Executive SummaryUpdated on Apr 20, 2025

New Relic and Nagios Core both compete in the monitoring software category. Based on our comparison, New Relic has the upper hand in terms of ease of installation and application performance monitoring, while Nagios Core stands out for its cost-effectiveness and customization capabilities.

Features: New Relic's features include real-time performance statistics for comprehensive APM, database query analysis to improve performance, and intuitive integration with high-level dashboards, making it user-friendly for both developers and operations teams. Nagios Core provides flexibility with its open-source model, allowing for extensive customizations, a wide variety of plugins for infrastructure monitoring, and robust reliability and adaptability in different IT environments.

Room for Improvement: New Relic needs to address concerns such as data privacy issues, high costs, and limited alerting customization. Users have called for better configuration management and improved historical data retention. Nagios Core could enhance its user interface and streamline configuration processes to overcome setup and dashboard aesthetic challenges, as it currently demands significant technical expertise to manage effectively.

Ease of Deployment and Customer Service: New Relic's deployment is seamless in public and hybrid cloud environments, providing strong scalability and benefiting enterprises with cloud-native needs. It enjoys robust customer service but occasionally lacks immediate support for complex situations. Nagios Core is better suited for on-premises deployment, aligning with the flexibility of its open-source nature. While it provides satisfactory support, it heavily relies on community-driven solutions.

Pricing and ROI: New Relic has a licensing requirement, viewed as expensive by some, though the comprehensive monitoring benefits are seen as justifying the cost for those utilizing its capabilities, with ROI realized through enhanced efficiency and reduced downtime. Nagios Core, being free and open-source, offers a cost-effective advantage for users who can handle its manual configurations. While financial ROI isn't often quantified, its no-cost licensing and inherent flexibility make it appealing for budget-conscious organizations.

Valuable reporting and alert system with room for PDF export improvements

The NetEase reporting structure needs improvement, especially the availability report, which is weak. It should be generated automatically with minimal human intervention and should be exportable as a PDF. Besides that, an integrated PDF export feature for reports is necessary. Also, the alert mechanism and graphing mechanism need to be integrated properly into Nagios Core. Currently, integrating these requires advanced Linux knowledge. Integration of more visualization tools like Grafana and Prometheus for better graphing and visualization is also recommended.

Chief Technology Officer at State of Hawaii

Has a simple user interface and end-to-end monitoring and self-healing features

My organization uses many application performance management solutions, such as AppDynamics, New Relic APM, Splunk, and Datadog. I'm the CTO for the state of Hawaii, and across the board, different departments use different APM tools. I'm using the latest version of New Relic APM, but I cannot recall the exact version. My company has a dozen engineers using and monitoring New Relic APM. I'd tell anyone planning to use New Relic APM that it has to fit what you have. For example, most of my company's payload is in AWS, and the tool has adopters and features that CloudWatch cannot provide. Still, New Relic APM can, so you should do a demo or trial run first and see if it's a tool that'll help you with end-to-end monitoring. New Relic APM is working well for my company, so an excellent way to start is to do a trial run to see how the tool works out for your current applications. My rating for the tool is nine out of ten because my experience with it has been great. New Relic also worked closely with my company and has always been upfront on what's available and what's not. My company is a New Relic APM customer.
