What are the best practices for monitoring Node.js applications?

To effectively monitor Node.js applications, consider using tools like PM2, New Relic, or Datadog. It's important to track metrics such as response times, error rates, and memory usage.

How can I set up alerts for my Node.js app?

You can set up alerts using monitoring tools like New Relic or Datadog. Configure thresholds for key metrics, and the tool will notify you via email or SMS when those thresholds are breached.

What metrics should I focus on?

Focus on metrics like CPU usage, memory consumption, request latency, error rates, and throughput. These will give you a comprehensive view of your app's performance.

Are there any specific logging practices I should follow?

Yes, use structured logging to capture key information in a consistent format. Tools like Winston or Bunyan can help with this. Ensure logs include timestamps, log levels, and relevant context.

Can I monitor my app's performance in real-time?

Absolutely! Tools like Grafana and Prometheus allow you to visualize metrics in real-time, helping you to quickly identify and address performance issues.
