n8nTrace — Grafana-like observability for n8n workflows. Self‑hosted TypeScript app: execution tracking, Prometheus explorer, RBAC, audit logs, Postgres. MIT license. Worth a look if you run n8n in production. Repo: https://github.com/Mohammedaljer/n8nTrace
What it actually adds: per-workflow execution traces (not just logs), an in-app Prometheus metrics explorer, role-based access control, and audit logging. Security-first + self-hosted reduces leak risk—at the cost of ops and storage you must manage.
Practical playbook: export metrics like n8n_workflow_execution_total and n8n_node_duration_seconds_bucket. Raw executions: 7–30 days retention; aggregated metrics: 90+ days. Set alerts: error_rate >2% over 5m or 95th‑pct node latency >2x baseline.
If you support regulated clients (legal, finance, agencies): fork, Docker‑compose it, connect Prometheus, seed RBAC from CI, and enforce mandatory human review before publish. Which piece would you rather run yourself vs accept as SaaS for compliance?
