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 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."
"We love Nagios XI due to the fact that JPS Web is very useful."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"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."
"Nagios is an open source monitoring tool for monitoring network services, with easy installation, a user-friendly and configurable interface, and the ability to monitor disk space, CPU utilization, memory usage, host availability, NFS availability and many other things, making it widely used in IT markets."
"The Script Module in Nagios is really easy to use and is really cost efficient."
"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."
"The most valuable feature is the monitoring of processes."
"The official forum is active enough to answer most of the high-end technical questions that you may have."
"Features I have found most valuable with Pandora are the personalized metrics and the simplicity of data."
"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."
"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 administration of the console is very easy. I like that Pandora FMS is interactive and easy to manage."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"Pandora FMS (the Flexible Monitoring System) is an all-in-one package solution, and we can monitor our whole system with Service perspective."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
 

Cons

"While the UI is functional, I have always thought there was room for improvement here."
"While this solution works, I think that it can be improved in terms of maintenance, support, and price."
"They need to develop a better integration with a common ticketing system will be great."
"They need more documentation for the plugins."
"Reporting items needs more improvement and need to be more flexible based on customer needs."
"The product could be optimized to improve the administrative user experience via the Nagios Core Configuration (NCC) GUI module."
"The important separation between Interface and Core to maintain historical plugins and methods generate complexity that makes Nagios unusable for repeat work."
"The user interface needs improvement."
"Pandora FMS is relatively new, and the interface with the older version crashes at times. We have several different operating systems, such as Linux and Windows, and Pandora does not run as well in these."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"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."
"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."
"Pandora could deliver better analytics out of the box."
"I think some improvements to the Android app would be good."
"I think some improvements to the Android app would be good."
 

Pricing and Cost Advice

"Nagios XI is an expensive solution."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"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."
"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."
"Licensing costs are reasonable."
"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."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"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."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"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."
