Logging

Use structured logging for consistent, searchable diagnostics across steps.

MDC Context

Attach pipeline identifiers to MDC so logs can be correlated across services:

MDC.put("pipelineId", pipelineId);
MDC.put("stepName", stepName);

JSON Logging

Prefer JSON logs in production to integrate with log aggregation.

quarkus.log.console.json=true
quarkus.log.console.json.pretty-print=false

Log Levels

1. DEBUG: Development diagnostics
2. INFO: Business events and step completion
3. WARN: Recoverable issues
4. ERROR: Failures and retries

Logging Standards

1. Avoid logging full payloads
2. Mask secrets and PII
3. Keep messages consistent across steps
