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.

"I can monitor a phone on a desk to very big servers of any company."
"Nagios allows us to configure any device so that we can send pager alerts when people don't have access to emails. It also allows us to schedule downtime and maintenance."
"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it."

Cons

"The product's stability could be even better."

"The Configuration Wizard needs improvement, because not all vendors are present."
"I would like to see support for notification via SMS."
"They need to develop a better integration with a common ticketing system will be great."

"I think some improvements to the Android app would be good."
 

Pricing and Cost Advice

"Nagios XI is an expensive solution."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"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."
"We are using the free version of this solution."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"Nagios XI is open source."
"The pricing is high with separate licensing for the product and support."

"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"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."
"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."
"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."
