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 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."
"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."
"The most valuable feature of Nagios XI is customization. We can customize based on our requirements. We can do modifications and implement a lot of scripts. Additionally, it is easy to use."
"It is an open-source platform with valuable features for performance and stability."
"You can save a lot of time using Nagios monitoring because otherwise you need to check all of your services or system one by one."
"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"This is a very good solution and it is simple to use, for any company."
"I really found Nagios a perfect fit for us and a good product to work with."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"The support from Pandora FMS is legendary."
"The support is excellent for this product; their response time is very fast, and they are very knowledgeable."
"Pandora FMS is an all-in-one solution that is cost-efficient."
"Network monitoring is fun again with Pandora FMS."
"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."
"The most valuable feature is that it is an all-in-one monitoring system."
"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."
 

Cons

"There's no convenient way to manage notes as the only way is to manage them through the database."
"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."
"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 important separation between Interface and Core to maintain historical plugins and methods generate complexity that makes Nagios unusable for repeat work."
"Nagios XI can improve its GUI for users with a new look."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"We'd like to see more integration capabilities."
"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."
"Improvements are needed for server and network discovery, including service-based discovery."
"In its versions for Linux, in the beginning, it can be somewhat complicated to configure and implement."
"Pandora could deliver better analytics out of the box."
"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 find that this software is resource heavy, and demands a lot of processing capacity."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"An update to the Android app would be appreciated."
 

Pricing and Cost Advice

"The licensing fees for this solution are approximately $3,000 USD per year."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"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."
"The pricing is high with separate licensing for the product and support."
"We are using the free version of this solution."
"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."
"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."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"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."
