Nagios XI and Nagios Core compete in the network monitoring market offering solutions for server and network performance monitoring. Based on the data, Nagios XI seems to have the upper hand due to its user-friendly interface and integrated configuration tools, which are not available in Nagios Core.
Features: Nagios XI provides an enterprise-level monitoring solution with robust performance monitoring, in-depth dashboards, and extensive customization options. It allows users to write custom plugins and offers a rich array of out-of-the-box features. Nagios Core, as an open-source platform, is appreciated for its simplicity and efficacy in monitoring essential network services, excels in customization and extensibility, and provides the capability to write your own plugins.
Room for Improvement: Nagios XI is criticized for its configuration complexity, with users desiring enhanced integration capabilities and improvements in reporting and dashboard intuitiveness. Nagios Core lacks a user-friendly interface and built-in configuration utilities, requiring manual configurations, yet offers powerful performance and flexibility for tech-savvy users.
Ease of Deployment and Customer Service: Nagios XI offers straightforward deployment with integrated tools for private and hybrid cloud environments, while Nagios Core demands significant configuration effort. Both benefit from a large user community, but Nagios XI users typically receive better technical support due to its commercial nature, whereas Nagios Core users rely on community resources.
Pricing and ROI: Nagios XI is a paid solution with a licensing fee considered reasonable by users compared to competitors, providing substantial returns through time savings and improved monitoring. Nagios Core, being free and open-source, offers excellent value for those capable of handling its configurations, but its setup complexity may reduce initial ROI.
The solution is scalable.
If the user interface isn’t presenting data well, it becomes difficult to manage when scaling.
I tried many other solutions at work, however, in terms of Nagios, I haven't seen any disruption or downtime.
It is very stable.
Many tools have poor user interfaces, making them hard to manage and navigate.
The GUI could be improved. It's a bit too basic.
We are using the free, open-source version.
The pricing for the Nagios XI product is good and better than other solutions.
It has a very handy dashboard, providing live alerts and visibility for everything.
Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.
The alerting system is very effective.

Reviews from Real Users
Nagios XI stands out among its competitors for a number of reasons. Several major ones are its integration options and monitoring abilities, as well as its alerting features.
David P., a senior DevOps engineer at EML Payments Ltd, writes, “We use Nagios as a network discovery tool. We use Nagios to maintain our uptime statistics and to monitor our services. It has allowed us to be much more sophisticated in our monitoring and alerting.”
An IT-OSS manager at a comms service provider notes, “Nagios XI has a custom API feature, and we can expose custom APIs for our integration. This is a great feature.”
