Abstract

The embodiment of the invention provides a method and device for detecting I / O performance jitter, and the method comprises the steps: collecting time information corresponding to a plurality of I / O requests when the I / O requests reach a plurality of key states in a life cycle, the plurality of key states at least comprise a state in which the I / O request is issued to the disk, a state in which the disk completes the I / O request and a state in which the I / O request ends; analyzing the I / O request to obtain unique identification information of the I / O request; recording a corresponding relationship among the key state, the unique identification information of the I / O request and the time information; and according to the corresponding relationship, analyzing the time information by taking any two key states as a key interval to obtain delay analysis results corresponding to the plurality of key intervals.

Description

technical field [0001] The embodiment of this specification relates to the field of computer technology, and in particular to a method. One or more embodiments of this specification also relate to an apparatus for detecting I / O performance jitter, a computing device, and a computer-readable storage medium. Background technique [0002] In a cloud storage environment, I / O performance jitter may occur due to various reasons. To solve the problem of I / O performance jitter, the performance jitter must be detected first. At present, the blktrace tool is widely used in the industry to detect I / O performance jitter. It realizes the function of capturing I / O events of Linux storage through the blktrace module under the Linux kernel, and then performs I / O performance analysis. [0003] However, because blktrace is too focused on analyzing the block layer of the I / O stack, the analysis is not comprehensive enough and the results are too discrete to clearly show the bottleneck points...
