Usage Guide

Start Continuous Monitoring

# Option 1: Foreground (see real-time output)
./scripts/system_resource_monitor.sh monitor

# Option 2: Background (runs silently)
nohup ./scripts/system_resource_monitor.sh monitor > /dev/null 2>&1 &

# Verify monitoring is running
cat /tmp/resource_monitor.pid

Check Current Status

# One-time status check with report generation
./scripts/system_resource_monitor.sh status

# View the generated report
cat SYSTEM_RESOURCE_MONITOR_REPORT.md

Stop Monitoring

./scripts/system_resource_monitor.sh stop

Generate Report

# Generate report without starting monitoring
./scripts/system_resource_monitor.sh report

View Logs

# View last 50 log entries
tail -50 system_resource_monitor.log

# View only alerts
grep -E 'ALERT|WARNING|CRITICAL' system_resource_monitor.log

# View memory timeline
grep 'Memory:' system_resource_monitor.log

# Follow logs in real-time
tail -f system_resource_monitor.log

Alert Scenarios

Scenario 1: Memory >90% (CRITICAL)

Alert Output:

🚨 MEMORY ALERT: 92% usage exceeds 90% threshold!
   Available: 2048MB
   Top 5 memory consumers:
   - rustc (PID 12345): 15.2%
   - train_liquid_dbn (PID 23456): 12.8%
   - postgres (PID 34567): 5.3%

Recommendations:

1. Kill non-essential processes (Chrome, Firefox, Slack)
2. Reduce batch size in training configuration
3. Enable gradient checkpointing
4. Use mixed precision (fp16) training

Emergency Command:

# Kill non-essential processes
pkill -f 'chrome|firefox|slack' 2>/dev/null || true

# Clear page cache (safe, no data loss)
sudo sync && sudo sh -c 'echo 3 > /proc/sys/vm/drop_caches'

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

Scenario 2: Swap >6GB (WARNING)

Alert Output:

🚨 SWAP ALERT: 6500MB usage exceeds 6144MB threshold!
   System is likely thrashing - performance severely degraded

Recommendations:

1. System is thrashing (reading from disk instead of RAM)
2. Kill largest memory consumer immediately
3. Restart training with reduced batch size

Emergency Command:

# Kill training processes
pkill -f 'train_liquid|optuna'

# Wait for swap to clear
sleep 30

# Reduce batch size and restart

Scenario 3: Disk >85% (WARNING)

Alert Output:

⚠️  DISK ALERT: 88% usage exceeds 85% threshold!
   Available: 20G

Recommendations:

1. Clean up old checkpoints
2. Remove old logs (>7 days)
3. Clean cargo cache
4. Remove Docker volumes

Cleanup Commands:

# 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

# Check space again
df -h /

Integration with ML Training

Pre-Training Setup

Before starting ML training, ensure monitoring is active:

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

# 2. Verify monitoring is running
ps aux | grep system_resource_monitor

# 3. Check initial status
./scripts/system_resource_monitor.sh status

# 4. Start training
cargo run -p ml --example train_liquid_dbn --features cuda --release

During Training

Monitor logs for alerts:

# Follow monitoring output
tail -f system_resource_monitor.log

# Check for alerts
watch -n 5 'grep -c "ALERT" system_resource_monitor.log'

Post-Training Cleanup

After training completes:

# 1. Generate final report
./scripts/system_resource_monitor.sh report

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

# 3. Archive logs
mv system_resource_monitor.log logs/training_$(date +%Y%m%d_%H%M%S).log

Optimization Recommendations

Memory Optimization

1. Batch Size Tuning:

   • Memory <50%: Increase batch size by 50%
   • Memory 50-80%: Current batch size is optimal
   • Memory >80%: Reduce batch size by 50%

2. Gradient Checkpointing:

   • Enable for MAMBA-2/TFT models if memory >70%
   • Trades 30% more compute for 50% less memory
   • Implementation: Add gradient_checkpointing=True to model config

3. Mixed Precision:

   • Use fp16 instead of fp32 to halve memory usage
   • Minimal accuracy impact (<0.5% for most models)
   • Implementation: Add --mixed-precision flag to training

Swap Optimization

1. Increase Physical RAM: If swap >2GB consistently, consider RAM upgrade
2. Reduce Batch Size: Swap usage indicates memory pressure
3. Enable zswap: Compressed swap in memory (faster than disk)

Disk Optimization

1. Checkpoint Management: Keep only last 3 epochs
2. Log Rotation: Archive logs older than 7 days
3. Cargo Cache: Clean after major builds
4. Docker Pruning: Remove unused images/volumes weekly

Troubleshooting

Issue 1: Monitoring Not Starting

Symptom: Script exits immediately

Solution:

# Check script permissions
ls -la scripts/system_resource_monitor.sh

# Make executable if needed
chmod +x scripts/system_resource_monitor.sh

# Check for errors
./scripts/system_resource_monitor.sh monitor 2>&1 | head -20

Issue 2: High False Positives

Symptom: Too many alerts for normal usage

Solution: Edit thresholds in script:

MEMORY_THRESHOLD=90  # Change to 95 for less sensitive alerts
SWAP_THRESHOLD=6144  # Change to 8192 for more tolerance
DISK_THRESHOLD=85    # Change to 90 for less frequent warnings

Issue 3: Missing Log File

Symptom: Log file not created

Solution:

# Check write permissions
touch system_resource_monitor.log
ls -la system_resource_monitor.log

# Create log directory if needed
mkdir -p logs

Issue 4: PID File Conflicts

Symptom: "Already running" error

Solution:

# Remove stale PID file
rm -f /tmp/resource_monitor.pid

# Restart monitoring
./scripts/system_resource_monitor.sh monitor
