Traffic collection method and device, equipment and storage medium

Abstract

The technical scheme of the embodiment of the invention discloses a traffic collection method and device, equipment and a storage medium. The method comprises the following steps: acquiring a target data packet in a virtual network, and extracting data packet information contained in the target data packet; acquiring pre-configured acquisition point information, and comparing the data packet information with the pre-configured acquisition point information; and collecting a target data packet according to an information comparison result so as to carry out traffic analysis. According to the method, local information analysis can be performed on the data packets in a virtual network environment formed by a plurality of servers, and whether repeated data packets exist or not is determined, so that the traffic receiving equipment receives the data packets without repeatability, the capability requirement on the traffic receiving equipment is reduced, and the network bandwidth consumption caused by repeated traffic collection is reduced; and misjudgment caused by comparison of complete data packet contents can be reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of computer network performance monitoring, and in particular, to a flow collection method, device, equipment and storage medium. Background technique [0002] Traffic collection is a prerequisite for computer network performance monitoring. In virtual network environments such as virtualization and containers, there are virtual switches in physical servers and virtual machines, so that two virtual machines or containers can communicate directly without going through a physical switch. Usually, when collecting traffic, all virtual network card traffic will be collected on the virtual switch. For example, when virtual machine A sends a data packet to virtual machine B, the data packet will be mirrored on the virtual network cards of virtual machine A and virtual machine B respectively to the traffic receiving device. Obviously, this traffic collection and analysis method will cause...

However, relying on the deduplication capability of the traffic receiving device for deduplication is a way of deduplication after collection. Repeated traffic collection will lead to additional consumption of network bandwidth; and deduplication requires comparison of the complete data packet content. Yes, it may cause deduplication misjudgment and affect the accuracy of traffic analysis
