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 has good scalability."
"I really found Nagios a perfect fit for us and a good product to work with."
"Nagios XI is a simple monitoring tool with performance management and everything a standard monitoring tool provides."
"It provides an easy and powerful solution to network monitoring so I can pay attention to other concerns."
"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it. That's very useful."
"The integration with the alerting software, automated maintenance windows, and the ability to set up templates and groups of checks, as well as customize the checks themselves, are very valuable features."
"Nagios is great for verify quality and quantity in a datacenter."
"The solution has a lot of plugins and scripts integrated with it."
"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."
"The solution has good dashboards and graphics."
"The support from Pandora FMS is legendary."
"The solution has good dashboards and graphics."
"Thanks to its flexibility, I have been able to adapt the tool to our servers and find out quickly how their console works."
"Thanks to Pandora FMS, we've been able to adapt to every new monitoring challenge over the past seven years."
"Pandora FMS is a powerful monitoring system that has enabled us to identify and resolve IT infrastructure problems before they affect critical business processes."
"We are consultants and thanks to Pandora can detect a lot of disasters that other companies can't, and we can offer high availability of the system to the client."
 

Cons

"The interface could be more user-friendly."
"We are implementing our hybrid cloud strategy, and it will most likely not be suitable for monitoring our public cloud assets."
"The GUI could be improved."
"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."
"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 GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"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."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"An update to the Android app would be appreciated."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"We would like to see improvement in the mainframe integration that this solution is capable of."
"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."
"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 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."
"A nice feature in the next release would be an automation module to run workflow actions."
 

Pricing and Cost Advice

"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 XI is open source."
"Licensing costs are reasonable."
"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."
"The pricing is high with separate licensing for the product and support."
"Nagios XI is an expensive solution."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"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."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"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."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"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."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
