A virtual machine process traffic monitoring method based on sflow

Abstract

The invention discloses a sFlow based virtual machine process traffic monitoring method and relates to the technical field of cloud computation. The sFlow based virtual machine process traffic monitoring method includes that a process monitoring program acquires running process information in virtual machines periodically and transmits the process information to a traffic monitoring program; the traffic monitoring program extracts relevant information to construct an uplink traffic table and a downlink traffic table respectively from sFlow messages transmitted by virtual switches; the traffic monitoring program extracts relevant information to construct a process table from the received process information; the traffic monitoring program periodically scans each record of the process table and extracts relevant parameters to make up keywords and respectively looking up the uplink traffic table and the downlink traffic table to calculate uplink and downlink speed of each process of each virtual machine. By the sFlow based virtual machine process traffic monitoring method, consumption of processor and memory resources of the virtual machines are reduced, the processor and memory resources of the virtual machines are saved, network delay of the virtual machines is reduced, and processing capacity of users' businesses within unit time is improved.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to an sFlow-based virtual machine process flow monitoring method. Background technique [0002] In a cloud computing data center, a large number of virtual machines share network resources. When a process in a virtual machine generates abnormal traffic and affects the network, it will cause network abnormalities of other virtual machines. The machine process traffic monitoring finds out the virtual machine that generates abnormal traffic, and shuts down the process, so that the network of the data center can be restored to normal. [0003] At present, the common method for monitoring the flow of virtual machine process is: install a network monitoring program in the virtual machine, copy the data packets flowing through the network card of the virtual machine, and perform statistical analysis on the data packets, so as to obtain the flow of each process, and convert the stat...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is that the network monitoring program copies each data packet flowing through the network card of the virtual machine, which occupies more processor and memory resources of the virtual machine, increases the network delay of the virtual machine, and reduces the processing time of the user business unit. ability
