Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

Easy to set up with good documentation and helpful support
I'm using it for a customer The packet flow switch is the most valuable aspect of the solution.  It's an easy product to set up. We can scale the solution if we need to. It's stable.  The documentation is well-written and quite useful. It's compatible with other products.  Under the pocket flow…

Quotes from Members

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

Pros

"I can monitor a phone on a desk to very big servers of any company."
"Nagios is the best monitoring tool that I have ever worked on."
"I really found Nagios a perfect fit for us and a good product to work with."
"The alerting system is very effective."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"An excellent solution that is easy and intuitive to implement."
"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"They have very accurate and fast support."
"We have seen a lot of return on investment: We have been able to recover radios in the field, we know exactly what is going on, we cut down fines from the service commission, and we have seen a measurable decrease in mean time to know, cutting troubleshooting down by days as we can now see the issues."
"This solution has saved us hours (three to four) per problem when troubleshooting."
"It allows us to get quicker resolutions. We can see exactly what is using up the bandwidth, so we can assist end users."
"The ability to troubleshoot customers' connectivity has been very beneficial."
"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."
"I love the single pane of glass view. It makes it easier to not have to navigate everywhere. It allows more simplistic visibility, without having to go from tool to tool to tool, or from window to window to window."
"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."
"It's an easy product to set up."
 

Cons

"While this solution works, I think that it can be improved in terms of maintenance, support, and price."
"The important separation between Interface and Core to maintain historical plugins and methods generate complexity that makes Nagios unusable for repeat work."
"We'd like to see more integration capabilities."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"The installation can get very difficult depending on what Linux flavour you are using."
"The GUI could be improved."
"The reporting structure could be more streamlined."
"Reporting items needs more improvement and need to be more flexible based on customer needs."
"Only problems that we have had are fiber issues going into the TAPs or vSTREAMs, which are usually local site issues."
"I'd like them to make the product more user-friendly."
"The solution is not great, but it is not bad."
"The scalability has some limitations and quirks to it. I would like to be able to upgrade rather than replace the whole thing."
"The stability depends on who is using the tool, because you only can get as much out of the tool as you put into it. There are a lot of patches for this particular environment, so you have to keep on them. If you lose track of them, then the product is not useful anymore."
"I'd like them to make the product more user-friendly."
"It's not able to communicate with our probes."
"The scalability has some limitations and quirks to it. I would like to be able to upgrade rather than replace the whole thing."
 

Pricing and Cost Advice

"We are using the free version of this solution."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Nagios XI is an expensive solution."
"Licensing costs are reasonable."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"The pricing is high with separate licensing for the product and support."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
"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."
"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
"I would like it to be more scalable with less spend."
"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 price is a little high."
"This product could be cheaper."
