For example, network traffic monitoring tools can help identify connections that send abnormal amounts of traffic to your host. Monitoring incoming traffic can help thwart network attacks and maintain the security of your Linux servers (or systems). For example, closing unused ports or restricting port access to a list of known IPs can help reduce possible attack vectors on your Linux systems. Understanding the overall state of your network, including network traffic at the interface and device levels, can provide you with insight into network performance and the security of your system. An effective network monitoring system on Linux servers should be based on three interconnected layers: general network health, incoming traffic, and outgoing traffic. It requires a systematic approach based on clear identification of goals, performance targets, and adherence to security standards. ![]() Network traffic monitoring is a crucial component of Linux system administration. This information can be used to distribute resources better. Facilitate capacity planning and resource distribution: Network traffic monitoring can also help identify applications with insufficient resources or excessive resource consumption.Network monitoring tools can help identify traffic flow patterns in your servers and help your team quickly respond to anomalies. Track security anomalies: Traffic spikes originating from remote hosts may indicate the start of DDoS attacks against your servers.These may include disconnections, closed ports, and firewall misconfigurations. Troubleshoot network issues: An efficient network monitoring system can help identify and fix network-related issues.For example, if your application is configured to perform additional traffic-intensive background jobs, this feature can be disabled to free up bandwidth for other applications. Detect network misconfigurations: Finding traffic usage patterns may help to identify misconfigurations at the network and application levels.Network traffic data can be visualized and integrated with alerts, logs, and audit systems to improve the efficiency of how your IT team handles network performance and security issues. Ensure full, real-time visibility of network traffic: Network monitoring tools perform real-time collection of network statistics capable of providing insights into the state of your network.Here's how efficient network traffic monitoring tools can help IT teams: So, understanding network traffic is a key prerequisite for your Linux servers and applications to operate seamlessly. This is especially true about Linux systems, which are widely used as production servers for hosting applications and administering networks. This means that your hosts are constantly targeted by traffic from diverse sources. Most modern applications are exposed to various remote networking services via background processes scraping data, push notifications, and web socket connections.
