Performing a daily health check on your SQL Server 2019 can help you proactively identify potential issues and ensure the stability and performance of your database environment. Here is a checklist of tasks you can include in your daily SQL Server health check routine:
Verify Sql Server Instance Availability:
Check if the SQL Server service is running.
Ensure connectivity to the SQL Server instance.
Monitor server resource usage (CPU, memory, disk space).
Review Sql Server Error Logs:
Check the SQL Server error logs for any error messages or warnings.
Investigate and address any critical errors or recurring issues.
Monitor Database Backup Jobs:
Verify that scheduled backup jobs have been completed successfully.
Check backup files’ integrity and ensure they are accessible for restoration.
Check Database Availability And Performance:
Verify the availability and connectivity of critical databases.
Monitor database performance metrics (CPU usage, disk I/O, transaction log usage).
Identify And Investigate Any Slow-Running Queries Or Resource-Intensive Operations.
Review Sql Server Agent Jobs And Alerts:
Ensure that scheduled jobs, such as maintenance tasks or data imports, have been executed successfully.
Check for any failed jobs and investigate the cause.
Review SQL Server Agent alerts and notifications for any critical issues.
Monitor Index Fragmentation:
Check for index fragmentation using the sys.dm_db_index_physical_stats DMV.
Rebuild or reorganize fragmented indexes to improve query performance.
Evaluate Disk Space Utilization:
Monitor disk space usage for both data and log files.
Ensure that sufficient free space is available to prevent file growth issues.
Identify and address any potential disk space constraints.
Monitor Database Size And Auto-Growth Settings:
Review the size and growth settings of your databases.
Monitor database file size to prevent unexpected growth or constraints.
Validate Sql Server Security:
Review SQL Server logins and user accounts.
Check for any unauthorized or dormant accounts.
Monitor security-related events and failed login attempts.
Review Sql Server Maintenance Plans:
Verify the execution status of maintenance plans, including tasks like index rebuilds, statistics updates, and integrity checks.
Check for any failures or warnings related to maintenance tasks.
Monitor Sql Server Replication (If Applicable):
Verify the status and synchronization of replication publications and subscriptions.
Monitor replication agents for any errors or latency issues.
Stay Up-To-Date With Sql Server Patches And Updates:
Regularly check for SQL Server patches and updates released by Microsoft.
Evaluate the need for applying the latest service packs or cumulative updates.
By incorporating these tasks into your daily SQL Server health check routine, you can proactively identify and address any potential issues, ensuring the smooth operation of your SQL Server 2019 environment.
