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

"The solution has a lot of plugins and scripts integrated with it."
"An excellent solution that is easy and intuitive to implement."

"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."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it."
"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."
"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."
"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 tool has been of great help because we can manage faster solutions with the problems in our network and it helped us reduce our response time."
"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."
"The network monitoring and configuration within this solution is very good."
 

Cons

"The important separation between Interface and Core to maintain historical plugins and methods generate complexity that makes Nagios unusable for repeat work."
"We'd like to see more integration capabilities."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"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 Configuration Wizard needs improvement, because not all vendors are present."
"Technical support is an area that needs improvement. It is not available 24/7."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"The Configuration Wizard needs improvement, because not all vendors are present."
"A nice feature in the next release would be an automation module to run workflow actions."
"An update to the Android app would be appreciated."
"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
"Pandora could deliver better analytics out of the box."
"A nice feature in the next release would be an automation module to run workflow actions."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"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."
"I think some improvements to the Android app would be good."
 

Pricing and Cost Advice

"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"We are using the free version of this solution."
"Licensing costs are reasonable."
"As it is not an agentless tool, I think it is expensive."
"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."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"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."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"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."
"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 version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
