Supported actions are:\n * snapshot      Store a snapshot. The default is to make a snapshot of the current content of\n performance_schema.events_statements_summary_by_digest, but by setting in_table\n this can be overwritten to copy the content of the specified table.\n The snapshot is stored in the sys.tmp_digests temporary table.\n * overall       Generate analyzis based on the content specified by in_table. For the overall analyzis,\n in_table can be NOW() to use a fresh snapshot. This will overwrite an existing snapshot.\n Use NULL for in_table to use the existing snapshot. If in_table IS NULL and no snapshot\n exists, a new will be created.\n See also in_views and @sys.statement_performance_analyzer.limit.\n * delta         Generate a delta analysis. The delta will be calculated between the reference table in\n in_table and the snapshot. An existing snapshot must exist.\n The action uses the sys.tmp_digests_delta temporary table.\n See also in_views and @sys.statement_performance_analyzer.limit.\n * create_table  Create a regular table suitable for storing the snapshot for later use, e.g. for\n calculating deltas.\n * create_tmp    Create a temporary table suitable for storing the snapshot for later use, e.g. for\n calculating deltas.\n * save          Save the snapshot in the table specified by in_table. The table must exists and have\n the correct structure.\n If no snapshot exists, a new is created.\n * cleanup       Remove the temporary tables used for the snapshot and delta.\n \n in_table (VARCHAR(129)):\n The table argument used for some actions. Use the format ''db1.t1'' or ''t1'' without using any backticks (`)\n for quoting. Periods (.) are not supported in the database and table names.\n \n The meaning of the table for each action supporting the argument is:\n \n * snapshot      The snapshot is created based on the specified table. Set to NULL or NOW() to use\n the current content of performance_schema.events_statements_summary_by_digest.\n * overall       The table with the content to create the overall analyzis for. The following values\n can be used:\n - A table name - use the content of that table.\n - NOW()        - create a fresh snapshot and overwrite the existing snapshot.\n - NULL         - use the last stored snapshot.\n * delta         The table name is mandatory and specified the reference view to compare the currently\n stored snapshot against. If no snapshot exists, a new will be created.\n * create_table  The name of the regular table to create.\n * create_tmp    The name of the temporary table to create.\n * save          The name of the table to save the currently stored snapshot into.\n \n in_views (SET (''with_runtimes_in_95th_percentile'', ''analysis'', ''with_errors_or_warnings'',\n ''with_full_table_scans'', ''with_sorting'', ''with_temp_tables'', ''custom''))\n Which views to include:  * with_runtimes_in_95th_percentile  Based on the sys.statements_with_runtimes_in_95th_percentile view * analysis                          Based on the sys.statement_analysis view * with_errors_or_warnings           Based on the sys.statements_with_errors_or_warnings view * with_full_table_scans             Based on the sys.statements_with_full_table_scans view * with_sorting                      Based on the sys.statements_with_sorting view * with_temp_tables                  Based on the sys.statements_with_temp_tables view * custom                            Use a custom view. This view must be specified in @sys.statement_performance_analyzer.view to an existing view or a query  Default is to include all except ''custom''.   Configuration Options  sys.statement_performance_analyzer.limit The maximum number of rows to include for the views that does not have a built-in limit (e.g. the 95th percentile view). If not set the limit is 100.  sys.statement_performance_analyzer.view Used together with the ''custom'' view. If the value contains a space, it is considered a query, otherwise it must be an existing view querying the performance_schema.events_statements_summary_by_digest table. There cannot be any limit clause including in the query or view definition if @sys.statement_performance_analyzer.limit > 0. If specifying a view, use the same format as for in_table.  sys.debug Whether to provide debugging output. Default is ''OFF''. Set to ''ON'' to include.   Example  To create a report with the queries in the 95th percentile since last truncate of performance_schema.events_statements_summary_by_digest and the delta for a 1 minute period:  1. Create a temporary table to store the initial snapshot. 2. Create the initial snapshot. 3. Save the initial snapshot in the temporary table. 4. Wait one minute. 5. Create a new snapshot. 6. Perform analyzis based on the new snapshot. 7. Perform analyzis based on the delta between the initial and new snapshots.  mysql> CALL sys.statement_performance_analyzer(''create_tmp'', ''mydb.tmp_digests_ini'', NULL); Query OK, 0 rows affected (0.08 sec)  mysql> CALL sys.statement_performance_analyzer(''snapshot'', NULL, NULL); Query OK, 0 rows affected (0.02 sec)  mysql> CALL sys.statement_performance_analyzer(''save'', ''mydb.tmp_digests_ini'', NULL); Query OK, 0 rows affected (0.00 sec)  mysql> DO SLEEP(60); Query OK, 0 rows affected (1 min 0.00 sec)  mysql> CALL sys.statement_performance_analyzer(''snapshot'', NULL, NULL); Query OK, 0 rows affected (0.02 sec)  mysql> CALL sys.statement_performance_analyzer(''overall'', NULL, ''with_runtimes_in_95th_percentile''); +-----------------------------------------+ | Next Output                             | +-----------------------------------------+ | Queries with Runtime in 95th Percentile | +-----------------------------------------+ 1 row in set (0.05 sec)  ...  mysql> CALL sys.statement_performance_analyzer(''delta'', ''mydb.tmp_digests_ini'', ''with_runtimes_in_95th_percentile''); +-----------------------------------------+ | Next Output                             | +-----------------------------------------+ | Queries with Runtime in 95th Percentile | +-----------------------------------------+ 1 row in set (0.03 sec)  ...
