RAG Pipeline Monitor

Who is this for?

RAG monitoring n8n workflow for AI engineers watching Supabase telemetry with drift, p95 and error spikes on a 15-min schedule. Telemetry, logs and daily status scatter across HTTP endpoints, Supabase, Sheets and Slack when checked by hand. You import the dg-1008 JSON slug-specific with exact credentials, tested first-try, and Supabase plus Sheets plus Slack wiring is ready to verify.

What problem does this solve?

You open the HTTP telemetry endpoint to pull drift and latency, query Supabase rag_metrics for 24h trends, then draft the health note and post to Slack #rag-ops by hand. On schedule, this workflow fetches telemetry via HTTP, flags drift with Code, logs to Supabase and Sheets with Wait cooldown, and sends the 8am Gmail report from a Supabase 24h pull. You just check the Gmail summary and Slack alerts.

What this workflow does

1. Schedule fires every 15 min → HTTP fetches RAG telemetry (drift, p95 latency, error rate)
2. Code flags drift > 0.08 cosine, p95 > 1200ms, or errors > 1%
3. Anomalies log to Supabase + archive to Sheets, alert Slack #rag-ops (15-min cooldown via Wait)
4. A second Schedule runs daily 8am → Supabase pulls 24h metrics → Gmail sends the team report

How it works

A Schedule fires every 15 min → HTTP fetches RAG telemetry → Code flags drift, p95 and error rate → Supabase plus Sheets log with Wait cooldown and Slack #rag-ops alert; a second Schedule runs daily 8am → Supabase pulls 24h metrics → Gmail sends the team report.

Setup

1. Open danielgrey.shop/app/templates/dg-1008 → Copy JSON → n8n → Import from Clipboard (or Push to n8n)
2. Connect credentials: Supabase, Slack, Google Sheets, Gmail, HTTP Header Auth
3. Check the Schedule timing, run once manually to verify — Time required: ~10 min review — then Activate.

Requirements

- n8n 1.50.0 or later
- Credentials for Supabase, Slack, Google Sheets, Gmail, HTTP Header Auth
- One-time $1200 — yours forever, Pro unlocks it too.

Customising

- Tune thresholds in Code for drift, p95 and error rate to match your SLOs.
- Change timing in Schedule triggers and tab mapping in Supabase and Sheets for Metrics.
