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

"Nagios allows us to configure any device so that we can send pager alerts when people don't have access to emails. It also allows us to schedule downtime and maintenance."
"It is an open-source platform with valuable features for performance and stability."
"The dashboard allows you to see what's going on in the overall system."
"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 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."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"The solution has a lot of plugins and scripts integrated with it."
"The most useful aspect of this solution is the ability to customize it for the client agent."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"We are able to control our business with this all-in-one monitoring tool."
"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."
"Thanks to its flexibility, I have been able to adapt the tool to our servers and find out quickly how their console works."
"Pandora's architecture is interesting. It's open so you can easily extend and enhance it. It's simpler to customize Pandora compared to other solutions. It's also scalable enough to support large environments."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
"The most valuable features are auto-discovery and automatic detection of the network topology and network monitoring."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
 

Cons

"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."
"The reporting structure could be more streamlined."
"It can be quite difficult to know which drivers and agents to use when setting up."
"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."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
"Open-source software is usually not user-friendly."
"We would like the real-time monitoring of an interface to be improved within this solution."
"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 FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
"Third-party integration should be improved for some commonly used products."
"Pandora FMS is relatively new, and the interface with the older version crashes at times. We have several different operating systems, such as Linux and Windows, and Pandora does not run as well in these."
"I think some improvements to the Android app would be good."
"It would be useful if Pandora FMS included an ISO image (or «software appliance») for each big company that leases virtual private machines (VPS), just like in AWS."
"Improvements are needed for server and network discovery, including service-based discovery."
 

Pricing and Cost Advice

"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."
"Nagios XI is an expensive solution."
"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."
"We are using the free version of this solution."
"The pricing is high with separate licensing for the product and support."
"The licensing fees for this solution are approximately $3,000 USD per year."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"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."
"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."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
