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

"You want to monitor a specific metric that nobody else has? You can do it even with the most basic of scripting skills, and you can always share it with the vast community of Nagios Exchange."
"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."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"Simplicity of configuration; I can set up configuration of 100 devices with about 10 services in one to two days."
"The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need."
"The most useful aspect of this solution is the ability to customize it for the client agent."
"It's very easy to install it and manage it with Nagios XI's interface."
"They have very accurate and fast support."
"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."
"Network monitoring is fun again with Pandora FMS."
"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."
"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."
"The most valuable feature is that it is an all-in-one monitoring system."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"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."
 

Cons

"I would like to see support for notification via SMS."
"Its simple deployment but complexity comes once you have to import more plugins."
"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 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."
"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."
"We're still experiencing stability issues with regards to collecting performance graphs."
"However, it is a bit complex and difficult for a first-time user."
"A nice feature in the next release would be an automation module to run workflow actions."
"I think some improvements to the Android app would be good."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
"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."
"I would like for the solution to be faster and have a better tolerance between parallel servers for Pandora and Pest Control."
"Improvements are needed for server and network discovery, including service-based discovery."
"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."
 

Pricing and Cost Advice

"Nagios XI is open source."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"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 licensing fees for this solution are approximately $3,000 USD per year."
"We are using the free version of this solution."
"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 high with separate licensing for the product and support."
"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."
"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."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
