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

"Simplicity of configuration; I can set up configuration of 100 devices with about 10 services in one to two days."
"The solution's most valuable feature is its simplicity."
"They have very accurate and fast support."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"Since the cost is zero and it can use a fairly cheap server to run on the ROI is nearly immediate."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"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."
"Nagios XI helped me to draw the network and check for system failures."
"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 FMS (the Flexible Monitoring System) is an all-in-one package solution, and we can monitor our whole system with Service perspective."
"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."
"Thanks to Pandora FMS, we've been able to adapt to every new monitoring challenge over the past seven years."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
"Pandora FMS is a powerful monitoring system that has enabled us to identify and resolve IT infrastructure problems before they affect critical business processes."
"Thanks to this software and to the work of the support team, we have everything under control."
 

Cons

"I would like to see support for notification via SMS."
"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 way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough."
"They need to develop a better integration with a common ticketing system will be great."
"There's room for improvement in the visibility, and in the ability to extract information."
"The pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"Technical support is an area that needs improvement. It is not available 24/7."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"Improvements are needed for server and network discovery, including service-based discovery."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"The product lacks APIs for integration with other systems and we have issues with monitoring."
"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."
"The price for Pandora FMS is expensive."
"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 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."
 

Pricing and Cost Advice

"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."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
