Data collected includes (some items depends on versions and settings): * The GLOBAL VARIABLES * Several sys schema views including metrics or equivalent (depending on version and settings) * Queries in the 95th percentile * Several ndbinfo views for MySQL Cluster * Replication (both master and slave) information. Some of the sys schema views are calculated as initial (optional), overall, delta: * The initial view is the content of the view at the start of this procedure. This output will be the same as the the start values used for the delta view. The initial view is included if @sys.diagnostics.include_raw = ''ON''. * The overall view is the content of the view at the end of this procedure. This output is the same as the end values used for the delta view. The overall view is always included. * The delta view is the difference from the beginning to the end. Note that for min and max values they are simply the min or max value from the end view respectively, so does not necessarily reflect the minimum/maximum value in the monitored period. Note: except for the metrics views the delta is only calculation between the first and last outputs. Requires the SUPER privilege for "SET sql_log_bin = 0;". Versions supported: * MySQL 5.6: 5.6.10 and later * MySQL 5.7: 5.7.9 and later Parameters in_max_runtime (INT UNSIGNED): The maximum time to keep collecting data. Use NULL to get the default which is 60 seconds, otherwise enter a value greater than 0. in_interval (INT UNSIGNED): How long to sleep between data collections. Use NULL to get the default which is 30 seconds, otherwise enter a value greater than 0. in_auto_config (ENUM(''current'', ''medium'', ''full'')) Automatically enable Performance Schema instruments and consumers. NOTE: The more that are enabled, the more impact on the performance. Supported values are: * current - use the current settings. * medium - enable some settings. * full - enables all settings. This will have a big impact on the performance - be careful using this option. If another setting the ''current'' is chosen, the current settings are restored at the end of the procedure. Configuration Options sys.diagnostics.allow_i_s_tables Specifies whether it is allowed to do table scan queries on information_schema.TABLES. This can be expensive if there are many tables. Set to ''ON'' to allow, ''OFF'' to not allow. Default is ''OFF''. sys.diagnostics.include_raw Set to ''ON'' to include the raw data (e.g. the original output of "SELECT * FROM sys.metrics"). Use this to get the initial values of the various views. Default is ''OFF''. sys.statement_truncate_len How much of queries in the process list output to include. Default is 64. sys.debug Whether to provide debugging output. Default is ''OFF''. Set to ''ON'' to include.

When finding a statement of interest within the performance_schema.events_statements_summary_by_digest table, feed the DIGEST MD5 value in to this procedure, set how long to poll for, and at what interval to poll, and it will generate a report of all statistics tracked within Performance Schema for that digest for the interval. It will also attempt to generate an EXPLAIN for the longest running example of the digest during the interval. Note this may fail, as: * Performance Schema truncates long SQL_TEXT values (and hence the EXPLAIN will fail due to parse errors) * the default schema is sys (so tables that are not fully qualified in the query may not be found) * some queries such as SHOW are not supported in EXPLAIN.

The views are calculated based on the overall and/or delta activity. Requires the SUPER privilege for "SET sql_log_bin = 0;". Parameters in_action (ENUM(''snapshot'', ''overall'', ''delta'', ''create_tmp'', ''create_table'', ''save'', ''cleanup'')): The action to take. Supported actions are: * snapshot Store a snapshot. The default is to make a snapshot of the current content of performance_schema.events_statements_summary_by_digest, but by setting in_table this can be overwritten to copy the content of the specified table. The snapshot is stored in the sys.tmp_digests temporary table. * overall Generate analyzis based on the content specified by in_table. For the overall analyzis, in_table can be NOW() to use a fresh snapshot. This will overwrite an existing snapshot. Use NULL for in_table to use the existing snapshot. If in_table IS NULL and no snapshot exists, a new will be created. See also in_views and @sys.statement_performance_analyzer.limit. * delta Generate a delta analysis. The delta will be calculated between the reference table in in_table and the snapshot. An existing snapshot must exist. The action uses the sys.tmp_digests_delta temporary table. See also in_views and @sys.statement_performance_analyzer.limit. * create_table Create a regular table suitable for storing the snapshot for later use, e.g. for calculating deltas. * create_tmp Create a temporary table suitable for storing the snapshot for later use, e.g. for calculating deltas. * save Save the snapshot in the table specified by in_table. The table must exists and have the correct structure. If no snapshot exists, a new is created. * cleanup Remove the temporary tables used for the snapshot and delta. in_table (VARCHAR(129)): The table argument used for some actions. Use the format ''db1.t1'' or ''t1'' without using any backticks (`) for quoting. Periods (.) are not supported in the database and table names. The meaning of the table for each action supporting the argument is: * snapshot The snapshot is created based on the specified table. Set to NULL or NOW() to use the current content of performance_schema.events_statements_summary_by_digest. * overall The table with the content to create the overall analyzis for. The following values can be used: - A table name - use the content of that table. - NOW() - create a fresh snapshot and overwrite the existing snapshot. - NULL - use the last stored snapshot. * delta The table name is mandatory and specified the reference view to compare the currently stored snapshot against. If no snapshot exists, a new will be created. * create_table The name of the regular table to create. * create_tmp The name of the temporary table to create. * save The name of the table to save the currently stored snapshot into. in_views (SET (''with_runtimes_in_95th_percentile'', ''analysis'', ''with_errors_or_warnings'', ''with_full_table_scans'', ''with_sorting'', ''with_temp_tables'', ''custom'')) 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) ...

New values were the same as original values It is not possible to log this statement The event was corrupt, leading to illegal data being read The table is of a new format not supported by this version The event could not be processed.

Incompatible key or row definition between the MariaDB .frm file and the information in the storage engine. You may have retry or dump and restore the table to fix this Too many words in a FTS phrase or proximity search Table encrypted but decryption failed. This could be because correct encryption management plugin is not loaded, used encryption key is not available or encryption method does not match. Foreign key cascade delete/update exceeds max depth Tablespace is missing for a table Sequence values are conflicting Cannot initialize encryption.
