1. Pricing Model: New Relic offers a flexible pricing model based on the number of hosts or containers being monitored, allowing users to scale their usage as needed. On the other hand, PagerDuty follows a user-based pricing model, where the cost is determined by the number of users accessing the system. This difference in pricing models allows organizations to choose the most suitable option based on their specific needs and budget.

2. Focus of Monitoring: New Relic primarily focuses on application performance monitoring (APM) and provides comprehensive visibility into the performance of web and mobile applications. It offers features like real-time monitoring, code-level diagnostics, and precise application metrics. In contrast, PagerDuty is a incident management platform that focuses on real-time alerting and incident response. It centralizes alerts from various sources and enables efficient incident resolution through automated processes.

3. Alerting Capabilities: New Relic provides flexible alerting capabilities, allowing users to set up custom alerts based on specific metrics and thresholds. It supports multiple notification channels, such as email and SMS, to ensure that the right people are notified promptly. PagerDuty, on the other hand, offers advanced alerting and on-call scheduling features. It includes options like phone calls and push notifications for critical alerts, and also provides escalation policies to ensure that alerts are routed to the right person or team based on predefined rules.

4. Integration Ecosystem: New Relic offers a wide range of integrations with popular third-party tools and services, such as AWS, Azure, and Slack. This enables users to correlate performance data from different sources and get a holistic view of their environment. PagerDuty also provides integrations with various monitoring, collaboration, and ticketing tools to facilitate seamless incident management. Its integration capabilities allow teams to enhance their existing workflows and streamline their incident response processes.

5. Visualization and Reporting: New Relic provides interactive and customizable dashboards that enable users to visualize and analyze performance data in real-time. It also offers reporting features that allow users to generate detailed reports on application performance, response times, error rates, and more. On the other hand, PagerDuty focuses more on providing actionable insights rather than visualizations. It offers incident analytics and trend analysis to help teams identify patterns and make data-driven decisions to improve incident management.

6. Community and Support: New Relic has a vibrant community of users and provides extensive documentation, forums, and knowledge bases to support users in troubleshooting and optimizing their applications. It also offers different levels of support plans, including 24/7 technical support, to ensure that users get timely assistance when needed. PagerDuty also has an active community and provides resources like webinars, events, and customer forums. It offers various support plans, including a dedicated customer success manager, to cater to the specific needs of organizations.

In summary, New Relic and PagerDuty have key differences in their pricing models, focus of monitoring, alerting capabilities, integration ecosystems, visualization and reporting features, and community and support offerings. Organizations can choose between these tools based on their specific requirements for application performance monitoring and incident management.
