Troubleshooting Guide

This guide provides solutions for common issues and troubleshooting procedures for AIDDDMAP deployments.

Common Issues

1. API Issues

Connection Errors

# Check API service status
systemctl status aidddmap-api

# View API logs
tail -f /var/log/aidddmap/api.log

# Check network connectivity
curl -v https://api.aidddmap.com/health

Authentication Failures

interface AuthError {
  code: string;
  message: string;
  details: {
    token?: string;
    expiry?: Date;
    scope?: string[];
  };
}

// Common error codes
const AUTH_ERRORS = {
  INVALID_TOKEN: "Token validation failed",
  EXPIRED_TOKEN: "Token has expired",
  INSUFFICIENT_SCOPE: "Insufficient permissions",
  RATE_LIMITED: "Too many requests",
};

2. Database Issues

Connection Problems

# Check database connectivity
pg_isready -h localhost -p 5432

# View database logs
tail -f /var/log/postgresql/postgresql.log

# Check active connections
psql -c "SELECT * FROM pg_stat_activity;"

Performance Issues

-- Find slow queries
SELECT pid, age(clock_timestamp(), query_start), usename, query
FROM pg_stat_activity
WHERE query != '<IDLE>'
  AND query NOT ILIKE '%pg_stat_activity%'
ORDER BY query_start desc;

-- Check index health
SELECT schemaname, tablename, indexname,
       pg_size_pretty(pg_relation_size(indexrelid)) as index_size,
       idx_scan as index_scans
FROM pg_stat_user_indexes
ORDER BY pg_relation_size(indexrelid) DESC;

3. Memory Issues

Memory Leaks

# Check memory usage
free -m

# Monitor process memory
ps aux | grep aidddmap

# Analyze heap dumps
jmap -dump:format=b,file=heap.bin <pid>

Out of Memory

memory_monitoring:
  thresholds:
    warning: 80%
    critical: 90%

  actions:
    - dump_heap
    - restart_service
    - notify_admin

Diagnostic Tools

1. Logging

Log Configuration

interface LogConfig {
  level: "debug" | "info" | "warn" | "error";
  format: "json" | "text";
  destination: "file" | "stdout" | "both";
  rotation: {
    size: string;
    keep: number;
    compress: boolean;
  };
}

Log Analysis

# Search for errors
grep -i error /var/log/aidddmap/*.log

# Count occurrences
grep -c "OutOfMemoryError" /var/log/aidddmap/api.log

# Analyze patterns
awk '/Error/ {print $4}' /var/log/aidddmap/api.log | sort | uniq -c

2. Monitoring

Health Checks

interface HealthCheck {
  component: string;
  status: "healthy" | "degraded" | "unhealthy";
  lastCheck: Date;
  details: {
    uptime: number;
    responseTime: number;
    errorRate: number;
  };
}

Performance Metrics

metrics:
  collection:
    interval: 10s
    retention: 7d

  alerts:
    - condition: "error_rate > 0.01"
      duration: "5m"
      severity: "critical"

    - condition: "response_time_p95 > 500"
      duration: "10m"
      severity: "warning"

System Issues

1. Network Problems

Connectivity Issues

# Check DNS resolution
dig api.aidddmap.com

# Test network latency
ping -c 5 api.aidddmap.com

# Trace network path
traceroute api.aidddmap.com

# Check open ports
netstat -tulpn | grep LISTEN

SSL/TLS Issues

# Check certificate validity
openssl x509 -in /etc/ssl/certs/aidddmap.crt -text -noout

# Test SSL connection
openssl s_client -connect api.aidddmap.com:443 -servername api.aidddmap.com

# Verify certificate chain
openssl verify -CAfile /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/aidddmap.crt

2. Disk Issues

Storage Problems

# Check disk space
df -h

# Find large files
find /var/log -type f -size +100M

# Monitor IO
iostat -x 1

# Check inode usage
df -i

File Permissions

# Fix permissions
chmod -R 755 /opt/aidddmap
chown -R aidddmap:aidddmap /opt/aidddmap

# Check SELinux context
ls -Z /opt/aidddmap

# Audit file access
auditctl -w /opt/aidddmap -p warx -k aidddmap_files

Application Issues

1. Service Problems

Process Management

# Check service status
systemctl status aidddmap-*

# View service logs
journalctl -u aidddmap-api -f

# Restart service
systemctl restart aidddmap-api

# Check process resources
top -p $(pgrep -d',' -f aidddmap)

Configuration Issues

# Configuration validation
config_check:
  paths:
    - /etc/aidddmap/config.yml
    - /etc/aidddmap/api.yml
    - /etc/aidddmap/db.yml

  validators:
    - syntax
    - schema
    - connectivity
    - permissions

2. Performance Issues

Slow Requests

interface RequestTrace {
  id: string;
  path: string;
  duration: number;
  stages: {
    name: string;
    start: number;
    end: number;
    duration: number;
  }[];
}

Resource Contention

resource_monitoring:
  cpu:
    threshold: 80%
    interval: 10s

  memory:
    threshold: 85%
    interval: 30s

  disk_io:
    threshold: 90%
    interval: 1m

Security Issues

1. Access Problems

Authentication Issues

interface AuthDiagnostics {
  token: {
    valid: boolean;
    expired: boolean;
    claims: Record<string, any>;
  };
  user: {
    exists: boolean;
    active: boolean;
    permissions: string[];
  };
  request: {
    ip: string;
    headers: Record<string, string>;
    timestamp: Date;
  };
}

Authorization Failures

access_audit:
  log_level: info
  include:
    - timestamp
    - user_id
    - resource
    - action
    - decision
    - reason
  retention: 30d

2. Security Incidents

Incident Response

incident_response:
  steps:
    1: "Identify and isolate"
    2: "Assess impact"
    3: "Contain threat"
    4: "Collect evidence"
    5: "Remediate"
    6: "Report"

  contacts:
    security: security@yourdomain.com
    legal: legal@yourdomain.com

Security Scanning

# Run security scan
npm audit

# Check for vulnerabilities
trivy image aidddmap/api:latest

# Scan dependencies
snyk test

# Monitor suspicious activity
fail2ban-client status

Recovery Procedures

1. Backup Recovery

Database Recovery

# Restore from backup
pg_restore -d aidddmap backup.dump

# Point-in-time recovery
pg_basebackup -D /var/lib/postgresql/data -Fp -Xs -P

# Verify recovery
psql -c "SELECT pg_is_in_recovery();"

File Recovery

  backup_location: /backups
  retention: 30d
  verification:
    checksum: true
    test_restore: true

2. Disaster Recovery

Service Recovery

# Recovery steps
systemctl stop aidddmap-*
restore-db-from-backup latest.dump
restore-files-from-backup
verify-data-integrity
systemctl start aidddmap-*
run-health-checks

Data Verification

interface RecoveryVerification {
  database: {
    tables: string[];
    rowCounts: Record<string, number>;
    checksums: Record<string, string>;
  };
  files: {
    count: number;
    size: number;
    permissions: boolean;
  };
  services: {
    status: Record<string, boolean>;
    health: Record<string, boolean>;
  };
}
