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

"The most valuable feature is the monitoring of processes."
"I can monitor a phone on a desk to very big servers of any company."
"Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools."
"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need."
"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."
"The solution is pretty stable."
"The technical support is good."
"It provides us with proactive monitoring and is very easy to configure and maintain."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"It allows me to quickly see the status of all of my printers, switches, computers, and virtual machines to determine if any system has fallen."
"What I value most about Pandora FMS is the simplicity of working with it."
"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 most valuable features are auto-discovery and automatic detection of the network topology and network monitoring."
"The network monitoring and configuration within this solution is very good."
"It is easy to create your own custom modules if you just know a little bit of scripting. If you have unique requirements, you can just make your own modules. You can even grab checks from other vendors. There are open-source checks for various things such as SMTP, etc. There is a long list of different ones from Nagios. You can just use them, and within seconds, you get yourself a check that is monitoring whatever you need. It is really flexible. I guess that's why they call it Pandora Flexible Monitoring System (FMS). It is reliable. It does the job, and it alerts. It is also surprisingly feature-rich. Our network guy just recently asked about a particular protocol to monitor the bandwidth on the network, which is not a common protocol. When I looked it up, and I found that they cover it. It is very mature for a not-so-known product."
 

Cons

"The product could be optimized to improve the administrative user experience via the Nagios Core Configuration (NCC) GUI module."
"The installation and monitoring need improvement."
"Open-source software is usually not user-friendly."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"The product does not have SAP monitoring."
"The reporting structure could be more streamlined."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"The GUI could be improved."
"I think some improvements to the Android app would be good."
"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."
"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."
"The price for Pandora FMS is expensive."
"The product lacks APIs for integration with other systems."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
"We would like the real-time monitoring of an interface to be improved within this solution."
"Improvements are needed for server and network discovery, including service-based discovery."
 

Pricing and Cost Advice

"The pricing is high with separate licensing for the product and support."
"Nagios XI is an expensive solution."
"Nagios XI is open source."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"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."
"Licensing costs are reasonable."
"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 Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"You have to pay for the number of agents and models that you are monitoring. I would rate the cost at three with one being the most expensive and five being the cheapest."
