What is Network Monitoring? Is it Important
The process of regularly monitoring a computer network for problems such as delayed traffic or component failure is known as network monitoring. Network monitoring tools constantly scan the network and are designed to automatically warn network administrators when an issue occurs by text, email, or another application such as Slack. Network monitoring software is distinct from network security or intrusion detection systems in that it focuses on internal network issues such as overloaded routers, server failures, or network outages.
Network monitoring systems can also start failover to remove problematic devices or circuits from service until the issue is resolved. A proactive network monitoring solution, ideally, can prevent downtime or failures from occurring by detecting anomalies that, if ignored, could lead to an outage.

Continuous monitoring is essential for ensuring network integrity. The best network monitoring tools provide visualisation or a dashboard that provides at-a-glance status of monitored network components, indicating any out-of-the-ordinary parameters that require further investigation or components such as switches, routers, firewalls, servers, and software services, applications, or URLs that may be the source of network disturbances. A network monitoring system should incorporate high-availability components for maximum efficacy, so that a hardware or software failure of systems running the network management tool can be automatically resolved by fail-over to another network monitoring installation. Network monitoring should have the following features:
- Visualisation of the whole IT and network architecture of the organisation
- Network performance monitoring, troubleshooting, and resolution.
- When problems arise, apply root-cause analysis tools.
- Dashboard with easy-to-understand visualisation tools and reports DWNLOAD NOW
What are the key benefits of Network Monitoring?
The most significant advantage of network monitoring is visibility. Visualising the flow of data across devices and networks enables network administrators to swiftly identify and repair any problems—emergent or anticipated—before outages occur.
By automating this crucial job, critical IT resources are better utilised. Time saved from putting out network fires can be spent on projects that add value to the organization’s bottom line.
Network monitoring also provides an early warning indicator of how existing infrastructure is being used, giving IT a heads-up on the need to upgrade or add capacity to specific network components.
Finally, network monitoring systems can discover unexpected spikes in network traffic that can suggest a problem is brewing, whether due to increased demand or a cyberattack, by comparing data to known baselines for a specific time of day and season.
Why is Network Monitoring important?
Network outages can have a negative influence on overall IT performance and cause availability concerns throughout the organisation. Network monitoring provides various major benefits to the organisation by allowing for the early detection of problems, including:
- Cost savings are obtained by minimising downtime and accelerating remediation by assisting with root cause analysis or displaying network elements that are over- or underutilised. Instead of constantly seeking faults, network resources can be focused on beneficial projects.
- Performance issues can be identified before they disrupt business operations or harm the customer experience.
- Network security can be improved by detecting unusual traffic or unknown devices connecting to the network. These could be early warning signs of a cyberattack or ransomware attempt.
- Early detection of usage spikes, such as login storms or seasonal traffic surges, allows network administrators to take corrective measures to ensure that consumption is not harmed.
- Rogue application use can be detected. Each business unit may want to track a certain set of applications, and network monitoring can determine which programmes and users are doing what on the network.
How does Network Monitoring work?
There are various kinds of network monitoring. Email network monitoring, for example, can comprise sending test emails and measuring the response time, whereas web server testing might entail sending an HTTP request to reach a certain page and logging the time until it is served.
First, devices and network connections are detected, as are the performance indicators associated with them. The organisation then decides how frequently each function should be monitored. Client laptops and printers, for example, are not ‘network critical’ and can have considerably longer monitoring intervals than the network backbone’s routers, switches, and servers.

To manage and monitor network elements, most network monitoring solutions use the simple network management protocol (SNMP). Most network components include an SNMP agent, which can be used to reconfigure devices, take them offline if they are operating strangely, or collect device performance data. Network monitoring systems ‘ping’ the various system ports, and if a device reports a parameter that is outside of the predefined threshold, an alert is automatically created so that remediation can take place before the equipment fails. Network components are typically pinged between once per minute and once per hour.
Some network devices, such as routers and switches, use the Internet Control Message Protocol (ICMP) to exchange data about internet protocol (IP) operations and to generate error messages when devices fail.
What are the types of Network Monitoring?
Network monitoring employs a variety of devices and protocols.
Network packet analyzers examine the data in each packet that moves through the network, and the information contained within the packets can determine if the packets are being routed correctly, if employees are visiting prohibited websites, or if sensitive data, such as personally identifiable information (PII) such as social security numbers, is being exfiltrated from the network.
Application and service monitoring focuses on the systems and devices required to maintain network integrity and ensuring they are running within normal boundaries, as well as identifying which apps are used by which business units across the organisation.
Monitoring access management guarantees that intruders do not gain access to network resources, such as if an employee unexpectedly logs in from an IP address on another continent. This can swiftly identify network vulnerabilities and assist in their remediation, as well as detect intruders before they cause harm.
Conclusion:
In conclusion, Network Monitoring serves as a crucial tool for maintaining the health and integrity of computer networks. By proactively identifying and addressing issues such as delayed traffic, component failures, or potential security threats, it empowers administrators to ensure seamless network performance. The key benefits, including enhanced visibility, optimized resource utilization, and early detection of potential challenges, underscore the importance of integrating robust Network Monitoring solutions.
The diverse methods employed, ranging from SNMP for managing network elements to ICMP for devices like routers and switches, showcase the versatility of Network Monitoring. These tools, such as Network Packet Analyzers and Access Management, play a vital role in scrutinizing packet data, ensuring security, and promptly responding to network vulnerabilities.
As organizations increasingly rely on interconnected systems, the significance of Network Monitoring cannot be overstated. It not only contributes to cost savings by minimizing downtime but also enables IT teams to focus on value-adding projects. In a landscape where network outages can have cascading effects on overall IT performance, Network Monitoring emerges as an indispensable ally, providing a proactive defense against potential disruptions and security breaches.
By embracing Network Monitoring practices and investing in sophisticated tools, organizations can safeguard their networks, enhance operational efficiency, and ultimately fortify the foundation on which their digital infrastructure relies.
