A disk access request monitoring system and method thereof in a virtualized environment

Abstract

The invention discloses a disk access request monitoring system and method in a virtual environment. The disk access request monitoring system is deployed in a privilege virtual machine, and is used for monitoring disk access requests of a plurality of client virtual machines. The disk access request monitoring system comprises an initialization module, a disk access request monitoring module and a monitoring information storage module, wherein the initialization module is used for creating log files and arranging monitoring points, the disk access request monitoring module is used for monitoring the disk access requests sent by the client virtual machines at the same time, and the monitoring information storage module is used for storing and recording obtained monitoring information.

Description

technical field [0001] The invention relates to the monitoring of disk read and write requests in a virtualized environment, in particular to the monitoring of fine-grained disk access requests divided according to virtual machines. Background technique [0002] Virtualization technology was born in the 1960s. IBM proposed the concept of virtualization and applied this technology to IBM's System / 370 system. So far, virtualization technology has been applied in many industries and fields, and will be used more widely in the future. Through the virtualization technology, the resource utilization rate of the server can be improved, the stability and robustness of the service and the portability of the software can be improved. [0003] Xen is a widely used virtualization software. Its main components are the virtual machine management layer (Virtual Machine Monitor, hereinafter referred to as VMM), the privileged virtual machine Domain0 (hereinafter referred to as Dom0) contai...

[0007] A document titled "Online Storage Performance Management in Virtualized Datacenters." was published in "Proceedings of the 2nd ACM Symposium on Cloud Computing" , the authors are: AjayGulati, Ganesha, Irfan Ahmad, Carl Waldspurger, Mustafa Uysal.Pesto, the publication date is: October 26, 2011, and a tool for analyzing virtual storage performance is specifically disclosed in the document, which is mainly deployed in VMware The sSphere monitors some statistical information of the virtual disks of each virtual machine, but the information does not have too many details, and there are no more records of each IO operation, which cannot provide enough help for analyzing the behavior of the application

[0008] A paper titled "Scalable I / O Tracing and Analysis (scalable I / O tracing and analysis)" was disclosed in "Proceedings of the 4th Annual Workshop on Petascale DataStorage" The literature, the authors are: KarthikVijayakumar, FrankMueller, Xiaosong Ma, Philip C.Roth, the publication date is: November 14, 2009, a kind of event that collects various levels of high-performance IO applications is disclosed in the literature. However, this method Only applicable to stand-alone environment, does not consider the use of virtual environment

[0009] In the title "In Proceedings of the 23rd Annual Computer Security Applications Conference (the 23rd Computer Security Application Conference)" published a document titled "Secure and Flexible Monitoring of Virtual Machines (safe and flexible virtual machine monitoring technology)", the author is : Bryan D.Payne Martim D.P.de A.Carbone Wenke Lee, public date is: on August 23, 2007, discloses a kind of method that guesses its access behavior to disk by analyzing the sector information of disk access in the document, This method needs to rely on specific file system information, so it is not universal
