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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"An excellent solution that is easy and intuitive to implement."
"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"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."
"The installation is no problem. I've installed Nagios several times."
"The Script Module in Nagios is really easy to use and is really cost efficient."
"We love Nagios XI due to the fact that JPS Web is very useful."
"The solution has a lot of plugins and scripts integrated with it."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"Thanks to this software and to the work of the support team, we have everything under control."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
"The most valuable feature is that it is an all-in-one monitoring system."
"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."
"The network monitoring and configuration within this solution is very good."
"The most valuable features are auto-discovery and automatic detection of the network topology and network monitoring."
"We are able to control our business with this all-in-one monitoring tool."
"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."
 

Cons

"They need more documentation for the plugins."
"Nagios XI can improve network and hardware monitoring, these parameters should be simplified to allow usage for monitoring. Additionally, if there was automatic reporting it would be helpful."
"It can be quite difficult to know which drivers and agents to use when setting up."
"Open-source software is usually not user-friendly."
"The product could be optimized to improve the administrative user experience via the Nagios Core Configuration (NCC) GUI module."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"From an alerting point of view, some graphics and metrics don't work properly with Nagios XI as they do with Checkmk."
"An update to the Android app would be appreciated."
"It would be helpful to include the generation of reports for times that the network was out of service."
"Third-party integration should be improved for some commonly used products."
"I would like for the solution to be faster and have a better tolerance between parallel servers for Pandora and Pest Control."
"We would like the real-time monitoring of an interface to be improved within this solution."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
 

Pricing and Cost Advice

"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"As it is not an agentless tool, I think it is expensive."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"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."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"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."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"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."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"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."
"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."
"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."
