A suitable choice for unified and efficient infrastructure monitoring across diverse environments providing user-friendly GUI, cost-effectiveness, and versatility
We use it for this specific client, they've deployed multiple instances of it across various locations to facilitate monitoring. To effectively monitor their infrastructure, it seems necessary to implement additional monitoring solutions for all three types of devices they have Nagios Fusion…

Monitoring has improved bandwidth insights and application diagnosis but setup and costs still need work
They need room for improvement about the spare parts. There are shortages in Egypt in their stock. We tried to make RMA for specific parts, and it took a long time. Comparing this to a vendor like Cisco, who provides any component next business day, NETSCOUT nGeniusONE took a long time. This needs more improvement. I believe it is expensive. They need to reduce its budget a little bit. Comparing to other solutions, it is very expensive.

Quotes from Members

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

Pros

"Being open source lets us customize it for our monitoring needs, saving us money."
"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."
"It is easier for client installation, and the configurations are doable even for a newcomer in the field."
"It's very easy to manage and monitor it."
"The real-time insights that NETSCOUT nGeniusONE provides are very helpful."
"When we have mobile operators who are signal partners, where one is the roaming host and another is the roamer, we are able to see their traffic. Their packets are able to detect if any faults to develop, and at what point they fail."
"From a troubleshooting perspective, it allows us to quickly search all data TAP points in the network and helps our network engineers get to root cause quickly."
"It has cut our group's troubleshooting time down significantly, e.g., depending on the issue, what would normally take maybe a couple of hours will now take minutes."
"If one of our network pipes is getting plugged up by somebody using too much bandwidth, we can use the NETSCOUT tool to examine and find out what is going on."
"Deep packet inspection is probably the strongest feature."
"When it's implemented properly, and the training is there to use the interface and have it work in your company, and people understand it, it can be very effective."
"The most valuable features are speed and cost."
 

Cons

"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."
"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."
"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
"The stability is okay, but sometimes we see that the memory on the server is not 100 percent correct and we need to stop and start the software to have it reallocated again."
"We would like more encryption of customer data, because we have a very security conscious company. We have a lot of regulation coming in which requires us to make customer data private."
"There are so many pieces of their product that integrate with one another that perhaps a recommendation for improvement would be some sort of bigger overview and map to help understand how all their pieces integrate together."
"Being able to manage the packet flow switches in nGeniusONE would be great."
"Its initial setup process is complicated."
"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."
"They can increase flexibility in the search engine. Basically, I go with the information I have at the time. If I could just type in the parameter that I want to search for and its value, it might be easier than having to do the groundwork upfront before I can get my traces."
"Datadog is more stable than NETSCOUT nGeniusONE, being a SaaS-based solution compared to on-prem solutions like NETSCOUT."
 

Pricing and Cost Advice

"The pricing is quite reasonable, especially when compared to the broader market."
"It is very expensive, but it's well worth the money."
"The biggest problem we have with this product is the expense."
"The product is too expensive compared to other products."
"Cost is probably the biggest drawback. Compared to some of the newer vendors that have popped up in the space, it's definitely more on the expensive side... [But] it's been able to keep its value, even in the face of the cheaper competition."
"It was pretty modest because you could get it in different ways. I think the six licenses, at that time, were about $1,000 each. But then again, I work for a school and educators tend to get discounts on things. So maybe it cost us about five or six hundred a copy."
"Their pricing is very competitive with other solutions... But what I like about NETSCOUT's licensing is that it's shared across all their platforms. They don't create a new licensing scheme for every one of their products. So for nGeniusONE, you buy a certain license level, and it works on all of their products."
"There is a need to make yearly payments towards the licensing charges attached to the product. The product may come across as a cheap tool for some, while it may seem costly for others."
"Like any company, we always want better pricing. The pricing is okay, but it's not a cheap solution. When you want to deploy it across an enterprise as large as ours, you go into seven figures. It's not a cheap solution to get out there."
