Nagios XI offers customizable monitoring for processes, services, and performance, supporting plugins for extensive device management. Users benefit from timely alerts, yet challenges exist with PNP4Nagios plugin compatibility, limited network map customization, and variable 24/7 technical support. Integrating other systems for security alerts requires custom plugins due to unavailable features. Despite integration challenges, Nagios XI remains effective for various applications from small software to complex IT infrastructures.
