What analytical information do you collect during the development of a software product?

During the development of a software product on Node.js, I gather the following analytical information:

• Application logs (errors, warnings, important events) for diagnostics and monitoring.
• Performance metrics (response time, memory and CPU usage) for optimization.
• Usage statistics of APIs or functions (e.g., which endpoints are called most often) to understand user behavior.
• Error and exception information with stack trace details for quick bug fixing.

Tools often used for collecting such information include logging tools (winston, pino), monitoring tools (Prometheus, New Relic), and tracing tools (Jaeger, OpenTelemetry).
