INSIGHT

Per-Execution Telemetry Unlocks Visibility

  • Enterprises need per-execution telemetry to know not just failures but why they fail and how much workflows cost.
  • Capturing full execution JSON enables monitoring, cost-tracking, and automated analysis.
ADVICE

Use Post-Execution Hooks To Capture Telemetry

  • Use n8n backend hooks, specifically post-execution, to capture full workflow JSON after each run.
  • Push that JSON to a database like Supabase to enable later analysis and alerting.
ADVICE

Store And Serve Telemetry Securely

  • Store parsed execution fields plus the full JSON in Supabase using a clear schema and indices.
  • Protect access by serving data from the Next.js backend routes, not exposing Supabase anon keys to the frontend.
