Book a 1 hour time with us to review one SQL Server instance. We will send you a link to our tool that you run from your laptop. Send the results back at least one business day before the call.
Ideally, your SQL Server will have been up for at least 7 days.
This works best on VMs, on-prem and cloud VMs. Amazon RDS, Azure SQLDB and Managed Instances only give a subset of info.
