Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.
Ruslan Melnyk - PeerSpot reviewer
Useful for network performance monitoring
My manager can explain the use cases attached to the product. I am a unit leader in my company, and I don't sell the product directly to our partners or customers. In my company, I manage certain processes and a team while building, developing, and providing them with a direction for the market. NETSCOUT nGeniusONE is a good solution for network performance monitoring since it is not cloud-based. My company sells NETSCOUT nGeniusONE in eight to ten countries. I think the solution is not good for capacity planning, but it is better to help find problems in applications because not every infrastructure is good at managing working applications. I think it is a solution meant for applications. The tool is useful for solving problems attached to applications. The tool's real-time network monitoring capability was used when the product was more reactive. In our company, if we use real-time monitoring, then we need to deal with raw traffic. In our company, if we don't see any problem in the real-time systems, we have the possibility to rely on the tool since it acts like a time machine for us, which can allow us to get back to the areas of problem and solve them. I recommend the product to those who plan to use it. For many users, it can be a good monitoring system that can be scaled up in the future. I think it is a good product to start with when working systems in an environment. NETSCOUT nGeniusONE is another tool used to manage raw traffic, and I find it to integrate well into our customers' network. I am not using it actively on the system. I use the tool for network packet brokers. I rate the tool a ten out of ten.

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
