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.

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."
"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"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 technical support is good."
"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability. We have multiple servers to monitor databases, availability of servers, and ping."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it. That's very useful."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"The network monitoring and configuration within this solution is very good."
"We are able to control our business with this all-in-one monitoring tool."
"You can configure several types of architecture for high availability or load balancing."
"It provides us with proactive monitoring and is very easy to configure and maintain."
"The solution has good dashboards and graphics."
"The solution is so lightweight that with only 4GB of ram, it allows keeping track of up to two hundred agents from a single console."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
"The most valuable feature is that it is an all-in-one monitoring system."
 

Cons

"Nagios XI can improve network and hardware monitoring, these parameters should be simplified to allow usage for monitoring. Additionally, if there was automatic reporting it would be helpful."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"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."
"Open-source software is usually not user-friendly."
"The GUI could be improved."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"It can be quite difficult to know which drivers and agents to use when setting up."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"Pandora could deliver better analytics out of the box. You can work around these limitations with the help of other tools like Grafana. The shortcomings are mostly on the graphical side. The built-in report generators are a bit limited in some areas."
"A nice feature in the next release would be an automation module to run workflow actions."
"Third-party integration should be improved for some commonly used products."
"The price for Pandora FMS is expensive."
"I would like for the solution to be faster and have a better tolerance between parallel servers for Pandora and Pest Control."
"An update to the Android app would be appreciated."
"In the future, we may have double the number of devices, and we do not want to have any issues with performance in the data display."
"I think some improvements to the Android app would be good."
 

Pricing and Cost Advice

"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"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."
"Nagios XI is an expensive solution."
"Licensing costs are reasonable."
"The licensing fees for this solution are approximately $3,000 USD per year."
"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."
"We are using the free version of this solution."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"My rule of thumb would be that if you need more than thirty agents, and you lack an automation tool such as Chef or Puppet, you will save a lot of time and money going to the Enterprise edition."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
