The good thing about Nagios Core is it covers everything.
Nagios Core delivers proactive alerts and enhances SLA performance with its highly configurable monitoring capabilities, ensuring rapid resolution through timely notifications. Integrating smoothly with tools such as Splunk and Datadog, its open-source flexibility supports custom plugins. Despite its strengths, Nagios Core faces complexity in setup, limited cloud monitoring plugins, and scalability issues, with inefficiencies in bandwidth monitoring compared to alternatives like Cacti, alongside integration improvements needed for better functionality.
