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's great for monitoring IT services infrastructure."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"Nagios XI is stable."
"Since this is an open source technology, if we are capable of writing the plugins in any scripting language, this product allows us to monitor anything we want."
"The integration with the alerting software, automated maintenance windows, and the ability to set up templates and groups of checks, as well as customize the checks themselves, are very valuable features."
"The most useful aspect of this solution is the ability to customize it for the client agent."
"An excellent solution that is easy and intuitive to implement."
"The dashboard allows you to see what's going on in the overall system."
"The support from Pandora FMS is legendary."
"This tool has been of great help because we can manage faster solutions with the problems in our network and it helped us reduce our response time."
"This solution has screens that are easy to understand and provide a wealth of information."
"It is easy to create your own custom modules if you just know a little bit of scripting. If you have unique requirements, you can just make your own modules. You can even grab checks from other vendors. There are open-source checks for various things such as SMTP, etc. There is a long list of different ones from Nagios. You can just use them, and within seconds, you get yourself a check that is monitoring whatever you need. It is really flexible. I guess that's why they call it Pandora Flexible Monitoring System (FMS). It is reliable. It does the job, and it alerts. It is also surprisingly feature-rich. Our network guy just recently asked about a particular protocol to monitor the bandwidth on the network, which is not a common protocol. When I looked it up, and I found that they cover it. It is very mature for a not-so-known product."
"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."
"Thanks to this software and to the work of the support team, we have everything under control."
"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."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
 

Cons

"The tool's AI model needs to be fixed."
"Backup mechanisms and some kind of templating system for dashboards are needed."
"Its simple deployment but complexity comes once you have to import more plugins."
"While the UI is functional, I have always thought there was room for improvement here."
"Technical support is an area that needs improvement. It is not available 24/7."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
"Initially, we encountered problems during the setup as some errors were noted due to a few prerequisites not being fulfilled and having some configuration files to edit and plugins to add."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"The price for Pandora FMS is expensive."
"In its versions for Linux, in the beginning, it can be somewhat complicated to configure and implement."
"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
"Pandora FMS is relatively new, and the interface with the older version crashes at times. We have several different operating systems, such as Linux and Windows, and Pandora does not run as well in these."
"We would like to see improvement in the mainframe integration that this solution is capable of."
"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."
"It would be helpful to include the generation of reports for times that the network was out of service."
"I find that this software is resource heavy, and demands a lot of processing capacity."
 

Pricing and Cost Advice

"Licensing costs are reasonable."
"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."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"The pricing is high with separate licensing for the product and support."
"As it is not an agentless tool, I think it is expensive."
"Nagios XI is open source."
"Nagios XI is an expensive solution."
"The licensing fees for this solution are approximately $3,000 USD per year."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"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 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."
"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 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."
