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

"In my experience with Nagios, I've found that the most valuable features are the scalability and extensibility through using scripts."
"The solution has a lot of plugins and scripts integrated with it."
"Overall, it's a powerful system."
"Nagios is great for verify quality and quantity in a datacenter."
"All of them, but mainly: Highly-efficient server performance monitoring engine Configuration wizards Infrastructure management Configuration snapshot."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"I can monitor a software made in-house to software of bigger companies."
"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."
"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."
"Thanks to this software and to the work of the support team, we have everything under control."
"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."
"Features I have found most valuable with Pandora are the personalized metrics and the simplicity of data."
"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 Pandora FMS, we've been able to adapt to every new monitoring challenge over the past seven years."
"The network monitoring and configuration within this solution is very good."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
 

Cons

"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"For some, it may be difficult to deploy."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"Technical support is an area that needs improvement. It is not available 24/7."
"Initially, we encountered problems during the setup as some errors were noted due to a few prerequisites not being fulfilled and having some configuration files to edit and plugins to add."
"We'd like to see more integration capabilities."
"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."
"However, it is a bit complex and difficult for a first-time user."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"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."
"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."
"We would like the real-time monitoring of an interface to be improved within this solution."
"Third-party integration should be improved for some commonly used products such as Universal CMDB."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"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."
 

Pricing and Cost Advice

"We are using the free version of this solution."
"Licensing costs are reasonable."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"The licensing fees for this solution are approximately $3,000 USD per year."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"As it is not an agentless tool, I think it is expensive."
"Nagios XI is open source."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"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."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
