Introduction – Best Network Monitoring Tools
Network monitoring is the practice of continuously overseeing and analyzing the performance, availability, and security of a computer network or IT infrastructure. It involves collecting data and information from various network devices, systems, and applications to ensure that the network operates efficiently, meets performance expectations, and remains secure. Network monitoring plays a critical role in maintaining the reliability and functionality of modern networks, whether they are small local area networks (LANs) or large, complex wide area networks (WANs) and data center environments.
Network monitoring is crucial for maintaining the performance, security, and overall health of your network infrastructure. There are various tools available to assist with network monitoring, and they can be broadly categorized into different types based on their functionalities.
