ACTIVITY-LOG

Activity log. See Enterprise Integration Patterns.

Definition

Activity log — chronological log of a system's activity, tracing all technical and functional actions with timestamp, author and outcome. Distinct from the audit trail (which targets non-repudiation).

Origin

Pattern described in observable architectures (Sigelman et al., Dapper paper, Google, 2010). The activity log feeds SIEM, APM tools, and L1 support.

Use

On an EDI gateway, the activity log traces: file arrival on SFTP, parse OK/KO, applied mapping, AS2 send, MDN reception. Indexed by trace-id for correlation.
