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

"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."
"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 stable and it's easy to use the monitoring software, which is why we chose this product."
"Nagios XI is stable."
"It provides an easy and powerful solution to network monitoring so I can pay attention to other concerns."
"Nagios has good scalability."
"I really found Nagios a perfect fit for us and a good product to work with."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"Network monitoring is fun again with Pandora FMS."
"The official forum is active enough to answer most of the high-end technical questions that you may have."
"We are consultants and thanks to Pandora can detect a lot of disasters that other companies can't, and we can offer high availability of the system to the client."
"In comparison with most monitoring software, this software is incredibly easy to use."
"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."
"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."
"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."
 

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."
"They need more documentation for the plugins."
"Nagios XI can improve its GUI for users with a new look."
"The web interface is perfectly fit for purpose but isn't up there with the best modern admin panels."
"From an alerting point of view, some graphics and metrics don't work properly with Nagios XI as they do with Checkmk."
"The Configuration Wizard needs improvement, because not all vendors are present."
"Nagios needs to improve their incident manager. Currently, it isn't good for ITIL in my opinion."
"It's in need of more standard plug-ins."
"A nice feature in the next release would be an automation module to run workflow actions."
"This solution requires proper training to get 100% out of it."
"We would like to see improvement in the mainframe integration that this solution is capable of."
"In its versions for Linux, in the beginning, it can be somewhat complicated to configure and implement."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"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."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
"We would like the real-time monitoring of an interface to be improved within this solution."
 

Pricing and Cost Advice

"We are using the free version of this solution."
"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."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"Nagios XI is an expensive solution."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"As it is not an agentless tool, I think it is expensive."
"Nagios XI is open source."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"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."
"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."
"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."
"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."
