Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years.
Nagios Core excels in notification capabilities and real-time reporting, featuring graphical insights and configurability for plugins. Its stability and lightweight design are valued for efficient infrastructure monitoring. Open-source nature allows customization, though setup involves complexity. While scalability and bandwidth monitoring need enhancement, its free version limits functionality. Engaging a dedicated manager for support could enhance user experience. Despite these challenges, its strengths in alerts and data presentation are notable.
