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 view this product is very good value for money when compared with other commercially provided monitoring solutions."
"Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools."
"It's great for monitoring IT services infrastructure."
"Overall, it's a powerful system."
"Nagios XI is a simple monitoring tool with performance management."
"The most valuable features of Nagios XI are you can customize it based on your use case and requirements. It is flexible and easy to integrate with our systems. You can customize the solution by adding additional features using code."
"The most valuable feature is the monitoring of processes."
"The dashboard allows you to see what's going on in the overall system."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."
"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."
"The network monitoring and configuration within this solution is very good."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
"Thanks to its flexibility, I have been able to adapt the tool to our servers and find out quickly how their console works."
"Pandora FMS is a powerful monitoring system that has enabled us to identify and resolve IT infrastructure problems before they affect critical business processes."
"The support from Pandora FMS is legendary."
 

Cons

"The pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more."
"The web interface is perfectly fit for purpose but isn't up there with the best modern admin panels."
"Nagios XI isn't really good for scaling, in my experience."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"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."
"For some, it may be difficult to deploy."
"There's no convenient way to manage notes as the only way is to manage them through the database."
"WebUI should be improved (visual aspect) and should incorporate non-relational databases."
"In its versions for Linux, in the beginning, it can be somewhat complicated to configure and implement."
"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."
"An update to the Android app would be appreciated."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"The product lacks APIs for integration with other systems and we have issues with monitoring."
"Third-party integration should be improved for some commonly used products."
"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."
"A nice feature in the next release would be an automation module to run workflow actions."
 

Pricing and Cost Advice

"Nagios XI is open source."
"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."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"Nagios XI is an expensive solution."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"The licensing fees for this solution are approximately $3,000 USD per year."
"We are using the free version of this solution."
"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."
"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."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"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."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
