# Diagnostic Reference Guide

**Advanced Diagnostics Focus**: This guide provides comprehensive diagnostic procedures for performance monitoring, session management, and system-level troubleshooting. Use these procedures for complex issues that require deep analysis and systematic investigation.

**Systematic Investigation**: Each diagnostic section includes monitoring tools, analysis procedures, and optimization strategies to identify root causes and implement effective solutions.

## Performance Monitoring and Analysis

### System Resource Diagnostics

**Comprehensive Performance Monitoring:**
```bash
# Complete system resource analysis
echo "=== SuperClaude Performance Diagnostics ==="

# CPU usage analysis
echo "=== CPU Usage ==="
top -b -n 1 | head -10
ps aux --sort=-%cpu | head -10

# Memory usage analysis
echo "=== Memory Usage ==="
free -h
ps aux --sort=-%mem | head -10

# Disk I/O analysis
echo "=== Disk I/O ==="

df -h

# Network analysis (if MCP servers used)
echo "=== Network Status ==="
netstat -i
ss -tuln | grep -E ":8000|:8001|:8002"

# Process analysis
echo "=== SuperClaude Processes ==="
ps aux | grep -E "python.*SuperClaude|node.*mcp|claude"
```

**Real-time Performance Monitoring:**
```bash
# Continuous monitoring setup
echo "=== Setting up continuous monitoring ==="

# Install monitoring tools if needed
# Ubuntu/Debian: sudo apt install htop iotop nethogs
# CentOS/RHEL: sudo yum install htop iotop nethogs
# macOS: brew install htop

# Real-time monitoring commands
echo "Use these commands for real-time monitoring:"
echo "htop              # Interactive process monitor"
echo "iotop             # I/O usage by process"
echo "nethogs           # Network usage by process"
echo "watch free -h     # Memory usage updates"
echo "watch df -h       # Disk space updates"

# Performance baseline establishment
echo "=== Establishing performance baselines ==="

# CPU bottleneck detection
echo "CPU Analysis:"
top -b -n 1 | grep "Cpu(s)" | awk '{print $2}' | cut -d'%' -f1

   - Record exact error messages
   - Note system state when error occurs
   - Document reproduction steps

2. HYPOTHESIS: What might be causing the issue?
   - Installation problems
   - Configuration errors
   - Resource constraints
   - Environmental issues

3. TESTING: How to verify the hypothesis?
   - Isolated component testing
   - Resource monitoring during failure
   - Configuration validation
   - Dependency verification

4. RESOLUTION: How to fix the identified cause?
   - Apply targeted solutions
   - Verify fix effectiveness
   - Prevent recurrence
   - Document solution

### Systematic Problem Resolution

**Multi-Layer Diagnostic Approach:**

# Layer 1: System level
echo "Layer 1 - System Level Diagnostics:"
echo "Operating system: $(uname -a)"
echo "Available memory: $(free -h | grep Mem | awk '{print $7}')"

# Layer 2: Python environment
echo "Layer 2 - Python Environment:"
echo "Python version: $(python3 --version)"

## Emergency Procedures

### Complete System Recovery

**Full System Recovery Protocol:**
```bash
# Complete SuperClaude system recovery

# Step 5: MCP server installation (if Node.js available)
if which node >/dev/null 2>&1; then
    echo "Step 5: MCP server installation..."
    python3 -m SuperClaude install --components mcp --force

    else
        echo "⚠️ MCP server installation failed - continuing without MCP"

else
    echo "Step 5: Skipping MCP servers (Node.js not available)"

# Step 6: Verification

**Disaster Recovery Checklist:**
```bash
# Disaster recovery checklist and procedures
echo "=== Disaster Recovery Checklist ==="

cat << 'EOF'
SuperClaude Disaster Recovery Checklist:

PRE-RECOVERY ASSESSMENT:
□ Identify specific failure symptoms
□ Document error messages and conditions
□ Check system resource availability
□ Verify backup existence and integrity

RECOVERY STEPS:
□ Create system state backup
□ Stop all Claude Code sessions
□ Clear corrupted configurations
□ Perform fresh installation
□ Verify basic functionality
□ Restore custom configurations (if applicable)
□ Test core operations
□ Reinstall MCP servers (if needed)
□ Validate full functionality

POST-RECOVERY VERIFICATION:
□ Test SuperClaude version command
□ Verify configuration file integrity
□ Test basic operations in Claude Code
□ Validate MCP server functionality
□ Document recovery process and lessons learned

PREVENTION MEASURES:
□ Regular configuration backups
□ System resource monitoring
□ Update management procedures
□ Recovery procedure documentation
□ Test recovery procedures periodically
