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 solution has a lot of plugins and scripts integrated with it."
"They have very accurate and fast support."
"The integration with the alerting software, automated maintenance windows, and the ability to set up templates and groups of checks, as well as customize the checks themselves, are very valuable features."
"Nagios XI is a simple monitoring tool with performance management."
"The most valuable features of Nagios XI are you can customize it based on your use case and requirements, it is flexible and easy to integrate with our systems, and you can customize the solution by adding additional features using code."
"It allows me to quickly see the status of all of my printers, switches, computers, and virtual machines to determine if any system has fallen."
"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."

"We are able to control our business with this all-in-one monitoring tool."
"It provides us with proactive monitoring and is very easy to configure and maintain."
"Stability is where they shine. It has been super stable. We have high-end monitoring for our data centers. We monitor all kinds of metrics in our two data centers. We monitor maybe over 2,500 checks, and the product that has been successful and always alerting us is Pandora."
"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."
 

Cons

"Implementation on Windows was painful."
"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."
"Technical support is very good but is very expensive. It is becoming more and more expensive just like the upgrade."
"Adding new servers and passive checks (which require setting up agents and NRDS) on servers are a little difficult to do properly when employees don't understand the process."
"Nagios XI can improve its GUI for users with a new look."
"Nagios XI can improve its GUI for users with a new look."
"While this solution works, I think that it can be improved in terms of maintenance, support, and price."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"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."
"It would be helpful to include the generation of reports for times that the network was out of service."
"Pandora FMS is relatively new, and the interface with the older version crashes at times."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
"In the future, we may have double the number of devices, and we do not want to have any issues with performance in the data display."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"It would be useful if Pandora FMS included an ISO image (or «software appliance») for each big company that leases virtual private machines (VPS), just like in AWS."
 

Pricing and Cost Advice

"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."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"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."
"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."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"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."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"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."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
