This SINGLE Database Health Check is a customized service focused on delivering clear pieces of evidence about the status of your database system performance and maintenance strategy.
Our goal is to make it as easy as possible for you to understand.
After the analysis is done and presented to you, we will go over everything on the report until you run out of questions.
All of the checks are non-intrusive, very lightweight and will not affect your production SQL Server.
All data collection can be done during normal business operating hours.
This is about 90% of what will happen.
The remaining 10% will be spent on items discovered during analysis, requiring more analysis.
Here is what a database health check will check for:
