What monitoring tool shows the number of bytes and packets that have been transferred or received?

The selected answer focuses on the 'Connections' monitoring tool, which plays a crucial role in providing insights about network traffic. This tool specifically tracks and displays real-time statistics regarding the number of bytes and packets that have been transferred or received over the network. It allows network administrators to monitor active connections, identify peak usage times, and analyze data flow more effectively.

The 'Connections' tool is fundamentally designed to give a comprehensive overview of the traffic, including both inbound and outbound data metrics. This capability is essential for diagnosing network performance issues or understanding bandwidth consumption patterns.

While other monitoring tools may have their own unique functions—such as tracking detailed traffic flows, capturing packet data, or analyzing data flow trends—they do not specifically focus on summarizing the total bytes and packets in the same straightforward manner as the 'Connections' tool. Each of these alternatives serves different aspects of network monitoring and management, leading to a clear distinction in functionality and utility within the context provided.
