Method and device for monitoring cloud platform virtual network environment

Abstract

The invention discloses a method and a device for monitoring a cloud platform virtual network environment to realize the visualization of the cloud platform virtual network environment and the real-time monitoring of the operation state of the virtual network. In this way, problems can be spotted and positioned instantly, therefore, providing basis for fault prevention and fault solution. The method can be realized through a network server, and comprises: receiving the network traffic flow generated on the virtual machine of a cloud platform; reading the traffic flow information contained in the network traffic flow; and checking and matching the read flow information in a database before outputting a final result.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a method and device for monitoring a virtual network environment of a cloud platform. Background technique [0002] System network traffic monitoring has always been an important means of system network management. It detects network security problems through all-round monitoring and analysis of network traffic of each host in the system, thereby providing a strong guarantee for system information security. In a cloud environment, since virtualization technology can support multiple virtual machines running on a physical server at the same time, traditional host-level network monitoring systems cannot monitor the network traffic of virtual machines comprehensively, accurately and effectively, resulting in many network Security issues are hard to spot.

In a cloud environment, since virtualization technology can support multiple virtual machines running on a physical server at the same time, traditional host-level network monitoring systems cannot monitor the network traffic of virtual machines comprehensively, accurately and effectively, resulting in many network Security issues are difficult to detect

[0003] However, the virtual network monitoring system currently developed for virtual machines is mainly realized through the network components of the cloud platform server itself. The network components can only perform simple traffic monitoring functions for the physical network card of the cloud platform server, such as the real-time traffic size of the physical network card, There is no way to know the state of the internal virtual network. For example, when virtual machine 1 sends attack traffic to virtual machine 2, the attack traffic is only forwarded in the internal virtual network. Ignorance leads to the inability to discover and locate problems in time, which will greatly prolong the time period for solving problems; because it is impossible to monitor the network traffic of each virtual machine in detail, such as checking the network traffic size of a virtual machine in real time, The administrator cannot monitor the virtual network of the cloud platform in detail, such as the destination host of the access and the type of traffic, so that it is impossible to find problems in time, quickly locate the problem and solve the problem, resulting in a greatly reduced user experience. Therefore, it is imminent to realize the monitoring of the virtual network of the cloud platform
