Logging

Overview

Effective logging is essential for debugging, monitoring, and understanding application behavior. This skill covers structured logging patterns using Serilog.

Definition of Done (DoD)

• All significant operations are logged with appropriate level
• Logs include correlation IDs for request tracing
• Sensitive data is never logged (passwords, tokens, PII)
• Log messages are structured (use templates, not string concatenation)
• Errors include exception details and context
• Log levels are appropriate (not everything is Warning/Error)
