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.

Quotes from Members

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

Pros

"This is a very good solution and it is simple to use, for any company."
"Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools."
"The Script Module in Nagios is really easy to use and is really cost efficient."
"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"The most valuable feature of Nagios XI is customization. We can customize based on our requirements. We can do modifications and implement a lot of scripts. Additionally, it is easy to use."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"The technical support is really good. They will go above and beyond, if you are running into a problem. You can go to a sales engineer, who will engage technical support to help you out."
"The most valuable feature is utilization."
"The real-time troubleshooting and application segregation that you can do within it."
"It's an easy product to set up."
"It allows us to get quicker resolutions. We can see exactly what is using up the bandwidth, so we can assist end users."
"It has cut our troubleshooting down by days. Once we have a product in place, we show people examples of how it can streamline their troubleshooting process."
"It is very rock solid. We hardly have any hardware issues."
"It helps us to assist our customers to isolate problems. If it is us who is having the problem, then we can use it to streamline the process."
 

Cons

"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"I would like to see support for notification via SMS."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"The Configuration Wizard needs improvement, because not all vendors are present."
"The product does not have SAP monitoring."
"The reporting part should be made simpler. While we can obtain all the reports we need, we always have to create work-arounds to get them."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"We don't use the single pane of glass view, even though we own it."
"The NetFlow Collectors could handle more flows per minute."
"The monitoring and reporting tool needs improvement. Users want more information, such as the level of detail when doing a packet analysis. They want more detail to be able to isolate down to a specific point."
"It's not able to communicate with our probes."
"Being able to manage the packet flow switches in nGeniusONE would be great."
"I'd like them to make the product more user-friendly."
"Only problems that we have had are fiber issues going into the TAPs or vSTREAMs, which are usually local site issues."
"I would like to see an improved level of stitching between IPs."
 

Pricing and Cost Advice

"Nagios XI is open source."
"We are using the free version of this solution."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"The pricing is high with separate licensing for the product and support."
"Nagios XI is an expensive solution."
"Licensing costs are reasonable."
"As it is not an agentless tool, I think it is expensive."
"The licensing fees for this solution are approximately $3,000 USD per year."
"The price is a little high."
"It can be scalable. It just costs too much. With a company as big as ours, it gets too expensive to accommodate every single site."
"The scalability is good, but it comes at a cost. E.g., if you need 100 InfiniStream because you are sending gigs or terabytes of data to one InfiniStream, then you will have to purchase another InfiniStream, which are not cheap."
"This product could be cheaper."
"I would like it to be more scalable with less spend."
"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
