FAQ

What is Log to Sequence Diagram for?

Turn simple service call logs into a Mermaid sequence diagram.

Does it require an account?

No. The tool page can be used directly in the browser.

Log to Sequence Diagram is designed for developer documentation, AI-generated diagram validation, and engineering configuration visualization.

It helps convert source text, config, or AI output into a previewable and exportable result.

Demo: turn service logs into a sequence diagram

Logs often describe a flow but hide it across many lines. A sequence diagram helps reconstruct service calls during debugging, especially when request IDs are available.

  • Group log lines by trace ID or request ID before conversion.
  • Extract caller, callee, action, and status from each line.
  • Keep timestamps available for latency interpretation.
10:00:01 gateway -> api POST /orders trace=abc
10:00:02 api -> payment authorize trace=abc
10:00:03 payment -> api approved trace=abc

Debugging: avoid inventing calls from vague logs

Log-to-diagram conversion should stay conservative. If a line does not identify both sides of an interaction, represent it as a note or omit it from the call chain.

  • Do not infer a downstream call from a generic error message.
  • Use notes for warnings, retries, and local validation.
  • Keep raw log snippets near the diagram for auditability.

Checklist de revue pour Log to Sequence Diagram

Utilisez Log to Sequence Diagram pour inspecter visuellement une source avant documentation, note de PR, post-mortem ou transfert. Turn simple service call logs into a Mermaid sequence diagram.

Avant export, vérifiez la lisibilité, les relations, les données sensibles et la cohérence après modification.

Limites et dépannage

Si l'aperçu échoue, réduisez l'entrée au plus petit exemple complet, validez la syntaxe puis réajoutez les sections.

Considérez l'aperçu comme une surface de revue, pas comme une source de vérité. Les résultats critiques doivent être validés.

Exemples à tester

  • API: client -> web: GET /orders web -> api: fetch orders api -> database: SELECT orders database -> api: rows api -> web: JSON
  • Payment: checkout -> payment: create intent payment -> bank: authorize bank -> payment: approved payment -> checkout: paid
  • Incident: api -> auth: validate token auth -> api: timeout api -> retry: retry request retry -> auth: validate token
