Problems solved by technology

The advantage of the first method is that the existing monitoring resources can be used, but it is necessary to modify the network protocol driver or add new network hardware devices
The second type of method is relatively common, but relies on the configurability of virtual switches and lacks performance optimization capabilities. At the same time, the monitoring of communication traffic between virtual machines and the outside world can only be handled by external monitoring devices, lacking unified monitoring management capabilities

Embodiment Construction

[0029] The invention provides a unified monitoring system for the flow monitoring between virtual machines and the flow monitoring between the virtual machines and the server external network. Initialization stage: Start the virtual machine containing the monitoring module on the virtual machine monitor, deploy the packet capture module and data cache module to the kernel, establish a connection between the monitoring module and the data cache module, and send the filter address list to the kernel from the monitoring module Send the startup command to the kernel, and the monitoring system is deployed.

[0030] In the present invention, both the data packet capture module and the data cache module run on the kernel, and are loaded into the kernel through the kernel programming interface before running. Since the monitoring module is deployed in the virtual machine, and the virtual machine runs in the user state, it is necessary to build a communication connection between the ke...

Abstract

The present invention discloses a virtual machine traffic monitoring method and system. Firstly, a virtual machine comprising a monitoring module is started; a data packet capture module and a data cache module are deployed in a virtual machine monitor core; the data packet capture module copies a data packet passing a TCP/IP protocol stack according to a filtering mechanism, and stores the data packet to a cache of the data cache module; the data cache module forwards the data packet in the cache to the monitoring module; the monitoring module performs statistics analysis on the data packet, so as to monitor the traffic of the virtual machine. A problem that communication between virtual machines is not monitored due to virtualization of a server is solved, and communication between virtual machines on the same physical server and communication between the virtual machine and the external network of the server are monitored in a unified way.

Description

technical field [0001] The invention relates to server virtualization virtual machine flow monitoring, in particular to a virtual machine flow monitoring method and system on a physical server. Background technique [0002] Server virtualization can improve the utilization of computing resources and enhance the management flexibility of IT resources. Therefore, this technology has become an important technology in current data centers. However, after server virtualization, there are multiple virtual machines on the same physical server, and the communication between these virtual machines cannot be sensed by the monitoring system deployed outside the physical server. [0003] Existing methods are implemented through traffic redirection strategies, including two types, one is to redirect virtual machine traffic to a network device outside the server for monitoring and processing. Another type is to redirect the traffic of the virtual machine to a virtual machine on a virtual...
