Performance Statistics - QP Metrics

SQL Inspector > Performance Statistics - QP Metrics

Each SQL statement captured from the QP Metrics has the following performance statistics:

Statistics	Description
Execution time	How long it takes to execute the SQL statement on the CPU displayed in milliseconds.
Elapsed time	This is a total of the Execution time and the time it takes to parse, compile, and optimize the SQL statement displayed in milliseconds.
Logical IO	Total logical IO reads during the execution of the SQL statement.
Physical IO	Total physical IO reads during the execution of the SQL statement.
Execution count	Number of times the SQL statement has been executed.
Abort count	Number of times the resource governor terminated the SQL statement because a resource limit was surpassed.

The execution time, elapsed time, logical IO, and physical IO statistics each of have three values taken from the number of times the SQL statements was executed: the minimum, the maximum, and the average.

Data Directory Setting

SQL Inspector > Data Directory Setting

The SQL Inspector data directory is where the data files are created while executing the Inspect function. The data directory path is set in the Preferences window.
