## Scaling Procedures

### Horizontal Scaling (Add More Workers)

**When to Scale**:

- CPU utilization > 80% for 10+ minutes
- Worker pool queue depth > 100
- Response time p95 > 1000ms

```bash
#!/bin/bash
# scale_horizontal.sh

POOL_ID=$1
TARGET_WORKERS=$2

if [ -z "$POOL_ID" ] || [ -z "$TARGET_WORKERS" ]; then
    echo "Usage: $0 <pool_id> <target_workers>"
    exit 1
fi

echo "Scaling pool ${POOL_ID} to ${TARGET_WORKERS} workers..."

# 1. Get current worker count
CURRENT_WORKERS=$(mahavishnu pool list | grep "$POOL_ID" | awk '{print $3}')
echo "Current workers: ${CURRENT_WORKERS}"

# 2. Scale pool
mahavishnu pool scale "$POOL_ID" --target "$TARGET_WORKERS"

# 3. Verify new worker count
sleep 10
NEW_WORKERS=$(mahavishnu pool list | grep "$POOL_ID" | awk '{print $3}')
echo "New workers: ${NEW_WORKERS}"

# 4. Monitor health
mahavishnu pool health
```

**Usage**:

```bash
# Scale local pool to 10 workers
./scale_horizontal.sh local 10

# Scale delegated pool to 5 workers
./scale_horizontal.sh delegated 5
```

### Vertical Scaling (Increase Resources)

**When to Scale**:

- Memory utilization > 80% consistently
- Database locks increasing
- Disk I/O at capacity

```bash
# 1. Current resource limits
systemctl show mahavishnu-mcp | grep MemoryLimit
systemctl show mahavishnu-mcp | grep CPUQuota

# 2. Edit systemd service file
sudo nano /etc/systemd/system/mahavishnu-mcp.service

# Update:
# [Service]
# MemoryLimit=8G  # Increase from 4G
# CPUQuota=400%   # Increase from 200%

# 3. Reload systemd and restart service
sudo systemctl daemon-reload
sudo systemctl restart mahavishnu-mcp

# 4. Verify new limits
systemctl show mahavishnu-mcp | grep MemoryLimit
systemctl show mahavishnu-mcp | grep CPUQuota
```

______________________________________________________________________

## Log Rotation and Cleanup

**Schedule**: Daily (automatic via logrotate)

### Configuration

    sharedscripts
    postrotate
        systemctl reload mahavishnu-mcp > /dev/null 2>&1 || true
    endscript
}
```

### Manual Log Cleanup

```bash
#!/bin/bash
# cleanup_old_logs.sh

echo "=== Log Cleanup ==="
echo "Date: $(date)"
echo ""

# 1. Compress logs older than 7 days
echo "[1/3] Compressing old logs..."

# 2. Analyze query patterns
# - Look for N+1 queries
# - Check for missing indexes
# - Identify full table scans

# 3. Add indexes as needed
