Embodiment Construction

[0073] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0074] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0075] Such as figure 1 As shown, the network monitoring system 1 is deployed in the Dom0 kernel space under the virtualization environment, and the user does not need to provide any other information. Since the network access behavior of all DomUs on the same physical machine needs to go through the back-end network card driver of Dom0, a monitoring point function is added where the back-end network card driver performs the operation of receiving data packets and sending data packets, so that each time there is When the data is driven by the back-end device, it can be recorded through the monitoring point mechanism.

[0076] This preferred embodiment adopts ...

Abstract

The invention discloses a network monitoring system and a method thereof in the virtual environment. The network monitoring system is disposed in a privilege virtual machine to carry out network monitoring over a plurality of client virtual machines. The network monitoring system comprises an initialization module, a data transmission monitoring module and a data reception monitoring module. The initialization module is used for creating log files and arranging monitor points. The data transmission monitoring module and the data reception monitoring module are used for simultaneously monitoring external transmission data and reception data of the plurality of client virtual machines respectively, and storing obtained monitor information to be used in the network monitoring. The invention achieves the fine grit network monitoring system and the method thereof in the virtual environment.

Description

technical field [0001] The invention relates to network request monitoring in a virtualized environment, in particular to fine-grained network access request monitoring 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 virtualization technology, the utilization rate of servers can be improved, the stability and robustness of services and the portability of software can be improved. In addition, virtualization technology also provides a way to solve system security problems due to its excellent isolation . [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), ...
