- Network monitoring is crucial for ensuring security, performance, and reliability in modern IT infrastructures, helping organisations detect and respond to issues promptly.
- Different types of network monitoring, such as SNMP, flow-based monitoring, and packet capture, provide distinct insights and advantages, enabling comprehensive network oversight.
In today’s interconnected world, network monitoring is the backbone of a secure and efficient IT environment. As networks become more complex, the need for robust monitoring solutions becomes increasingly critical. Understanding the various types of network monitoring available can help organisations maintain optimal performance, enhance security, and ensure compliance with industry standards.
What is network monitoring?
Network monitoring is the process of continuously overseeing a network’s performance, health, and security. It involves tracking network traffic, devices, and servers to detect anomalies, potential threats, and performance bottlenecks. Effective network monitoring helps organisations quickly identify and address issues, minimising downtime and maintaining service quality. It is essential for both large enterprises and smaller networks, as it provides a comprehensive view of network operations.

Types of network monitoring
1. SNMP monitoring: Simple Network Management Protocol (SNMP) monitoring collects and organises information from network devices like routers and switches. It provides real-time insights into the status and performance of these devices, enabling proactive maintenance and issue resolution.
2. Flow-based monitoring: This type of monitoring tracks the flow of data across a network, analysing traffic patterns and identifying unusual activity. It’s particularly useful for detecting security threats and managing bandwidth.
3. Packet capture: Packet capture involves intercepting and logging data packets as they travel through a network. This method offers deep visibility into network traffic, making it ideal for troubleshooting complex issues and ensuring data integrity.
4. Log monitoring: By collecting and analysing log data from various network devices, log monitoring helps identify security incidents, system failures, and configuration errors. It’s a key component of maintaining a secure and compliant network environment.
5. Performance monitoring: This focuses on measuring the performance of network components, such as latency, uptime, and bandwidth utilisation. Performance monitoring ensures that all parts of the network are operating at peak efficiency.
6. Intrusion detection systems (IDS): IDS monitor network traffic for suspicious activity or known threats, providing an additional layer of security by alerting administrators to potential breaches.
