Troubleshooting

Common Issues

Q: Events missing from audit log A:

  • Check if event was properly triggered
  • Verify queue processing status
  • Review retention policies
  • Check for filtering in current view

Q: High queue latency A:

  • Monitor queue size and processing rate
  • Check for system resource constraints
  • Review recent code deployments
  • Consider scaling queue workers

Q: Alert fatigue A:

  • Adjust alert thresholds
  • Implement alert grouping
  • Use machine learning for anomaly detection
  • Schedule alerts for business hours only
