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 application?

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 for performance monitoring?

Focus on metrics like CPU usage, memory consumption, event loop latency, and request/response times. These will give you a good overview of your application's performance.

Are there any specific logging practices I should follow?

Yes, use structured logging with tools like Winston or Bunyan. Ensure logs are easily searchable and include relevant context, such as timestamps and request IDs.
