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 allows us to configure any device so that we can send pager alerts when people don't have access to emails, and it also allows us to schedule downtime and maintenance."
"I really found Nagios a perfect fit for us and a good product to work with."
"Nagios XI is an outstanding network Monitoring tool, which can be tweaked to suit any environment and it is a good solution for business looking for remarkable features at zero cost."
"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, and you can customize the solution by adding additional features using code."
"Since the cost is zero and it can use a fairly cheap server to run on the ROI is nearly immediate."
"I would recommend this solution because it's so powerful with no limitation, especially when using the XI version."
"The solution has a lot of plugins and scripts integrated with it."

"Thanks to this software and to the work of the support team, we have everything under control."
"Network monitoring is fun again with Pandora FMS."
"Pandora FMS is a powerful monitoring system that has enabled us to identify and resolve IT infrastructure problems before they affect critical business processes."
"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. It's also scalable enough to support large environments."
"Features I have found most valuable with Pandora are the personalized metrics and the simplicity of data."
"The most valuable features are auto-discovery and automatic detection of the network topology and network monitoring."
"Thanks to this software and to the work of the support team, we have everything under control."
 

Cons

"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"There's room for improvement in the visibility, and in the ability to extract information."
"If you are monitoring network devices, often it's not scaled for large corporations. Definitely, a minus in that area."
"I would like to see support for notification via SMS."
"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."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"Nagios provides most of the features by default, however to add more services to it, it requires additional plugins which require little effort on administrative end."
"However, it is a bit complex and difficult for a first-time user."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
"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."
"We would like the real-time monitoring of an interface to be improved within this solution."
"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
"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."
 

Pricing and Cost Advice

"Nagios XI is open source."

"The pricing is high with separate licensing for the product and support."

"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"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."
