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.

The open architecture is easy to extend and enhance
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. They could improve their management console's ability to monitor large environments could be improved. For example, SNMP management is only partially integrated into the management console.

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, and it also allows us to schedule downtime and maintenance."
"It has a wide variety of plugins in existence, but when there's no plugin available it is quite simple to integrate one's own programs and scripts."
"The solution's most valuable feature is its simplicity."
"The most valuable feature is the monitoring of processes."
"I can monitor a software made in-house to software of bigger companies."
"Nagios XI is a simple monitoring tool with performance management."
"In my view this product is very good value for money when compared with other commercially provided monitoring solutions."
"Nagios is the best monitoring tool that I have ever worked on."
"Stability is where they shine. It has been super stable. We have high-end monitoring for our data centers. We monitor all kinds of metrics in our two data centers. We monitor maybe over 2,500 checks, and the product that has been successful and always alerting us is Pandora."
"Thanks to this software and to the work of the support team, we have everything under control."
"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 has good dashboards and graphics."
"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."
"The support from Pandora FMS is legendary."
"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, and it's also scalable enough to support large environments."
"This solution has screens that are easy to understand and provide a wealth of information."
 

Cons

"While the UI is functional, I have always thought there was room for improvement here."
"The reporting structure could be more streamlined."
"Nagios provides most of the features by default, however to add more services to it, it requires additional plugins which require little effort on administrative end."
"There are stability issues if you have a large number of hosts and services."
"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."
"However, it is a bit complex and difficult for a first-time user."
"It's in need of more standard plug-ins."
"Backup mechanisms and some kind of templating system for dashboards are needed."
"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
"We would like the real-time monitoring of an interface to be improved within this solution."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"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."
"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 think some improvements to the Android app would be good."
 

Pricing and Cost Advice

"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."
"As it is not an agentless tool, I think it is expensive."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Licensing costs are reasonable."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"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."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"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."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
