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 allows my customer to monitor literally thousands of network and computing endpoints (both hardware and software) in real time, including custom derived SNMP polling and traps."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"This is a very good solution and it is simple to use, for any company."
"Our infrastructure is now under monitoring proactively and we don't have to wait for complaints from the customers or internal operation team to inform regarding any issue with the service."
"You can save a lot of time using Nagios monitoring because otherwise you need to check all of your services or system one by one."
"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability."
"It is a very stable solution and the best solution for monitoring any IT infrastructure for all companies."
"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"Thanks to this software and to the work of the support team, we have everything under control."
"The network monitoring and configuration within this solution is very good."
"What I value most about Pandora FMS is the simplicity of working with it."
"The solution has good dashboards and graphics."
"You can configure several types of architecture for high availability or load balancing."
"The official forum is active enough to answer most of the high-end technical questions that you may have."
"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."
 

Cons

"The user interface needs improvement."
"Nagios XI can improve its GUI for users with a new look."
"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 way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough."
"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."
"WebUI should be improved (visual aspect) and should incorporate non-relational databases."
"It can be quite difficult to know which drivers and agents to use when setting up."
"Nagios XI can improve its GUI for users with a new look."
"The product lacks APIs for integration with other systems."
"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 find that this software is resource heavy, and demands a lot of processing capacity."
"A nice feature in the next release would be an automation module to run workflow actions."
"In its versions for Linux, in the beginning, it can be somewhat complicated to configure and implement."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
"Pandora FMS is relatively new, and the interface with the older version crashes at times."
 

Pricing and Cost Advice

"The licensing fees for this solution are approximately $3,000 USD per year."
"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."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Nagios XI is open source."
"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."
"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."
"As it is not an agentless tool, I think it is expensive."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"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."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"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."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
