Creating a SQL Insights Task

Scenarios

SQL Insights allows you to query all executed SQL statements, analyze and search for the tables that are accessed and updated most frequently, and identify SQL statements that have the longest lock wait, helping you quickly locate exceptions.

Constraints

• You need to enable Collect All Query Logs before using SQL Insights. Collecting all query logs will reduce instance performance by up to 5%.
• After Collect All Query Logs is disabled, new SQL statements will not be collected anymore and the collected SQL data will be deleted.
• Some data cannot be recorded if a buffer overrun occurs.
• If the length of a SQL statement exceeds the value of rds_sql_tracer_max_record_size, the statement is not recorded by default.

  To configure the parameter value, see Modifying Parameters of a DB Instance.

• After Collect All Query Logs is enabled, the SQL text following FROM in prepared statements is omitted (the statements are displayed as PREPARE xxx FROM ...).
