description: Performs a comprehensive health check of a CockroachDB cluster. Gathers deployment context first, then provides tier-appropriate diagnostics. Self-Hosted uses SQL against node-level system tables and CLI. Advanced/BYOC use Cloud Console and SQL with node visibility. Standard monitors provisioned compute and workload via Cloud Console. Basic monitors Request Unit consumption and connectivity. Use for daily checks, pre-maintenance validation, post-incident verification, or production readiness assessment.
compatibility: Self-Hosted requires SQL access with admin or VIEWCLUSTERMETADATA privilege. Advanced/BYOC require Cloud Console and SQL connectivity. Standard requires Cloud Console and SQL. Basic requires Cloud Console.

Performs a comprehensive health check of a CockroachDB cluster. Before running diagnostics, this skill gathers deployment context to provide the right queries and tools for the operator's tier.

## When to Use This Skill

- Daily or shift-start operational health checks
- Before starting maintenance (Self-Hosted, Advanced, BYOC)
- After incidents to confirm recovery
- Verifying production readiness
- Monitoring capacity and performance
