The Top Databases report identifies your worst performing SQL Server databases based on the size of the database, the growth rate of the database, and the number of reads, writes, and transactions per second performed on the database.

You can further filter your monitored databases by wait time with waits that exceed a defined Wait Threshold in milliseconds. Use this report to compile a list of databases that used most often or have the heaviest loads.

You can use % as a wildcard in the Search Value field.

When to run this report

You should run the Top Databases report on a routine basis, such as once a week. This report helps you:

  • Plan for upcoming maintenance
  • Identify issues that may impact third-party application performance even though the host SQL Server instance remains healthy
  • Compare database performance across your enterprise
