Network traffic refers to the data that flows through a network, and it can be measured in several ways. Monitoring network traffic can be a crucial aspect of network management, providing valuable insights into network performance, identifying potential issues, and ensuring the smooth functioning of the network. Several tools and techniques can be used to check network traffic, and the choice of approach may depend on the specific requirements and environment.
Understanding network traffic patterns can help to optimize network usage, identify bottlenecks, and improve overall network efficiency. It can also be useful for troubleshooting network problems, detecting security breaches, and ensuring compliance with network policies. Additionally, monitoring network traffic can aid in capacity planning, ensuring that the network has sufficient bandwidth to meet current and future demands.
