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 is stable and it's easy to use the monitoring software, which is why we chose this product."
"The solution has a lot of plugins and scripts integrated with it."
"Nagios XI is a simple monitoring tool with performance management."
"Nagios XI allows my customer to monitor literally thousands of network and computing endpoints (both hardware and software) in real time, including custom derived SNMP polling and traps."
"Nagios is great for verify quality and quantity in a datacenter."
"It has a lot of flexibility for customization and a wide range of metrics."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"This solution has screens that are easy to understand and provide a wealth of information."
"We are able to control our business with this all-in-one monitoring tool."
"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."
"Thanks to this software and to the work of the support team, we have everything under control."
"Pandora FMS (the Flexible Monitoring System) is an all-in-one package solution, and we can monitor our whole system with Service perspective."
"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."
"Thanks to its flexibility, I have been able to adapt the tool to our servers and find out quickly how their console works."
 

Cons

"The reporting part should be made simpler. While we can obtain all the reports we need, we always have to create work-arounds to get them."
"Nagios XI can improve its GUI for users with a new look."
"Reporting items needs more improvement and need to be more flexible based on customer needs."
"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"Technical support is very good but is very expensive. It is becoming more and more expensive just like the upgrade."
"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."
"They need to develop a better integration with a common ticketing system will be great."
"We are implementing our hybrid cloud strategy, and it will most likely not be suitable for monitoring our public cloud assets."
"I would like for the solution to be faster and have a better tolerance between parallel servers for Pandora and Pest Control."
"An update to the Android app would be appreciated."
"They can also do more refinement in end-user usability because not everyone is strong technically, and people who aren't strong technically might be averse to the product, even though it has come a long way."
"We would like the real-time monitoring of an interface to be improved within this solution."
"The price for Pandora FMS is expensive."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"Improvements are needed for server and network discovery, including service-based discovery."
"It would be helpful to include the generation of reports for times that the network was out of service."
 

Pricing and Cost Advice

"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"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."
"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."
"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."
"We are using the free version of this solution."
"Licensing costs are reasonable."
"Nagios XI is open source."
"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."

"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."
"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."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
