In modern software development, application performance and infrastructure health are crucial for delivering a seamless user experience. New Relic is one of the leading observability and monitoring tools that provides real-time insights into system performance, helping developers, DevOps, and SREs optimize their applications effectively.
In this blog, we will explore the key metrics provided by New Relic and how they help in monitoring application health, debugging issues, and ensuring high availability.
1. Application Performance Monitoring (APM) Metrics
New Relic’s APM module helps developers track their application’s real-time performance. Some essential metrics include:
🔹 Response Time
- Measures the time taken by the application to process requests.
- Helps in detecting slow API endpoints.
🔹 Throughput (Requests Per Minute - RPM)
- Tracks the number of requests processed per minute.
- Helps scale applications based on load.
🔹 Error Rate
- Measures the percentage of requests that fail due to exceptions.
- Useful for debugging and improving stability.
🔹 Apdex Score (Application Performance Index)
- A user satisfaction score based on response times.
- Helps measure user experience.
🔹 Transaction Tracing
- Provides insights into how much time is spent in different parts of the code.
- Helps identify performance bottlenecks in functions, database queries, or external API calls.
🔹 Slowest Transactions
- Identifies time-consuming operations that impact the system.
2. Infrastructure & Server Monitoring Metrics
New Relic’s infrastructure monitoring provides deep insights into your servers and cloud environments.
🔹 CPU Usage
- Monitors CPU consumption per instance.
- Helps in identifying resource-intensive processes.
🔹 Memory Usage
- Tracks RAM usage in real time.
- Helps prevent memory leaks and out-of-memory errors.
🔹 Disk I/O
- Measures disk read/write operations.
- Helps optimize disk performance.
🔹 Network Traffic
- Monitors inbound and outbound data flow.
- Helps detect network bottlenecks.
🔹 Container Metrics
- Provides insights into Docker and Kubernetes container performance.
- Monitors pod health, CPU, and memory usage in Kubernetes environments.
3. Database Performance Metrics
Databases are often a major source of performance bottlenecks. New Relic helps in optimizing query performance with the following metrics:
🔹 Query Execution Time
- Measures the time taken to execute SQL queries.
- Helps optimize slow queries.
🔹 Slow Queries
- Identifies queries that take longer than expected.
- Helps in performance tuning.
🔹 Database Throughput
- Tracks database transactions per second.
🔹 Connection Pooling
- Monitors database connections to avoid exhaustion.
🔹 Cache Performance
- Measures hit/miss ratios in Redis, Memcached, and other caching solutions.
4. Logs & Distributed Tracing
New Relic’s logging and tracing features help in tracking request flows across distributed systems.
🔹 Live Logging
- Aggregates logs from multiple sources in real time.
- Integrates with Logstash, Fluentd, and ELK Stack.
🔹 Trace Context Propagation
- Tracks requests as they move between microservices.
🔹 Span Events
- Provides deep insights into function execution time and external API calls.
5. Frontend & User Experience Monitoring
New Relic also provides metrics for browser monitoring to track user experience.
🔹 Page Load Time
- Measures the total time taken to load a page.
🔹 Time to First Byte (TTFB)
- Indicates how fast the server responds to a request.
🔹 DOM Interactive Time
- Measures how long it takes to parse and load the HTML.
🔹 JavaScript Errors
- Captures client-side errors.
🔹 User Sessions & Engagement
- Tracks active users and their interactions.
6. Synthetic & Real User Monitoring (RUM)
- Synthetic Checks: Runs automated tests on applications from different locations.
- Real User Monitoring (RUM): Collects actual performance data from real users.
- Third-Party API Monitoring: Tracks the response times of third-party APIs.
7. DevOps & CI/CD Monitoring
New Relic also integrates with DevOps pipelines and CI/CD processes.
🔹 Deployment Tracking
- Correlates performance changes with deployments.
🔹 Pipeline Monitoring
- Observes build and release times.
🔹 Error Regression
- Detects new errors introduced in recent releases.
8. Security & Compliance Metrics
Security is a critical aspect of observability. New Relic provides:
🔹 Security Vulnerabilities
- Identifies security flaws in dependencies.
🔹 Anomaly Detection
- Uses AI/ML to detect unusual activity.
🔹 Compliance Audits
- Ensures adherence to industry standards like GDPR, HIPAA, and PCI DSS.
9. Cloud & Kubernetes Monitoring
New Relic provides deep integration with cloud platforms.
🔹 Kubernetes Pod Health
- Monitors pod restarts, failures, and resource usage.
🔹 Cloud Service Monitoring
- Integrates with AWS, Azure, and GCP.
🔹 Lambda Execution Time
- Tracks AWS Lambda function execution performance.
Conclusion
New Relic offers a comprehensive observability solution for applications, databases, infrastructure, and user experience. Whether you're troubleshooting slow APIs, monitoring Kubernetes clusters, or tracking CI/CD deployments, New Relic provides actionable insights to optimize performance.
