Slow Query Log Page

The Slow Query Log page displays a table where each row represents a SQL query that took too long to complete.

To open the Slow Query Log page

  1. Select the Spotlight on MySQL connection in the Spotlight Browser.
  2. Click Activity | Slow Query Log.

Slow Query Log entries

Note: The Slow Query Log is populated only in MySQL 5.1.12 and later.

Database variables that govern the behavior of the Slow Query Log are:

long_query_time

A "slow" SQL query is one that takes longer than long_query_time seconds to complete. The default value is 10.

slow_query_log

Enable or disable the Slow Query Log (ON or OFF).

slow_query_log_file

The name of the log file.

Note: Spotlight displays the current values for these variables in the Configuration Page of the Activity drilldown.
