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.

Personalized metrics; simplicity of data
My primary use case for Pandora is monitoring This solution has helped us improve our organization by allowing us to create a lot of metrics on several platforms, including Windows, Linux, and Unix. We then use these Pandora metrics to create an interface. We then pass the interface off to the…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability. We have multiple servers to monitor databases, availability of servers, and ping."
"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"This is a very good solution and it is simple to use, for any company."
"I can monitor a software made in-house to software of bigger companies."
"The solution has a lot of plugins and scripts integrated with it."
"Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"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."
"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."
"The solution is so lightweight that with only 4GB of ram, it allows keeping track of up to two hundred agents from a single console."
"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."
"Thanks to its flexibility, I have been able to adapt the tool to our servers and find out quickly how their console works."
"The official forum is active enough to answer most of the high-end technical questions that you may have."
"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."
 

Cons

"We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios."
"Technical support is an area that needs improvement. It is not available 24/7."
"The interface could be more user-friendly."
"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. But in the end, you learn to live with it."
"Nagios XI can improve network and hardware monitoring, these parameters should be simplified to allow usage for monitoring. Additionally, if there was automatic reporting it would be helpful."
"We'd like to see more integration capabilities."
"The product does not have SAP monitoring."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"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."
"This solution requires proper training to get 100% out of it."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"An update to the Android app would be appreciated."
"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."
"We would like to see improvement in the mainframe integration that this solution is capable of."
"A nice feature in the next release would be an automation module to run workflow actions."
"Third-party integration should be improved for some commonly used products."
 

Pricing and Cost Advice

"The licensing fees for this solution are approximately $3,000 USD per year."
"Licensing costs are reasonable."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"The pricing is high with separate licensing for the product and support."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"Nagios XI is an expensive solution."
"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."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"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."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"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."
