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

"It is an open-source platform with valuable features for performance and stability."
"Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"All of them, but mainly: Highly-efficient server performance monitoring engine Configuration wizards Infrastructure management Configuration snapshot."
"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"Nagios is an open source monitoring tool for monitoring network services, with easy installation, a user-friendly and configurable interface, and the ability to monitor disk space, CPU utilization, memory usage, host availability, NFS availability and many other things, making it widely used in IT markets."
"I would recommend this solution because it's so powerful with no limitation, especially when using the XI version."
"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."
"Thanks to this software and to the work of the support team, we have everything under control."
"The most valuable features are auto-discovery and automatic detection of the network topology and network monitoring."
"The administration of the console is very easy. I like that Pandora FMS is interactive and easy to manage."
"Each of these points I think represents the keys as to why this software works in my jewelry stores, as it gives me greater control over all of the devices, the best performance, and I can interpret the data easily and much faster, with excellent results."
"This solution has screens that are easy to understand and provide a wealth of information."
"Network monitoring is fun again with Pandora FMS."
"Pandora FMS (the Flexible Monitoring System) is an all-in-one package solution, and we can monitor our whole system with Service perspective."
"What I value most about Pandora FMS is the simplicity of working with it."
 

Cons

"Technical support is very good but is very expensive. It is becoming more and more expensive just like the upgrade."
"Nagios XI doesn't provide scripting. For example, if we have built up multiple IPX tunnels from a base location to a data center location and want to monitor or trigger an alert if the tunnel goes down, Nagios XI does not automatically send alerts notifying us that the tunnel is down."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"We're still experiencing stability issues with regards to collecting performance graphs."
"While the UI is functional, I have always thought there was room for improvement here."
"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 user interface needs improvement."
"There's room for improvement in the visibility, and in the ability to extract information."
"It would be helpful to include the generation of reports for times that the network was out of service."
"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."
"It would be helpful to include the generation of reports for times that the network was out of service."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
"A nice feature in the next release would be an automation module to run workflow actions."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"Third-party integration should be improved for some commonly used products such as Universal CMDB."
 

Pricing and Cost Advice

"The licensing fees for this solution are approximately $3,000 USD per year."
"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."
"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."
"As it is not an agentless tool, I think it is expensive."
"The pricing is high with separate licensing for the product and support."
"We are using the free version of this solution."
"Nagios XI is open source."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"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."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"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."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
