Executive SummaryUpdated on Feb 8, 2026

Nagios XI and Centreon both compete in the network and IT infrastructure monitoring solutions market. Centreon appears to take the upper hand by providing clearer data visualization and comprehensive dashboards, which can significantly enhance user experience and impact analysis.

Features: Nagios XI is notable for its extensive plugin ecosystem, customizable script support, and ability to integrate diverse metrics. It provides a high degree of extensibility, allowing tailored monitoring setups. Centreon offers comprehensive dashboards and data visualization tools, as well as flexibility with third-party module integration, adding value to infrastructure health monitoring.

Room for Improvement: Nagios XI can be challenging due to the need for technical know-how for configuration and the absence of a built-in API for seamless integration. Its interface and documentation could also be improved for easier usability. Centreon could benefit from enhanced cloud monitoring characteristics and improvements in its network discovery capabilities. Users have suggested improvements in API functionality and integration capabilities.

Ease of Deployment and Customer Service: Nagios XI is primarily deployed on-premises, supported by a strong community, though official support can be costly. Some customers have had mixed experiences with technical support logistics. Centreon is appreciated for an on-premises and hybrid setup, boasting a user-friendly interface that facilitates deployment and professional support, though its pricing model has led to confusion.

Pricing and ROI: Nagios offers a free version with Nagios Core and a paid version with Nagios XI. The open-source nature of Nagios Core provides quick ROI despite configuration needs, whereas Nagios XI provides good value with its adaptability. Centreon's pricing is considered fair, beginning around 5000 euros and rising with usage, justified by its robust features and professional support. Both platforms show time-saving potential and ROI advantages depending on the scale of deployment.

While Centreon excels at server-level monitoring, it lacks the ability to track web app availability and latency, unlike Dynatrace, which is efficient in this area.

Experience enhanced monitoring with real-time alerts and efficient support

I would like to see automation in the poller features, as currently, the poller is not automated. If we could automate the addition or removal of hosts in the poller, it would improve efficiency. Sometimes, Centreon does not show the status of services as updated, which should be addressed. Additionally, enhancements are needed in identifying configuration issues, providing real-time alerts in case of issues, and improving the HTTP configuration tasks, as Centreon does not currently display issues with HTTP links, requiring manual investigation.

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.
