Amir  Said - PeerSpot reviewer
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.
Leandro Di Maria - PeerSpot reviewer
Offers real-time monitoring capabilities, which help businesses optimize their operations
The tools are part of managed environments, but when the capabilities of the routers need to be increased, we use NETSCOUT to manage things at an international level. The tool's user interface is okay. It would be great if the tool could provide alerts during attacks in Spanish. In the next release, if the traffic analysis could send our company an alert before an attack starts, it would be even better. Before an attack starts, seeing the traffic behavior and activities would be great. The tool should also share alerts since it is an area where the product has certain shortcomings.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"An excellent solution that is easy and intuitive to implement."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"This is a very good solution and it is simple to use, for any company."
"The solution is pretty stable."
"Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools."
"You want to monitor a specific metric that nobody else has? You can do it even with the most basic of scripting skills, and you can always share it with the vast community of Nagios Exchange."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"The solution has a lot of plugins and scripts integrated with it."
"The solution's technical support team consists of good engineers and technicians."
"This is a very reliable and complete solution for troubleshooting and monitoring environments."
"I like the single pane of glass view because it presents everything in one window, obviously. You can see it all. With a quick glance, you get a pretty good snapshot of what's going on in a particular situation."
"The most valuable feature of NETSCOUT nGeniusPULSE is the network troubleshooting analysis. You can pinpoint an issue before it could shut down the network."
"I like the single pane of glass view. I like being able to go to one place instead of having to hunt around for everything."
"The most valuable features of this solution are monitoring and maintaining traffic queuing, as well as seeing who is using the bandwidth."
 

Cons

"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."
"The product's stability could be even better."
"The GUI could be improved."
"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"Open-source software is usually not user-friendly."
"The Configuration Wizard needs improvement, because not all vendors are present."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"The reporting structure could be more streamlined."
"In terms of additional features, I would like to see better event notification. Right now, we put in an email address to receive an alert and it receives every event and every alert that comes out. We need something a little more granular."
"The GUI interface and dashboards could be more attractive to the customer."
"Before an attack starts, seeing the traffic behavior and activities would be great. The tool should also share alerts since it is an area where the product has certain shortcomings."
"They require a lot of manual effort as traffic flows, networks, and formal times change."
"Usability is the area with the biggest room for improvement. We've found that with NETSCOUT, while it's a fantastic product, the usability is a major factor because there are just way too many clicks. It's obvious, from our experience, that the people who are developing the product aren't using it."
"The price of the solution could be reduced."
