+# ThrillWiki Monitoring Setup
+
+## Overview
+
+This document describes the automatic metric collection system for anomaly detection and system monitoring.
+
+## Architecture
+
+The system collects metrics from two sources:
+
+1. **Django Backend (Celery Tasks)**: Collects Django-specific metrics like error rates, response times, queue sizes
+2. **Supabase Edge Function**: Collects Supabase-specific metrics like API errors, rate limits, submission queues
+
+## Components
+
+### Django Components
+
+#### 1. Metrics Collector (`apps/monitoring/metrics_collector.py`)
+- Collects system metrics from various sources
+- Records metrics to Supabase `metric_time_series` table
+- Provides utilities for tracking:
+  - Error rates
+  - API response times
+  - Celery queue sizes
+  - Database connection counts
+  - Cache hit rates
+
+#### 2. Celery Tasks (`apps/monitoring/tasks.py`)
+Periodic background tasks:
+- `collect_system_metrics`: Collects all metrics every minute
+- `collect_error_metrics`: Tracks error rates
+- `collect_performance_metrics`: Tracks response times and cache performance
+- `collect_queue_metrics`: Monitors Celery queue health
+
+#### 3. Metrics Middleware (`apps/monitoring/middleware.py`)
+- Tracks API response times for every request
+- Records errors and exceptions
+- Updates cache with performance data
+
+### Supabase Components
+
+#### Edge Function (`supabase/functions/collect-metrics`)
+Collects Supabase-specific metrics:
+- API error counts
+- Rate limit violations
+- Pending submissions
+- Active incidents
+- Unresolved alerts
+- Submission approval rates
+- Average moderation times
+
+## Setup Instructions
+
+### 1. Django Setup
+
+Add the monitoring app to your Django `INSTALLED_APPS`:
+
+```python
+INSTALLED_APPS = [
+    # ... other apps
+    'apps.monitoring',
+]
+```
+
+Add the metrics middleware to `MIDDLEWARE`:
+
+```python
+MIDDLEWARE = [
+    # ... other middleware
+    'apps.monitoring.middleware.MetricsMiddleware',
+]
+```
+
+Import and use the Celery Beat schedule in your Django settings:
+
+```python
+from config.celery_beat_schedule import CELERY_BEAT_SCHEDULE
+
+CELERY_BEAT_SCHEDULE = CELERY_BEAT_SCHEDULE
+```
+
+Configure environment variables:
+
+```bash
+SUPABASE_URL=https://api.thrillwiki.com
+SUPABASE_SERVICE_ROLE_KEY=your_service_role_key
+```
+
+### 2. Start Celery Workers
+
+Start Celery worker for processing tasks:
+
+```bash
+celery -A config worker -l info -Q monitoring,maintenance,analytics
+```
+
+Start Celery Beat for periodic task scheduling:
+
+```bash
+celery -A config beat -l info
+```
+
+### 3. Supabase Edge Function Setup
+
+The `collect-metrics` edge function should be called periodically. Set up a cron job in Supabase:
+
+```sql
+SELECT cron.schedule(
+  'collect-metrics-every-minute',
+  '* * * * *', -- Every minute
+  $$
+  SELECT net.http_post(
+    url:='https://api.thrillwiki.com/functions/v1/collect-metrics',
+    headers:='{"Content-Type": "application/json", "Authorization": "Bearer YOUR_ANON_KEY"}'::jsonb,
+    body:=concat('{"time": "', now(), '"}')::jsonb
+  ) as request_id;
+  $$
+);
+```
+
+### 4. Anomaly Detection Setup
+
+The `detect-anomalies` edge function should also run periodically:
+
+```sql
+SELECT cron.schedule(
+  'detect-anomalies-every-5-minutes',
+  '*/5 * * * *', -- Every 5 minutes
+  $$
+  SELECT net.http_post(
+    url:='https://api.thrillwiki.com/functions/v1/detect-anomalies',
+    headers:='{"Content-Type": "application/json", "Authorization": "Bearer YOUR_ANON_KEY"}'::jsonb,
+    body:=concat('{"time": "', now(), '"}')::jsonb
+  ) as request_id;
+  $$
+);
+```
+
+## Metrics Collected
+
+### Django Metrics
+- `error_rate`: Percentage of error logs (performance)
+- `api_response_time`: Average API response time in ms (performance)
+- `celery_queue_size`: Number of queued Celery tasks (system)
+- `database_connections`: Active database connections (system)
+- `cache_hit_rate`: Cache hit percentage (performance)
+
+### Supabase Metrics
+- `api_error_count`: Recent API errors (performance)
+- `rate_limit_violations`: Rate limit blocks (security)
+- `pending_submissions`: Submissions awaiting moderation (workflow)
+- `active_incidents`: Open/investigating incidents (monitoring)
+- `unresolved_alerts`: Unresolved system alerts (monitoring)
+- `submission_approval_rate`: Percentage of approved submissions (workflow)
+- `avg_moderation_time`: Average time to moderate in minutes (workflow)
+
+## Monitoring
+
+View collected metrics in the Admin Monitoring Dashboard:
+- Navigate to `/admin/monitoring`
+- View anomaly detections, alerts, and incidents
+- Manually trigger metric collection or anomaly detection
+- View real-time system health
+
+## Troubleshooting
+
+### No metrics being collected
+
+1. Check Celery workers are running:
+   ```bash
+   celery -A config inspect active
+   ```
+
+2. Check Celery Beat is running:
+   ```bash
+   celery -A config inspect scheduled
+   ```
+
+3. Verify environment variables are set
+
+4. Check logs for errors:
+   ```bash
+   tail -f logs/celery.log
+   ```
+
+### Edge function not collecting metrics
+
+1. Verify cron job is scheduled in Supabase
+2. Check edge function logs in Supabase dashboard
+3. Verify service role key is correct
+4. Test edge function manually
+
+## Production Considerations
+
+1. **Resource Usage**: Collecting metrics every minute generates significant database writes. Consider adjusting frequency for production.
+
+2. **Data Retention**: Set up periodic cleanup of old metrics (older than 30 days) to manage database size.
+
+3. **Alert Fatigue**: Fine-tune anomaly detection sensitivity to reduce false positives.
+
+4. **Scaling**: As traffic grows, consider moving to a time-series database like TimescaleDB or InfluxDB.
+
+5. **Monitoring the Monitors**: Set up external health checks to ensure metric collection is working.
