Gu

Gu is Datab's preview monitoring and protection service for node health, security, backup, and audit signals. Coverage varies by deployment. HQ aggregation, alert routing, and recovery verification are being developed; disruptive actions require institutional approval.

Current runtime design

• Runs as datab-app.gu on 127.0.0.1:11445.
• Wraps Wazuh Agent (when installed) for security signals.
• Wraps Prometheus exporters (when installed) for system metrics.
• Falls back to /proc-based metrics when neither is present.

What Gu requires approval for

• Node lock mode.
• App suspension or container shutdown.
• Process termination or network isolation.
• Remote-support session approval.
• Credential / session revocation, firewall changes.

Gu is a conservative immune system, not a destructive auto-remediator. Disruptive actions are recommended; admins act.
