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:

"Overall, it's a powerful system."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"The most valuable features of Nagios XI are you can customize it based on your use case and requirements. It is flexible and easy to integrate with our systems. You can customize the solution by adding additional features using code."
"Nagios is the best monitoring tool that I have ever worked on."
"It has a wide variety of plugins in existence, but when there's no plugin available it is quite simple to integrate one's own programs and scripts."
"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."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
"Network monitoring is fun again with Pandora FMS."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."

"You can configure several types of architecture for high availability or load balancing."

Cons

"While the UI is functional, I have always thought there was room for improvement here."
"The installation and monitoring need improvement."
"The product does not have SAP monitoring."
"Nagios XI doesn't provide scripting. For example, if we have built up multiple IPX tunnels from a base location to a data center location and want to monitor or trigger an alert if the tunnel goes down, Nagios XI does not automatically send alerts notifying us that the tunnel is down."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"The installation can get very difficult depending on what Linux flavour you are using."
"Technical support is an area that needs improvement. It is not available 24/7."
"A nice feature in the next release would be an automation module to run workflow actions."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"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 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."
"An update to the Android app would be appreciated."
"The price for Pandora FMS is expensive."
"Improvements are needed for server and network discovery, including service-based discovery."
"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."
 

Pricing and Cost Advice

"As it is not an agentless tool, I think it is expensive."
"The pricing is high with separate licensing for the product and support."
"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."
"The licensing fees for this solution are approximately $3,000 USD per year."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Licensing costs are reasonable."
"Nagios XI is open source."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"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."
"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."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"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."
