Performing a Comprehensive SQL Server Database Health Audit

When people think about their SQL Server instance and databases, they might just focus on ensuring the data inside is correct and hope the tables and pages that comprise the database are in good shape. Some even go as far as to enable basic maintenance jobs with backups, corruption checks, and indexing. While that’s a good start, maintaining a database that is secure and performant requires a deeper and more thorough audit.

Beyond the Basics: Delving Deeper into Database Health

A healthy SQL Server database is more than just intact tables and timely backups. Here are key areas that should be included in a comprehensive health audit:

1. Login/User Rights:
   Ensuring that login and user rights are properly configured is crucial. Overly permissive access can lead to security vulnerabilities, while restrictive access can hamper productivity. Regularly review who has access to your databases and adjust permissions as necessary.
2. Index Optimization:
   While basic indexing is essential, it’s not enough to simply add indexes and forget about them. Regularly analyze your index usage to identify missing indexes, redundant indexes, and those that are never used. Too many indexes can slow down write operations, while too few can degrade read performance. Balance is key.
3. Maintenance Jobs:
   Basic maintenance jobs such as backups and integrity checks are fundamental. However, ensure these jobs are running as expected and verify their outcomes. It’s not uncommon to find failed jobs that went unnoticed, leaving your database at risk.
4. Server Settings and Configuration:
   SQL Server offers a plethora of configuration settings that can significantly impact performance and security. Regularly review these settings to ensure they align with best practices and your specific workload requirements. Pay attention to settings like max memory, max degree of parallelism (MAXDOP), and others.
5. Performance Monitoring and Tuning:
   Utilize performance monitoring tools to identify bottlenecks. Look for slow-running queries, high resource-consuming processes, and other performance issues. Address these proactively to ensure your server runs smoothly.
6. Licensing:
   Don’t overlook licensing during your audit. Ensure that your SQL Server instance is properly licensed and that you’re not inadvertently violating any terms. Plus inadequate licensing can limit resources such as CPU.

A comprehensive SQL Server database health audit goes beyond the basics of data correctness and maintenance jobs. By taking a closer look at login/user rights, index optimization, maintenance jobs, server settings, performance monitoring, and licensing, you can ensure that your databases are not only healthy but also secure and performant.

Remember, a well-maintained database is the backbone of any application. Don’t just hope everything is fine—know it is by performing regular, in-depth health audits.
