2. Choose the appropriate subscription plan based on your organization's needs and requirements.

Step 2: Instrumentation

1. Install the New Relic APM agent in your application environment.
2. Configure the agent to monitor your application code, frameworks, and dependencies.
3. Ensure that the agent is compatible with your programming language and runtime environment.

Step 3: Dashboard Creation

1. Access the New Relic APM dashboard through the New Relic web interface.
2. Customize dashboards to monitor key performance metrics such as response times, throughput, error rates, and resource utilization.
3. Set up alerts and notifications to proactively monitor and respond to performance issues.

Key Features of New Relic APM

1. Transaction Tracing: Trace individual transactions across distributed systems to identify performance bottlenecks and latency issues.
2. Code-Level Insights: Drill down into application code to identify slow database queries, external service calls, and inefficient code paths.
3. Error Analysis: Monitor and analyze error rates, error types, and error details to troubleshoot and resolve issues quickly.
4. Dependency Mapping: Visualize dependencies between application components, services, and infrastructure to understand system architecture and performance dependencies.
5. Real-Time Monitoring: Monitor application performance in real-time and receive instant alerts and notifications for critical events and anomalies.

Best Practices for New Relic APM Setup

1. Instrumentation Strategy: Instrument all critical components of your application stack, including web servers, application servers, databases, and third-party services.
2. Granular Monitoring: Monitor performance metrics at a granular level, including transaction traces, database queries, external API calls, and resource utilization.
3. Custom Metrics: Define custom metrics and transactions to monitor application-specific performance indicators and business metrics.
4. Integration with CI/CD Pipelines: Integrate New Relic APM into your CI/CD pipelines to monitor performance during development, testing, and deployment stages.
5. Continuous Optimization: Continuously monitor and optimize application performance based on insights from New Relic APM, including code refactoring, query optimization, and infrastructure scaling.
6. Security and Compliance: Ensure that sensitive data is handled securely and in compliance with data protection regulations when using New Relic APM.

Advanced Techniques for New Relic APM

1. Custom Instrumentation: Use custom instrumentation to monitor specific methods, functions, or transactions within your application code.
2. Distributed Tracing: Implement distributed tracing to trace requests across microservices and distributed systems for end-to-end performance monitoring.
3. Custom Dashboards and Alerts: Create custom dashboards and alerts tailored to your organization's specific requirements and use cases.
4. Integration with Other Tools: Integrate New Relic APM with other monitoring and observability tools such as logging platforms, infrastructure monitoring solutions, and incident management systems.
5. Performance Testing and Benchmarking: Use New Relic APM to conduct performance testing and benchmarking to evaluate application performance under different load conditions.
