# 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

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

# STEP 2: Start ML training

Viewing Logs

# 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

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%:

# 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:

# System is thrashing - immediate action
pkill -f 'train_liquid|optuna'
sleep 30
# Reduce batch size and restart

Disk >85%:

# 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

# 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
