Enterprise Log Analysis

Analyze system logs for troubleshooting, monitoring, and security analysis.

Context

  • Recent system logs: !journalctl --no-pager -n 100 --since "1 hour ago"
  • Application logs: !tail -n 50 /var/log/application.log 2>/dev/null || echo "Application logs not found"
  • Error logs: !grep -i error /var/log/syslog 2>/dev/null | tail -20 || echo "No recent errors found"
  • Security logs: !grep -i "failed\|denied\|unauthorized" /var/log/auth.log 2>/dev/null | tail -10 || echo "No security events found"
  • Web server logs: !tail -n 20 /var/log/nginx/access.log 2>/dev/null || tail -n 20 /var/log/apache2/access.log 2>/dev/null || echo "Web server logs not found"
