Description
Takes a raw file path, and attempts to extract the schema name from it.
Useful for when interacting with Performance Schema data
concerning IO statistics, for example.
Currently relies on the fact that a table data file will be within a
specified database directory (will not work with partitions or tables
that specify an individual DATA_DIRECTORY).
Parameters
path (VARCHAR(512)):
The full file path to a data file to extract the schema name from.
Returns
VARCHAR(64)
Example
mysql> SELECT sys.extract_schema_from_file_name('/var/lib/mysql/employees/employee.ibd');
+----------------------------------------------------------------------------+
| sys.extract_schema_from_file_name('/var/lib/mysql/employees/employee.ibd') |

Description
Takes a raw path value, and strips out the datadir or tmpdir
replacing with @@datadir and @@tmpdir respectively.
Also normalizes the paths across operating systems, so backslashes
on Windows are converted to forward slashes
Parameters
path (VARCHAR(512)):
The raw file path value to format.
Returns
VARCHAR(512) CHARSET UTF8

Description
Formats a normalized statement, truncating it if it is > 64 characters long by default.
To configure the length to truncate the statement to by default, update the `statement_truncate_len`
variable with `sys_config` table to a different value. Alternatively, to change it just for just
your particular session, use `SET @sys.statement_truncate_len := <some new value>`.
Useful for printing statement related data from Performance Schema from
the command line.
Parameters
statement (LONGTEXT):
The statement to format.
Returns
LONGTEXT

Description
Outputs a JSON formatted stack of all statements, stages and events
within Performance Schema for the specified thread.
Parameters
thd_id (BIGINT UNSIGNED):
The id of the thread to trace. This should match the thread_id
column from the performance_schema.threads table.
in_verbose (BOOLEAN):
Include file:lineno information in the events.
Example
(line separation added for output)

Description
Returns a JSON object with info on the given threads current transaction,
and the statements it has already executed, derived from the
performance_schema.events_transactions_current and
performance_schema.events_statements_history tables (so the consumers
for these also have to be enabled within Performance Schema to get full
data in the object).
When the output exceeds the default truncation length (65535), a JSON error
object is returned, such as:
{ "error": "Trx info truncated: Row 6 was cut by GROUP_CONCAT()" }
Similar error objects are returned for other warnings/and exceptions raised
when calling the function.
The max length of the output of this function can be controlled with the
ps_thread_trx_info.max_length variable set via sys_config, or the
@sys.ps_thread_trx_info.max_length user variable, as appropriate.
Parameters
in_thread_id (BIGINT UNSIGNED):
The id of the thread to return the transaction info for.

END
Description
Returns the value for the requested variable using the following logic:
1. If the option exists in sys.sys_config return the value from there.
2. Else fall back on the provided default value.
Notes for using sys_get_config():
* If the default value argument to sys_get_config() is NULL and case 2. is reached, NULL is returned.
It is then expected that the caller is able to handle NULL for the given configuration option.
* The convention is to name the user variables @sys.<name of variable>. It is <name of variable> that
is stored in the sys_config table and is what is expected as the argument to sys_get_config().
* If you want to check whether the configuration option has already been set and if not assign with
the return value of sys_get_config() you can use IFNULL(...) (see example below). However this should
not be done inside a loop (e.g. for each row in a result set) as for repeated calls where assignment
is only needed in the first iteration using IFNULL(...) is expected to be significantly slower than
using an IF (...) THEN ... END IF; block (see example below).
Parameters
in_variable_name (VARCHAR(128)):
The name of the config option to return the value for.
in_default_value (VARCHAR(128)):
The default value to return if the variable does not exist in sys.sys_config.
Returns
VARCHAR(128)

Description
Takes the query in the argument and executes it using a prepared statement. The prepared statement is deallocated,
so the procedure is mainly useful for executing one off dynamically created queries.
The sys_execute_prepared_stmt prepared statement name is used for the query and is required not to exist.
Parameters
in_query (longtext CHARACTER SET UTF8):
The query to execute.
Configuration Options
sys.debug
Whether to provide debugging output.
Default is 'OFF'. Set to 'ON' to include.

Description
Create a report of the current status of the server for diagnostics purposes. 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.
Example
To create a report and append it to the file diag.out:
mysql> TEE diag.out;
mysql> CALL sys.diagnostics(120, 30, 'current');
...
mysql> NOTEE;

Description
Takes a source database name and synonym name, and then creates the
synonym database with views that point to all of the tables within
the source database.
Useful for creating a "ps" synonym for "performance_schema",
or "is" instead of "information_schema", for example.
Parameters
in_db_name (VARCHAR(64)):
The database name that you would like to create a synonym for.
in_synonym (VARCHAR(64)):
The database synonym name.
Example
mysql> SHOW DATABASES;
+--------------------+

Description
Dumps all data within Performance Schema for an instrumented thread,
to create a DOT formatted graph file.
Each resultset returned from the procedure should be used for a complete graph
Requires the SUPER privilege for "SET sql_log_bin = 0;".
Parameters
in_thread_id (BIGINT UNSIGNED):
The thread that you would like a stack trace for
in_outfile (VARCHAR(255)):
The filename the dot file will be written to
in_max_runtime (DECIMAL(20,2)):
The maximum time to keep collecting data.
Use NULL to get the default which is 60 seconds.
in_interval (DECIMAL(20,2)):
How long to sleep between data collections.
Use NULL to get the default which is 1 second.
in_start_fresh (BOOLEAN):
Whether to reset all Performance Schema data before tracing.
in_auto_setup (BOOLEAN):
Whether to disable all other threads and enable all consumers/instruments.
This will also reset the settings at the end of the run.
in_debug (BOOLEAN):
Whether you would like to include file:lineno in the graph
Example
mysql> CALL sys.ps_trace_thread(25, CONCAT('/tmp/stack-', REPLACE(NOW(), ' ', '-'), '.dot'), NULL, NULL, TRUE, TRUE, TRUE);

Description
Traces all instrumentation within Performance Schema for a specific
Statement Digest.
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.

Description
Saves the current configuration of Performance Schema,
so that you can alter the setup for debugging purposes,
but restore it to a previous state.
Use the companion procedure - ps_setup_reload_saved(), to
restore the saved config.
The named lock "sys.ps_setup_save" is taken before the
current configuration is saved. If the attempt to get the named
lock times out, an error occurs.
The lock is released after the settings have been restored by
calling ps_setup_reload_saved().
Requires the SUPER privilege for "SET sql_log_bin = 0;".
Parameters
in_timeout INT
The timeout in seconds used when trying to obtain the lock.
A negative timeout means infinite timeout.

Description
Create a report of the statements running on the server.
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.

Description
Tests whether the table specified in in_db and in_table exists either as a regular
table, or as a temporary table. The returned value corresponds to the table that
will be used, so if there's both a temporary and a permanent table with the given
name, then 'TEMPORARY' will be returned.
Parameters
in_db (VARCHAR(64)):
The database name to check for the existence of the table in.
in_table (VARCHAR(64)):
The name of the table to check the existence of.
out_exists ENUM('', 'BASE TABLE', 'VIEW', 'TEMPORARY'):
The return value: whether the table exists. The value is one of:
* '' - the table does not exist neither as a base table, view, sequence nor temporary table.
* 'BASE TABLE' - the table name exists as a permanent base table table.
* 'VIEW' - the table name exists as a view.
* 'TEMPORARY' - the table name exists as a temporary table.
* 'SEQUENCE' - the table name exists as a sequence.
* 'SYSTEM VIEW' - the table name exists as a system view.
