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 product allows comprehensive monitoring of your environment, from basic monitoring of your servers health to more complex tasks like AD, database, and, to some extent, application-level monitoring."
"Nagios is my favourite open source monitoring system."
"The alerting system is very effective."
"Nagios is the best monitoring tool that I have ever worked on."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"It is a very stable solution and the best solution for monitoring any IT infrastructure for all companies."
"The solution is pretty stable."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"The network monitoring and configuration within this solution is very good."
"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 solution has good dashboards and graphics."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
"Thanks to Pandora FMS, we've been able to adapt to every new monitoring challenge over the past seven years."
"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."
"It provides us with proactive monitoring and is very easy to configure and maintain."
"Features I have found most valuable with Pandora are the personalized metrics and the simplicity of data."
 

Cons

"Business services monitoring is still really basic."
"We'd like to see more integration capabilities."
"This solution would be improved with the inclusion of additional services. Monitoring streaming services is an example of something that is not currently supported, so in order to handle this, I would have to write a script."
"Open-source software is usually not user-friendly."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"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."
"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."
"This solution requires proper training to get 100% out of it."
"An update to the Android app would be appreciated."
"An update to the Android app would be appreciated."
"Third-party integration should be improved for some commonly used products such as Universal CMDB."
"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 think some improvements to the Android app would be good."
"Pandora could deliver better analytics out of the box."
"It would be helpful to include the generation of reports for times that the network was out of service."
 

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 licensing fees for this solution are approximately $3,000 USD per year."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"The pricing is high with separate licensing for the product and support."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Nagios XI is an expensive solution."
"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."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"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."
"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."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"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."
