Application Performance Monitoring (APM): New Relic

 

New Relic Overview

New Relic is an observability and monitoring platform that helps developers, DevOps, and IT teams track, troubleshoot, and optimize application performance in real time. It provides deep insights into system performance, infrastructure health, and user experiences.

Key Features of New Relic

1. Application Performance Monitoring (APM) – Tracks the performance of applications, including latency, errors, and transaction tracing.
2. Infrastructure Monitoring – Monitors servers, cloud environments, and containerized applications (e.g., Kubernetes).
3. Log Management – Collects, analyzes, and visualizes logs in real-time.
4. Synthetic Monitoring – Simulates user interactions to test application performance before real users experience issues.
5. Distributed Tracing – Helps track requests across microservices-based applications.
6. Alerting & Incident Management – Sends alerts based on predefined performance thresholds.
7. Security & Compliance Monitoring – Detects vulnerabilities and security risks in applications.
8. Custom Dashboards & Analytics – Uses New Relic Query Language (NRQL) to create real-time performance dashboards.

Use Cases

• Monitoring cloud-native applications and on-prem systems.
• Troubleshooting performance bottlenecks in applications.
• Ensuring high availability and reliability of web and mobile apps.
• Tracking real-time user experience and optimizing digital interactions.
• Enhancing DevSecOps and SRE workflows by integrating with CI/CD pipelines.

New Relic vs. Other Monitoring Tools

• Competes with Datadog, Dynatrace, Prometheus, Grafana, and Splunk in observability.
• Offers full-stack monitoring, whereas some tools focus on specific areas (e.g., Prometheus for metrics, Splunk for logs).

New Relic with Secured connection from:

SSL (Secure Sockets Layer) is a security protocol that establishes an encrypted link between a web server and a web browser. It ensures that all data transmitted between them remains private and secure.

Key Points About SSL:

• Encrypts data to protect it from hackers and eavesdroppers.
• Used in HTTPS (HyperText Transfer Protocol Secure) to secure websites.
• Prevents man-in-the-middle (MITM) attacks and data tampering.
• Replaced by TLS (Transport Layer Security), but people still commonly refer to "SSL" when they mean TLS.

How to Identify SSL on a Website:

• The URL  should starts with https://
• A padlock icon 🔒 appears in the browser address bar.

When using New Relic APM (Application Performance Monitoring), here are key questions to keep in mind:

1. Performance & Bottlenecks

• What are the top slowest transactions in my application?
• Which external dependencies (databases, APIs, third-party services) are causing performance issues?
• Are there any database queries that take too long to execute?
• How is my application performing during peak usage periods?

2. Error & Failure Analysis

• What are the most common errors in my application?
• Are there any unusual spikes in error rates?
• Do specific transactions correlate with increased error rates?
• What is the response time of failing transactions compared to successful ones?

3. Scalability & Infrastructure

• How is the application performing across different environments (staging, production, etc.)?
• Is the infrastructure (CPU, memory, disk usage) sufficient for current workloads?
• Are there any memory leaks or resource exhaustion issues?
• What is the impact of autoscaling on application performance?

4. User Experience & Latency

• What is the average response time for user requests?
• How does application performance vary across different geographic locations?
• Are there any frontend performance issues affecting user experience?

5. Alerting & Monitoring Strategy

• Are my alert thresholds properly configured for proactive monitoring?
• Do my alerts provide actionable insights, or are they generating noise?
• How quickly can I detect and respond to incidents using New Relic?

6. Deployment & Release Impact

• How do recent code deployments affect application performance?
• Are there any new bottlenecks introduced after a release?
• Can I correlate performance issues with specific deployments?

7. Distributed Tracing & Dependencies

• How do requests propagate across microservices?
• Are any microservices experiencing higher latency than usual?
• How can I optimize communication between services?
