Top 5 Network Monitoring Tools

Network monitoring ensures that the user does not face any issues or irregularities with the software network. This practice is carried out with the help of automated network monitoring tools that are efficient and effective.   

Let’s learn what is network monitoring, why is it important for businesses, and the tools used for this practice. We also list down the top 5 network monitoring tools for businesses to choose from.   

What is Network Monitoring?   

Monitoring is a DevOps practice that involves overseeing the entire software development and lifecycle. This practice facilitates a holistic and real-time view of the status of apps, services, and infrastructure in the production environment.   

Different types of monitoring are undertaken by the DevOps teams. Network monitoring is one such practice. It involves monitoring networking components such as routers, switches, firewalls, servers, and VMs through monitoring software to check for faults and issues such as slow traffic or component failure.  

Network monitoring is done to monitor a computer network’s health, reliability, and robustness. Based on the collected and analyzed performance data, network monitoring systems generate topology maps and actionable insights, allowing teams to track network health and identify bottlenecks.   

Network monitoring has many benefits that are as follows:   

  • Complete visibility into computer network components   
  • Optimization of network reliability and data flow  
  • Enhances software performance and productivity by reducing downtime  
  • Gives access to historical data and allows troubleshooting past network problems, helping teams avoid similar problems in future  
  • Ensure corporate compliance in evolving and complex networks   

Started as a practice in the 90s, with the evolution of computer networks, the monitoring requirements of websites and internet-based services were far much more than the traditional ways of manually monitoring the typical office LAN. The networks required constant monitoring and a manual approach could no longer serve the need.   

This gave way to the development of a generation of network monitoring tools such as Cacti, Nagios, and Zabbix. These tools provided support for standard internet protocols and were multi-platform and scalable. However, they were basic and matched the requirements of the last decade.   

With more advancements, modern network monitoring systems developed and automated tools took over. Let’s learn more about these tools and list down the top ones in contemporary times.   

Network Monitoring Tools   

Network monitoring systems consist of network monitoring tools. A networking monitoring tool is software that gathers insights from different network components to highlight the overall health of the network.   

There are three types of network monitoring tools.  

  • Tools that use Simple Network Management Protocol (SNMP) to interact with network hardware and track the real-time status and use of resources, such as CPU stats, memory consumption, bytes transmitted and received, and other metrics.   
  • Flow-based tools that monitor traffic flow to provide teams with statistics about protocols and users.  
  • Active network monitoring tools that inject packets into the network. This allows them to measure parameters such as end-to-end reachability, round-trip time, bandwidth, packet loss, link utilization, etc.  

While these were the types of network monitoring tools, some essential features make these tools effective and desirable.   

Some of the key features to look for in a network monitoring tool are:   

  • Facilitate real-time performance metrics  
  • The capability of automating the device discovery and accommodating a forced discovery  
  • Smart classification of infrastructure and mapping/ grouping of devices  
  • Capable of in-depth monitoring, issue identification, and root-cause analysis  
  • Provides support to basic security features  
  • The tool should come with an intelligent alerting system/ mechanism   
  • The tool should be scalable  

Although these tools have a lot of benefits, choosing among the available ones often is a difficult task. Choosing the suitable tool that fits the business IT environment and budget, becomes challenging.    

We list down the best network monitoring tools that give the desired results in the blog ahead.

Q1. What are monitoring tools in networking?   

Monitoring tools in networking or network monitoring tools are the software that helps experts facilitates monitoring of the network’s health and performance along with spotting faults and errors in it.

Q2. What makes a good network monitoring tool?   

A good network monitoring tool should:  
1. Give real-time performance alerts/notifications  
2. Automate device discovery  
3. Ensure the security of data   
4. Be scalable  
5. Have a smart alerting system  
6. Diagnose issues and provide root cause analysis 

Q3. How does Network monitoring help in better root cause and Log Analysis? 

Network monitoring helps in root cause analysis (RCA) and log analysis. 
Suppose you are experiencing a slowness in application usage. With the help of Networking tools, DevOps teams can easily confirm whether slowness is resultant of Network speed or Application performance issue 
ManageEngine OpManager, for example, is a network monitoring tool that comes with an RCA feature.

Q4. How does Network monitoring help in Identifying security threats?  

With network security monitoring software, DevOps teams can collect metrics around client-server communications, network payload, encrypted traffic sessions, and additional network operations to identify cybersecurity threats. Patterns in network traffic flows could also be detected through network monitoring.   
Furthermore, network monitoring tools having security monitoring as a function also generate automatic security alerts and reports. This enables DevOps teams to quickly respond to any suspicious activity and implement corrective measures timely.   
Visualization tools offered by this software facilitate the identification of malicious activities and troubleshooting of cybersecurity threats.
