Embodiment Construction

[0069] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some embodiments of the present invention, rather than Full examples. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

[0070] The flame graph shows the running time distribution of each function in a global view, enabling program developers to clearly discover all functions that may cause performance bottlenecks, and is a powerful tool for performance analysis and debugging optimization. The flame graph visually displays the function call chain in the program. Each column in the flame graph represents a call chain (or call stack), and ...

Abstract

The embodiment of the invention provides a flame graph analysis method and device, electronic equipment and a readable storage medium. The method comprises the steps of acquiring multiple flame graphs used for program performance analysis; extracting sub-path feature information of sub-paths in each flame graph; based on the sub-path feature information between every two flame graphs, determining the similarity between every two flame graphs so as to determine the similarity between all the flame graphs in the plurality of flame graphs; and on the basis of the similarity among all the flame graphs, clustering all the flame graphs respectively. According to the embodiment of the invention, the method for measuring the similarity between the flame graphs by using the sub-path characteristics in the flame graphs is provided, so that the flame graphs with high similarity can be clustered, and when an analyst analyzes the flame graphs, only one or more of the flame graphs belonging to the same type need to be extracted for manual analysis, so that the manual analysis cost of the flame graphs is greatly reduced.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a flame graph analysis method, a flame graph analysis device, an electronic device and a computer-readable storage medium. Background technique [0002] At present, when performing performance analysis on the operation of various games, it is realized by collecting and drawing the corresponding performance flame graph. The flame graph shows the running time distribution of each function in the program in a global view, so that program developers can Clearly discovering all functions that may cause performance bottlenecks is a powerful tool for performance analysis and debugging optimization. Since most of the game processes on the platform run continuously for a long time, a large number of flame graphs will be generated during the process, and a lot of labor costs are required to screen and analyze the flame graphs. Contents of the invention [0003] In view of the ...
