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

"The most valuable feature is the monitoring of processes."
"Nagios is the best monitoring tool that I have ever worked on."
"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."
"Nagios is great for verify quality and quantity in a datacenter."
"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."
"The overall performance of the product is superb."
"The solution's most valuable feature is its simplicity."
"It is a very stable solution and the best solution for monitoring any IT infrastructure for all companies."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
"The administration of the console is very easy. I like that Pandora FMS is interactive and easy to manage."
"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."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"Pandora FMS is an all-in-one solution that is cost-efficient."
"Pandora FMS is a powerful monitoring system that has enabled us to identify and resolve IT infrastructure problems before they affect critical business processes."
"Each of these points I think represents the keys as to why this software works in my jewelry stores, as it gives me greater control over all of the devices, the best performance, and I can interpret the data easily and much faster, with excellent results."
"The solution has good dashboards and graphics."
 

Cons

"We are implementing our hybrid cloud strategy, and it will most likely not be suitable for monitoring our public cloud assets."
"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."
"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."
"Nagios XI isn't really good for scaling, in my experience."
"Backup mechanisms and some kind of templating system for dashboards are needed."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"Improve the documentation, examples, and best practices, therefore users can understand how to do things."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"The product lacks APIs for integration with other systems and we have issues with monitoring."
"Improvements are needed for server and network discovery, including service-based discovery."
"This solution requires proper training to get 100% out of it."
"A nice feature in the next release would be an automation module to run workflow actions."
"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
"I think some improvements to the Android app would be good."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"We would like the real-time monitoring of an interface to be improved within this solution."
 

Pricing and Cost Advice

"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."
"The pricing is high with separate licensing for the product and support."
"Licensing costs are reasonable."
"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."
"Nagios XI is open source."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"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."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"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 version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
