Top 10 Best Network Monitoring Tools (2020 Rankings)

A Comprehensive List Of The Best Paid And Free Network Monitoring Tools And Software In 2020:

Network Monitoring is the process of monitoring network components like routers, switches, firewalls, servers, etc.

Network Monitoring Tool is an application that gathers useful information from different parts of the network. It will help in managing and controlling the network. The focus of network monitoring will be on performance monitoring, fault monitoring, and account monitoring.

Network Monitoring Tools

It is used for examining the components like applications, email servers, etc. In order to examine the network or its internal components, it sends a signal or Ping to the various system ports. Network Monitoring should be proactive and that will help in finding the problem at an early stage. It has the capability to prevent downtime or failure.

The Below image will show you the important factors of Network Monitoring.

Factors of Network Monitoring

Let's see the precise description for each step of the above diagram.

The first step from the figure can be called as ‘Monitoring the Essentials’. Faulty network components can hamper the network’s performance. Continuous network monitoring needs to be performed in order to avoid this. Hence, the first step of this process is to monitor such devices and performance metrics.

The second step will be deciding the monitoring interval. Monitoring interval depends on the network components. Example: Components like desktop and printers don’t require frequent monitoring while the components like servers and routers need frequent monitoring.

Network management protocol should be secure and non-bandwidth consuming. Network management protocol will minimize its impact on network performance. Linux servers and maximum network devices use SNMP (Simple Network Management Protocol) and CLI protocols. Windows devices use WMI protocol.

SNMP agent is enabled and configured to have communication with the Network Management System (NMS). SNMP Read & Write access will give someone the entire access for the device.

Real-time network monitoring should be able to find the performance bottlenecks proactively. The threshold will play a major role in this. Threshold limits will change, according to the device and business use case. Thus you need to configure the threshold for proactive network monitoring.
