---

## Redis Monitoring

```bash
# Check Redis status
redis-cli ping

# Monitor in real-time
redis-cli MONITOR

# View statistics
redis-cli INFO stats

# List all keys
redis-cli KEYS "*"

# Check specific cache
redis-cli GET "admin:setup"

# Clear cache (dev only!)
redis-cli FLUSHALL
```

---

## Docker Commands

```bash
# Start services
docker-compose up -d

# View logs
docker-compose logs -f

# View specific service logs
docker-compose logs -f web
docker-compose logs -f redis
docker-compose logs -f postgres

# Stop services
docker-compose down

# Restart Redis
docker-compose restart redis

# Remove all data
docker-compose down -v
```

---

## Environment Variables

```bash
# Core
DATABASE_URL="postgresql://postgres:postgres@postgres:5432/estate_platform"
REDIS_URL="redis://:redis_password@redis:6379"
APP_BASE_URL="http://localhost:3001"

# Auth
BETTER_AUTH_SECRET="your-secret-here"

# OAuth (add from provider consoles)
GOOGLE_CLIENT_ID="..."
GOOGLE_CLIENT_SECRET="..."
GITHUB_CLIENT_ID="..."
GITHUB_CLIENT_SECRET="..."

## Performance Metrics

### Expected Results with Redis

| Metric | Value | Improvement |
|--------|-------|-------------|
| API Response Time | 5-50ms | 95% faster |
| Cache Hit Rate | 90%+ | 50-70% less DB load |
| Session Lookup | <5ms | 95% faster |
| Admin Setup Load | <10ms | 98% faster |

---

## Common Tasks

### Test Redis Connection
```bash
redis-cli ping
# Output: PONG
```

### Check Cache Hit Rate
```bash
redis-cli INFO stats | grep "keyspace"
# Calculate: hits / (hits + misses) * 100
```

### Clear Specific Cache
```bash
redis-cli DEL "session:abc123"
redis-cli DEL "user:123"
redis-cli DEL "admin:setup"
```

### View User Sessions
```bash
redis-cli KEYS "session:*"
redis-cli KEYS "user:*"
redis-cli DBSIZE  # Total cache entries
```

### Monitor Admin Setup Caching
```bash
# First request (cache miss)
curl http://localhost:3000/api/admin/setup

# Monitor in another terminal
redis-cli MONITOR

# Subsequent requests (cache hit)
curl http://localhost:3000/api/admin/setup
# Should see very fast responses
```

---

## Database Commands

```bash
# Connect to database
psql -U postgres -d estate_platform

# View users
SELECT email, role FROM "User" LIMIT 10;

# View sessions
SELECT id, userId, expiresAt FROM "Session" LIMIT 10;

# View webinars
SELECT id, title FROM "Webinar" LIMIT 10;

# Count records
SELECT COUNT(*) FROM "User";
SELECT COUNT(*) FROM "Session";
```

---

## Troubleshooting Quick Fixes

### Redis Not Responding
```bash
# Check status
redis-cli ping

# Restart Redis
docker-compose restart redis

# Check logs
docker-compose logs redis
```

### Database Connection Error
```bash
# Verify connection
psql -U postgres -d estate_platform -c "SELECT 1"

# Check Docker
docker-compose logs postgres

# Restart database
docker-compose restart postgres
```

### Admin Setup Page Blank
```bash
# 1. Check Redis
redis-cli ping

# 2. Clear cache
redis-cli DEL "admin:setup"

# 3. Restart app
docker-compose restart web

# 4. Login again
```

### Port Already in Use
```bash
# Kill process on port 3000
lsof -i :3000
kill -9 <PID>

# Or use different port
npm run dev -- -p 3002
```

---

## Performance Testing

### Quick Performance Check
```bash
# Time first request (cache miss)
time curl http://localhost:3000/api/admin/setup

# Time second request (cache hit)
time curl http://localhost:3000/api/admin/setup

# Should be 90%+ faster
```

### Load Testing
```bash
# Install Apache Bench
brew install httpd  # macOS
apt install apache2-utils  # Linux

# Run test (100 requests, 10 concurrent)
ab -n 100 -c 10 http://localhost:3000/api/admin/setup

# Check results:
# - Requests per second (higher is better)
# - Time per request (lower is better)
```

## Cache Key Reference

```
session:{sessionId}           # User sessions (7 days)
user:{userId}                 # User profiles (1 hour)
admin:setup                   # Config (5 minutes)
webinar:{webinarId}          # Webinar data
webinars:list:{page}         # Webinar listings
registrations:{userId}       # User registrations
contact:{contactId}          # Contact forms
```

---

## Development Workflow

### Daily Development
```bash
# Start services
docker-compose up -d

# Verify Redis
redis-cli ping

# Check logs
docker-compose logs -f

# Make changes

# Restart if needed
docker-compose restart web
```

### Database Changes
```bash
# After schema changes
npm run db:generate
npm run db:migrate

# Reset database (dev only!)
npx prisma migrate reset
```

### Cache Debugging
```bash
# Monitor real-time
redis-cli MONITOR

# Make API calls
curl http://localhost:3000/api/admin/setup

# Watch cache operations
# Should see: GET admin:setup
```
