A meticulous health check for your SQL Database is essential to monitor peak performance and data security.
This comprehensive assessment identifies potential issues, optimizes efficiency, and safeguards you valuable data.
Start with the checklist - What is the issue?
Are you having a downtime on your SQL Server?
Do you have slow running queries?
Are there any blocking or deadlocks?
Is there any running maintenance (backups, index fragmentation, dbcc etc.)?
Did you initiate any version upgrade of SQL Server (2008, 2012,2014, 2016, 2017 etc.)?
Any partitioning implementation?
Is the server a shared SQL Server instance?
Do you have OLTP and reporting service on the same server?
What is the previous "Baseline" state of the system?
What is the used and available memory?
Do you encounter CPU bottlenecks?
What is the status of HA/DR synchronization and components?
Do we have disk latency?
Are you having high waits?
Any automatic scheduled jobs implemented or change?
Do you have baseline for the top executing queries?
Any system change/deployment done?
Any idea about System Configuration and it's impact?
Any changes on Server, Instance and Database settings?
Is the server Physical or Virtual Machine (VM)?
Have you correctly allocated the number of sockets and logical processor in the server?
Did you correctly configure the memory?
Any volume partition alignment?
Did you consider Lock Pages in Memory and Instant File Initialization?
Have you check the Power Management?
Have you checked the BIOS settings?
Have you checked the Database settings?
How to begin with your System Health Checks?
Review and start with the system configuration.
Inspect the resource usage of CPU, Memory, Disk latency and SQL processes.
Check all the currently running processes and aggregates.
Eliminate and Pinpoint problem areas of improvement.
