Specify SQL filter criteria.
Notes:
- Use the cursor to hover over an option (bar) in the graph to display option details.
- Click List statistics data to display the options for the currently selected filter criterion in a grid format

Optimize Indexes immediately asks you to choose a second database connection. Select a database connection to use to retrieve execution plans and evaluate index alternatives.
Note: This step allows you to select an alternate database (other than the one used to collect SQL) to run the index optimization process. In other words, you can collect your SQL from one database, but run the optimize indexes process on a second database. The second database must have the same application environment and data volume statistics as the first.
