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 ability to set up templates and groups of checks, as well as customize the checks themselves."
"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."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"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 simplifies our setup and reduces the time spent configuring monitoring tools."
"The dashboard allows you to see what's going on in the overall system."
"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
"Thanks to its flexibility, I have been able to adapt the tool to our servers and find out quickly how their console works."
"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."
"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."
"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."
"The solution has good dashboards and graphics."
"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."
 

Cons

"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"Open-source software is usually not user-friendly."
"The reporting part should be made simpler. While we can obtain all the reports we need, we always have to create work-arounds to get them."
"The product does not have SAP monitoring."
"Nagios XI can improve its GUI for users with a new look."
"The tool's AI model needs to be fixed."
"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."
"An update to the Android app would be appreciated."
"Their support is good, but it is just online communication. It would be great to be able to just call someone and talk to them instead of always writing. It works well for me because I am a decent communicator in email, but some people might find it difficult to describe in a written fashion and communicate with them that way. There is a learning curve to the interface, but once you get used to it, it is actually very powerful. They have a lot of options, but people struggle with the interface. They've improved it though, and it is getting better. They need to keep improving the learning curve to help buy-in. I'm the guy that manages it, so I'm comfortable with it. They can refine the upgrade agents to be easier. They can also do more refinement in end-user usability because not everyone is strong technically, and people who aren't strong technically might be averse to the product, even though it has come a long way. It has a complete GUI and everything."
"Improvements are needed for server and network discovery, including service-based discovery."
"We would like to see improvement in the mainframe integration that this solution is capable of."
"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."
"This solution requires proper training to get 100% out of it."
"A nice feature in the next release would be an automation module to run workflow actions."
"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
 

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 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 licensing fees for this solution are approximately $3,000 USD per year."
"As it is not an agentless tool, I think it is expensive."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"Nagios XI is open source."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"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."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"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."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
