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 XI is stable."
"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 installation is no problem. I've installed Nagios several times."
"The dashboard allows you to see what's going on in the overall system."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"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."
"The solution is pretty stable."
"What I value most about Pandora FMS is the simplicity of working with it."
"Features I have found most valuable with Pandora are the personalized metrics and the simplicity of data."
"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. It's also scalable enough to support large environments."
"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 solution has good dashboards and graphics."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
 

Cons

"Adding new servers and passive checks (which require setting up agents and NRDS) on servers are a little difficult to do properly when employees don't understand the process."
"Technical support is an area that needs improvement. It is not available 24/7."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"While this solution works, I think that it can be improved in terms of maintenance, support, and price."
"I think that the community needs to concentrate development to get a standard GUI (Adagios is a side project) and gives the user a better notification system."
"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box."
"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."
"The user interface needs improvement."
"The product lacks APIs for integration with other systems."
"Improvements are needed for server and network discovery, including service-based discovery."
"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."
"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."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"A nice feature in the next release would be an automation module to run workflow actions."
 

Pricing and Cost Advice

"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"The pricing is high with separate licensing for the product and support."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"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."
"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."
"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."
"Nagios XI is an expensive solution."
"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."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"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."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"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."
