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.

Flexible device polling times and extensible modules are key features for me
There are lots of reasons why I'm using it. The installer itself is basically something that can be used as a no-questions-asked type of installer. I can use it with automation tools like Chef and Puppet. I don't have to answer some random questions. I can worry about all that stuff later on in the configuration. It allows for variable polling times of devices on the network. Because it's all in text, in general, that obviously makes it easier from the automation perspective as well, to modify configuration on the fly, using Puppet and those kind of tools. It does have different modules, so you can extend the solution as you need it, or get as little as you need in the beginning, so you don't have to buy a full set of modules. You just buy what you need and expand later on.

Quotes from Members

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

Pros

"Nagios XI is a simple monitoring tool with performance management."
"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 great for monitoring IT services infrastructure."
"It is an open-source platform with valuable features for performance and stability."
"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."
"The solution's most valuable feature is its simplicity."
"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"It allows for variable polling times of devices on the network. Because it's all in text, in general, that obviously makes it easier from the automation perspective as well, to modify configuration on the fly, using Puppet and those kind of tools."
"The big thing is the event management engine, which is really, really nice to use, and it comes at a reasonable price, unlike some of the competitors like Netcool from IBM. Those kinds of tools are hugely expensive and they come as resource-heavy types of solutions. This obviously doesn't require as much hardware, but it does offer similar benefits where you can manage all the events."
"In my case, I prefer to only poll interfaces that have descriptions, and the ones that don't have descriptions, I don't really want to know about them. It does allow for all these bits and pieces and adjustments, and fine tuning to get it to a point where it works for my needs."
"It does have different modules, so you can extend the solution as you need it, or get as little as you need in the beginning, so you don't have to buy a full set of modules. You just buy what you need and expand later on."
"The installer itself is basically something that can be used as a no-questions-asked type of installer. I can use it with automation tools like Chef and Puppet. I don't have to answer some random questions. I can worry about all that stuff later on in the configuration."
 

Cons

"The product's stability could be even better."
"They need more documentation for the plugins."
"The product does not have SAP monitoring."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"The installation and monitoring need improvement."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"These kinds of solutions are more node- or device-based solutions. It would be nice in the future if they could be more data-oriented, so it would be easier for me to pull different stats based on ad-hoc requirements; but in a big, centralized database where I can pull specific things, and mix and match the way I want to."
 

Pricing and Cost Advice

"As it is not an agentless tool, I think it is expensive."
"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."
"Nagios XI is an expensive solution."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"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."

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…

Questions from the Community

What do you like most about Nagios XI?
It is an open-source platform with valuable features for performance and stability.
What needs improvement with Nagios XI?
The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this. Also, there is room for improvement in the interface.
