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 dashboard allows you to see what's going on in the overall system."
"It's great for monitoring IT services infrastructure."
"The technical support is good."
"Nagios XI helped me to draw the network and check for system failures."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"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."
"Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools."
"The most valuable feature is the monitoring of processes."
"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 features are auto-discovery and automatic detection of the network topology and network monitoring."
"We are able to control our business with this all-in-one monitoring tool."
"Thanks to this software and to the work of the support team, we have everything under control."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"The official forum is active enough to answer most of the high-end technical questions that you may have."
"The administration of the console is very easy. I like that Pandora FMS is interactive and easy to manage."
"You can configure several types of architecture for high availability or load balancing."
 

Cons

"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."
"From an alerting point of view, some graphics and metrics don't work properly with Nagios XI as they do with Checkmk."
"I would like to see support for notification via SMS."
"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"The reporting structure could be more streamlined."
"We'd like to see more integration capabilities."
"The product does not have SAP monitoring."
"It would be helpful to include the generation of reports for times that the network was out of service."
"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."
"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."
"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."
"I would like for the solution to be faster and have a better tolerance between parallel servers for Pandora and Pest Control."
"A nice feature in the next release would be an automation module to run workflow actions."
"The product lacks APIs for integration with other systems."
"I find that this software is resource heavy, and demands a lot of processing capacity."
 

Pricing and Cost Advice

"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"The licensing fees for this solution are approximately $3,000 USD per year."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"Nagios XI is an expensive solution."
"As it is not an agentless tool, I think it is expensive."
"The pricing is high with separate licensing for the product and support."
"Nagios XI is open source."
"Licensing costs are reasonable."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"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."
"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."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
