Description of the illustration sql_diagram.png

The image shows a line chart titled Unique SQL statements that tracks the number of unique SQL statements collected over time.

An information icon appears next to the chart title. A tooltip is displayed with the following explanation:

When the number of unique SQL statements drops to zero, you may stop collecting. Zero indicates that the firewall is no longer seeing new unique SQL statements, meaning you have collected all unique SQL statements.
