into a database correspondingly. A method, an apparatus and a system for detecting the performance of a cloud computing system are also provided by the present application. The method comprises: in response to a request from a user for detecting the performance of the cloud computing system, acquiring the target data correspondingly, and detecting the performance of the cloud computing system on the basis of the target data. With the present application, the distributed data storage is achieved, the unnecessary network overhead is avoided, and the performance data from a plurality of machines can be aggregated and parsed, and thus the performance analysis of the cloud computing system is realized.

Description

technical field [0001] The present application relates to the field of cloud computing, in particular to a method and device for collecting and storing performance data of a cloud computing system, and a method, device and system for detecting performance of a cloud computing system. Background technique [0002] The cloud computing system includes massive basic hardware resources such as servers, storage, and networks, and massive basic software resources such as stand-alone operating systems, middleware, and databases. The hardware composition of the cloud computing system can be regarded as a computer cluster, and there may be thousands of machines involved. For users of cloud computing systems, the cost is usually proportional to the hardware resources occupied by the application. The more hardware resources used, the higher the cost. Therefore, providing performance analysis tools for cloud computing systems to help developers and users of cloud computing systems opti...
