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.

​It offers a simple implementation of business and infrastructure dashboards but the monitoring services need improvement.

"Nagios XI helped me to draw the network and check for system failures."
"The alerting system is very effective."
"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 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 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."
"Overall, it's a powerful system."
"Since we started using OpMon, we have increased our assertiveness and consequently reduced costs with fewer errors."
"As a consulting company we implement management solutions to a large variety of companies and after working with OpMon our project time was reduced and we can offer a different solution to each customer."
 

Cons

"The scalability of Nagios XI is scalable. However, it is not easy to do."
"We'd like to see more integration capabilities."
"We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios."
"The product does not have SAP monitoring."
"Backup mechanisms and some kind of templating system for dashboards are needed."
"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."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
"As it is open-source, it is not user-friendly. Open-source software is usually not user-friendly."

Pricing and Cost Advice

"The pricing is high with separate licensing for the product and support."
"The licensing fees for this solution are approximately $3,000 USD per year."

"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."
"As it is not an agentless tool, I think it is expensive."

"We are using the free version of this solution."
"Licensing costs are reasonable."
