Health Check Summary

  • Platform: SQL Server Database
  • Health check category: QueryPlans

What This Health Check Means

This health check looks for design or query-pattern choices that can make execution plans harder to optimize and troubleshoot.

Why It Matters

Plan quality problems often appear as intermittent performance incidents. This check helps you find the design issue while there is time to tune it deliberately.

What To Do If It Fails

Inspect the affected code path and recent execution plans. Prefer query rewrites, indexing, statistics fixes, and application changes over broad server settings unless the workload has been tested.

Review Workflow

  1. Open the health check result and identify the affected object, execution plan, query pattern, index usage, and recent statistics history.
  2. Decide whether the condition is intentional, inherited from a legacy system, or caused by recent change.
  3. Validate the fix in a lower environment or during a safe maintenance window when the change can affect plans, storage, or access.
  4. Rerun or refresh the health check after remediation so the Mini DBA health view reflects the new state.

Evidence To Collect

Keep before-and-after evidence such as execution plans, runtime, reads, writes, and index usage so the change can be judged by workload impact rather than preference.

How To Prioritize It

Prioritize it by blast radius. Fix it quickly when it affects a production workload, a shared server, or a customer-facing service; otherwise place it in the normal improvement backlog with an owner.

Prevention And Ownership

Prevent repeat failures by adding the finding to the normal performance review cycle. Query and index checks are most useful when developers and DBAs share the same evidence and agree on the expected workload pattern.

Runbook Use

Add this page to the operational runbook for SQL Server Database environments where the check repeatedly fails. Record local thresholds, approved exceptions, escalation contacts, and the expected review interval so the next administrator can act quickly without rediscovering the same context.
