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 is an open source monitoring tool for monitoring network services, with easy installation, a user-friendly and configurable interface, and the ability to monitor disk space, CPU utilization, memory usage, host availability, NFS availability and many other things, making it widely used in IT markets."
"If you are a mid-sied company with an eye on expansion, this solution is very good."
"Nagios is the best monitoring tool that I have ever worked on."
"This is a very good solution and it is simple to use, for any company."
"Nagios is my favourite open source monitoring system."
"The solution is pretty stable."
"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."
"It is a very stable solution and the best solution for monitoring any IT infrastructure for all companies."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"Thanks to Pandora FMS, we've been able to adapt to every new monitoring challenge over the past seven years."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
"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."
"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 is so lightweight that with only 4GB of ram, it allows keeping track of up to two hundred agents from a single console."
 

Cons

"Implementation on Windows was painful."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"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."
"Backup mechanisms and some kind of templating system for dashboards are needed."
"While the UI is functional, I have always thought there was room for improvement here."
"If you are monitoring network devices, often it's not scaled for large corporations. Definitely, a minus in that area."
"Business services monitoring is still really basic."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"The product lacks APIs for integration with other systems and we have issues with monitoring."
"I think some improvements to the Android app would be good."
"We would like to see improvement in the mainframe integration that this solution is capable of."
"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 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."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"Third-party integration should be improved for some commonly used products such as Universal CMDB."
 

Pricing and Cost Advice

"The pricing is high with separate licensing for the product and support."
"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."
"Nagios XI is an expensive solution."
"We are using the free version of this solution."
"Nagios XI is open source."
"Licensing costs are reasonable."
"The licensing fees for this solution are approximately $3,000 USD per year."
"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."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"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."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
