# System Monitor

Monitor system metrics like CPU, memory, disk, and network.

## Quick Start

```bash
# Check current status
python scripts/monitor.py --status

# Monitor continuously
python scripts/monitor.py --watch
```

## Usage

```bash
python scripts/monitor.py [OPTIONS]

Options:
  --status        Show current system status
  --watch         Monitor continuously
  --interval SECS Check interval (default: 5)
  --cpu           Show CPU usage
  --memory        Show memory usage
  --disk          Show disk usage
  --network       Show network stats
  --processes     Show top processes
  --alert VALUE   Alert threshold (e.g., cpu:90)
  --json          Output as JSON
```

## Examples

```bash
# Quick status check
python scripts/monitor.py --status

# Watch mode
python scripts/monitor.py --watch --interval 10

# Alert on high CPU
python scripts/monitor.py --watch --alert cpu:90

# Alert on low disk
python scripts/monitor.py --watch --alert disk:90

# JSON output for dashboards
python scripts/monitor.py --status --json
```

## Alert Examples

```bash
# CPU above 90%
python scripts/monitor.py --watch --alert cpu:90

# Memory above 80%
python scripts/monitor.py --watch --alert memory:80

# Disk above 85%
python scripts/monitor.py --watch --alert disk:85
```

## Metrics

- CPU usage per core
- Memory usage (used/free/total)
- Disk usage per partition
- Network I/O
- Top processes by CPU/memory
- Uptime
