When working with New Relic and Application Performance Monitoring (APM). 

keep these key questions in mind:

1. Application Performance & Bottlenecks

• What are the key performance metrics (response time, throughput, error rate) for my application?
• Which transactions or endpoints are the slowest?
• What external dependencies (databases, APIs, caches) are causing latency?
• Are there any trends in performance degradation over time?

2. Infrastructure & Resource Utilization

• How are CPU, memory, and disk I/O performing on my hosts and containers?
• Are there any resource bottlenecks affecting application performance?
• Are Kubernetes pods or cloud instances running at optimal capacity?

3. Errors & Failures

• What are the most frequent and critical errors in my application?
• Which transactions or services are generating the most errors?
• Can I trace these errors back to specific deployments or code changes?
• Are there patterns in error occurrences (e.g., specific regions, times of day)?

4. Distributed Tracing & Dependencies

• How are requests flowing through my microservices or distributed systems?
• Where are the slowest points in the request lifecycle?
• Are database queries or third-party services slowing down my application?
• Are there any unusual spikes in dependency failures?

5. Alerting & Incident Response

• Are alerts configured properly to detect anomalies before they impact users?
• Are alert thresholds optimized to minimize noise but still catch real issues?
• What is my Mean Time to Detect (MTTD) and Mean Time to Resolve (MTTR)?
• How can I integrate New Relic with Slack, PagerDuty, or other incident response tools?

6. Deployment & Change Analysis

• Did a recent deployment introduce a performance regression?
• What impact did a new release have on error rates and response times?
• Are there performance trends linked to specific code changes?

7. User Experience & Business Impact

• How is application latency affecting user experience?
• What percentage of transactions meet SLAs and SLOs?
• How does performance correlate with business metrics like conversion rates?

8. Security & Compliance

• Are there any anomalies or unexpected spikes in traffic?
• Is sensitive data properly monitored for security breaches?
• How can I use New Relic logs and traces for security audits?

APM - New Relic

APM (Application Performance Monitoring) in New Relic is a powerful tool for monitoring application performance, identifying bottlenecks, and improving system reliability. It provides deep insights into how applications perform in real-time, helping developers and DevOps teams optimize performance and troubleshoot issues efficiently.

Key Features of New Relic APM:

1. Real-time Monitoring – Tracks application performance metrics like response times, throughput, and error rates.
2. Distributed Tracing – Helps visualize request flows across microservices and pinpoint latency issues.
3. Error Tracking & Logging – Captures detailed error analytics and logs to aid debugging.
4. Custom Instrumentation – Allows developers to add custom metrics to monitor specific application behavior.
5. Database Performance Monitoring – Identifies slow queries and inefficient database interactions.
6. Alerting & Anomaly Detection – Provides alerts on performance degradation using AI-driven anomaly detection.
7. Service Maps – Offers a graphical view of how different services interact within an application.
8. Infrastructure Integration – Works with cloud platforms like AWS, Azure, and Kubernetes.

How to Use New Relic APM:

1. Install the New Relic Agent in your application (available for Java, Node.js, Python, Ruby, .NET, Go, and PHP).
2. Configure the Agent with your New Relic license key.
3. Deploy and Run the application to start collecting performance data.
4. Access the New Relic Dashboard to analyze metrics, set alerts, and optimize performance.

How to Install and Configure New Relic APM Agent

New Relic APM supports multiple programming languages like Java, Node.js, Python, .NET, PHP, Go, and Ruby. Below are the general steps to install, configure, and start monitoring an application using New Relic.

Step 1: Sign Up and Get Your New Relic License Key

1. Go to New Relic's website and create an account. https://newrelic.com/
2. Navigate to APM & Services → Click on Add a New Service.
3. Copy your New Relic License Key from the dashboard.

Step 2: Install the New Relic APM Agent

For Java Applications

1. Download the latest New Relic Java agent:

   curl -O https://download.newrelic.com/newrelic/java-agent/newrelic-agent/current/newrelic-java.zip
   

2. Unzip and move it to your application directory:

   unzip newrelic-java.zip -d /path/to/your/app
   

3. Add the agent to your JVM options:

   -javaagent:/path/to/your/app/newrelic/newrelic.jar
   

4. Modify the newrelic.yml configuration file to include your license key and application name.

For Node.js Applications

1. Install the New Relic agent using npm:

   npm install newrelic --save
   

2. Create a newrelic.js file in your project root:

   # js
   
   exports.config = {
     app_name: ["YourAppName"],
     license_key: "YOUR_NEW_RELIC_LICENSE_KEY",
     logging: {
       level: "info"
     }
   };
   

3. Require New Relic at the top of your main app file (e.g., server.js or app.js):

   # js
   
   require('newrelic');

For Python Applications

1. Install the New Relic Python agent:

   pip install newrelic
