## Usage Guide

### Quick Start

```bash
# Start monitoring in background
nohup ./scripts/system_resource_monitor.sh monitor > /dev/null 2>&1 &

# Check status
./scripts/system_resource_monitor.sh status

# View report
cat SYSTEM_RESOURCE_MONITOR_REPORT.md

# Stop monitoring
./scripts/system_resource_monitor.sh stop
```

### Integration with ML Training

```bash
# STEP 1: Start monitoring before training
nohup ./scripts/system_resource_monitor.sh monitor > /dev/null 2>&1 &

# STEP 2: Start ML training
cargo run -p ml --example train_liquid_dbn --features cuda --release

# STEP 3: Monitor during training (in separate terminal)
tail -f system_resource_monitor.log

# STEP 4: After training completes
./scripts/system_resource_monitor.sh report
./scripts/system_resource_monitor.sh stop
```

### Viewing Logs

```bash
# Last 50 entries
tail -50 system_resource_monitor.log

# Only alerts
grep 'ALERT' system_resource_monitor.log

# Memory timeline
grep 'Memory:' system_resource_monitor.log

# Follow real-time
tail -f system_resource_monitor.log
```

---

## Alert System

### Alert Thresholds

```yaml
memory_threshold: 90%    # CRITICAL alert
swap_threshold: 6144MB   # WARNING alert
disk_threshold: 85%      # WARNING alert
check_interval: 60s      # Check frequency
```

### Alert Levels

**🟢 GREEN (OK)**: All resources within normal ranges
- Memory <75%
- Swap <4GB
- Disk <70%

**🟡 YELLOW (WARNING)**: Resources approaching thresholds
- Memory 75-90%
- Swap 4-6GB
- Disk 70-85%

**🔴 RED (CRITICAL)**: Resources exceeded thresholds
- Memory >90%
- Swap >6GB
- Disk >85%

### Emergency Procedures

**Memory >90%**:
```bash
# 1. Kill non-essential processes
pkill -f 'chrome|firefox|slack' 2>/dev/null || true

# 2. Clear page cache (safe)
sudo sync && sudo sh -c 'echo 3 > /proc/sys/vm/drop_caches'

# 3. Emergency: Kill largest consumer
kill -9 $(ps aux --sort=-%mem | awk 'NR==2 {print $2}')
```

**Swap >6GB**:
```bash
# System is thrashing - immediate action
pkill -f 'train_liquid|optuna'
sleep 30
# Reduce batch size and restart
```

**Disk >85%**:
```bash
# Clean old checkpoints
rm -rf ml/tuning_checkpoints/trial_*/checkpoint_epoch_*

# Remove old logs
find . -name '*.log' -mtime +7 -delete

# Clean cargo cache
cargo clean
```

## Recommendations for Next Agent

### Immediate Actions

1. **Review monitoring output**: Check `SYSTEM_RESOURCE_MONITOR_REPORT.md`
2. **Verify alerts**: Ensure no critical alerts before starting work
3. **Start monitoring**: If running ML training, start background monitoring

### Integration Steps

```bash
# Before starting ML training:
./scripts/system_resource_monitor.sh status     # Check current state
nohup ./scripts/system_resource_monitor.sh monitor > /dev/null 2>&1 &

# During ML training:
tail -f system_resource_monitor.log             # Watch for alerts

# After ML training:
./scripts/system_resource_monitor.sh report     # Generate final report
./scripts/system_resource_monitor.sh stop       # Stop monitoring
```

### Troubleshooting

If monitoring issues occur:

1. **Check script permissions**: `ls -la scripts/system_resource_monitor.sh`
2. **View script errors**: `./scripts/system_resource_monitor.sh status 2>&1`
3. **Check PID file**: `cat /tmp/resource_monitor.pid`
4. **Remove stale PID**: `rm -f /tmp/resource_monitor.pid`

---

## Known Limitations

1. **Linux-only**: Relies on `free`, `df`, `ps` commands
2. **60-second granularity**: May miss brief spikes
3. **No GPU monitoring**: Only CPU/RAM/disk (GPU metrics in Wave 152)
4. **No historical graphs**: Text-based only (Grafana integration in Phase 2)
5. **No email alerts**: Console/log only (email in Phase 2)

---

## Future Enhancements (Phase 2+)

1. **Prometheus Integration**: Export metrics for Grafana
2. **GPU Monitoring**: Add NVIDIA GPU metrics
3. **Predictive Alerts**: Warn before thresholds exceeded
4. **Email/Slack Alerts**: Remote notifications
5. **Historical Analysis**: Trend analysis and capacity planning
6. **Auto-Scaling**: Automatically adjust batch size
7. **Cloud Integration**: Trigger cloud GPU provisioning
