Network monitoring refers to the monitoring of an entire network components like routers, switches, firewalls, servers, and VMs for fault, performance and evaluated continuously to maintain and optimize their availability. Its goal is to allow sysadmins to work in a better, quicker, and more efficient manner. Network monitoring focuses on parameters such as bandwidth consumption and the availability of network devices. Some of the monitored devices include the local and Internet-based systems in an IT environment, such as databases, applications, clouds, servers, and network infrastructures. Network monitoring allows admins to ensure their networks run smoothly, effectively, and free of errors.
One important aspect of network monitoring is that it should be proactive. Finding performance issues and bottlenecks proactively helps in identifying issues at the initial stage. Efficient proactive monitoring can prevent network downtime or failures.
