build_prefix()

static int build_prefix ( const LEX_CSTRING *  prefix, const char *  category, char *  output, size_t *  output_length  )

static

Build the prefix name of a class of instruments in a category.

For example, this function builds the string 'wait/sync/mutex/sql/' from a prefix 'wait/sync/mutex' and a category 'sql'. This prefix is used later to build each instrument name, such as 'wait/sync/mutex/sql/LOCK_open'.

Parameters

	prefix	Prefix for this class of instruments
	category	Category name
[out]	output	Buffer of length PFS_MAX_INFO_NAME_LENGTH.
[out]	output_length	Length of the resulting output string.

Returns

0 for success, non zero for errors

This is the entry point to the performance schema statement instrumentation.

This instrumentation is used to:

• provide data to the performance schema tables, according to the performance schema configuration,
• provide data to the telemetry traces component, if present, according to the telemetry component configuration.

These two data paths are executed in parallel, based on data collected once, and possibly used twice for different purposes.

struct PSI_statement_locker_state 

is used to collect data.

How each field in PSI_statement_locker_state is used is described here, not in PSI_statement_locker_state, because usage is specific to the implementation.

Other instrumentations of the PSI interface, (namely, LOCK_ORDER), may choose to use fields differently, or not at all.

Fields in PSI_statement_locker_state are used as follows.

PSI_statement_locker_state::m_class

Statement instrument class. Always populated. Not null.

PSI_statement_locker_state::m_cs_number

Always populated. Character set number, for query text.

PSI_statement_locker_state::m_thread

Thread instrumentation. Always populated. May be null.

PSI_statement_locker_state::m_parent_sp_share

Parent stored program instrumentation. Always populated. May be null.

PSI_statement_locker_state::m_pfs_flags

Flags controlling how collected data is used to feed performance schema tables. Always populated.

Bits have the following semantic:

• STATE_FLAG_BASE indicates that basic statement statistics are to be collected.
• STATE_FLAG_THREAD indicates that per thread statistics are to be populated. When not set, global statistics are populated instead.
• STATE_FLAG_EVENT indicates that detail event data is to be collected.
• STATE_FLAG_TIMED indicates that timing data is collected.
• STATE_FLAG_CPU indicates that cpu data is collected.
• STATE_FLAG_DIGEST indicates that digest data is collected.

In addition, the following filters are implemented:

• STATE_FLAG_BASE depends on PFS_statement_class::m_enabled. That is, column SETUP_INSTRUMENTS.ENABLED is honored.
• STATE_FLAG_THREAD depends on PFS_thread::m_enabled. That is, column THREADS.ENABLED is honored.
• STATE_FLAG_TIMED depends on PFS_statement_class::m_timed. That is, column SETUP_INSTRUMENTS.TIMED is honored.

PSI_statement_locker_state::m_telemetry_scope

These flags are set by the telemetry traces component, to indicate if/how to collect data for telemetry. Never populated, when not compiling with telemetry. Always populated, when compiling with telemetry.

Possible values are:

• 0, to indicate statement traces are not collected.
• TRACE_STATEMENTS, to indicate statement traces are required.

These values are exposed in the mysql_server_telemetry_traces_v1 service, and part of the public mysql_server_telemetry_traces interface.

Subsequent calls to telemetry trace apis can narrow down flags, but can never add more flags.

PSI_statement_locker_state::m_tel_flags

These flags are a translation, in performance schema implementation terms, of interface PSI_statement_locker_state::m_telemetry_scope. Never populated, when not compiling with telemetry traces. Always populated, when compiling with telemetry traces.

Bits have the following semantic:

• STATE_FLAG_BASE indicates that statement statistics are collected.
• STATE_FLAG_THREAD indicates that the thread instrumentation object PFS_thread exists and is not NULL.
• STATE_FLAG_TIMED indicates that timing data is collected.
• STATE_FLAG_CPU indicates that cpu data is collected.
• STATE_FLAG_DIGEST indicates that digest data is collected.
• STATE_FLAG_EVENT indicates that per event data (query text, error message) is collected.

In practice, these flags are not set individually. See STATE_FLAG_STATEMENT_TELEMETRY.

PSI_statement_locker_state::m_collect_flags

Flags controlling data collection. These flags are the union of m_pfs_flags and m_telemetry_scope Always populated.

A value 0 indicates nothing is collected.

PSI_statement_locker_state::m_telemetry_locker

Opaque pointer to a telemetry span inside the telemetry component. Never populated, when not compiling with telemetry. Always populated, when compiling with telemetry. May be NULL.

PSI_statement_locker_state::m_telemetry

Pointer to the telemetry traces component code.

Typed as a void* pointer in public headers, to avoid exposing implementation details. The effective type is guaranteed to be

telemetry_t * 

which is the component entry point loaded by INSTALL COMPONENT <telemetry.so>

Never populated, when not compiling with telemetry traces. Conditionally populated, when compiling with telemetry traces. Not NULL if populated.

This member is initialized only when m_telemetry_locker != nullptr. It points to the telemetry traces component that created the m_telemetry_locker.

When m_telemetry_locker == nullptr, this member is not set.

PSI_statement_locker_state::m_telemetry_session

Pointer to a telemetry session, inside the telemetry component.

Never populated, when not compiling with telemetry traces. Conditionally populated, when compiling with telemetry traces. Not NULL if populated.

This member is initialized only when m_telemetry_locker != nullptr. It points to the telemetry session associated with the m_telemetry_locker.

When m_telemetry_locker == nullptr, this member is not set.

PSI_statement_locker_state::m_controlled_local_size_start PSI_statement_locker_state::m_controlled_stmt_size_start PSI_statement_locker_state::m_total_local_size_start PSI_statement_locker_state::m_total_stmt_size_start

Temporary storage used by the instrumentation to compute the amount of memory used by a sub statement.

Conditionally populated, several conditions apply:

• m_thread != nullptr, the thread instrumentation must exist
• m_collect_flags != 0, data is collected
• m_parent_sp_share != nullptr, the statement is a sub statement.

Used to compute MAX_CONTROLLED_MEMORY and MAX_TOTAL_MEMORY.

PSI_statement_locker_state::m_timer_start

Statement timing information. Conditionally populated, if m_collect_flags != 0. May be 0.

Value set only when bit STATE_FLAG_TIMED is set in m_collect_flags.

Note that m_collect_flags & STATE_FLAG_TIMED can be true, while m_pfs_flags & STATE_FLAG_TIMED can be false, so check the proper flag before using this field.

PSI_statement_locker_state::m_cpu_time_start

CPU timing information. Conditionally populated, if m_collect_flags != 0. May be 0.

Value set only when bit STATE_FLAG_CPU is set in m_collect_flags.

Note that m_collect_flags & STATE_FLAG_CPU can be true, while m_pfs_flags & STATE_FLAG_CPU can be false, so check the proper flag before using this field.

PSI_statement_locker_state::m_no_index_used PSI_statement_locker_state::m_no_good_index_used PSI_statement_locker_state::m_lock_time PSI_statement_locker_state::m_rows_sent PSI_statement_locker_state::m_rows_examined PSI_statement_locker_state::m_created_tmp_disk_tables PSI_statement_locker_state::m_created_tmp_tables PSI_statement_locker_state::m_select_full_join PSI_statement_locker_state::m_select_full_range_join PSI_statement_locker_state::m_select_range PSI_statement_locker_state::m_select_range_check PSI_statement_locker_state::m_select_scan PSI_statement_locker_state::m_sort_merge_passes PSI_statement_locker_state::m_sort_range PSI_statement_locker_state::m_sort_rows PSI_statement_locker_state::m_sort_scan

Optimizer metrics associated with a statement. Conditionally populated, if m_collect_flags & STATE_FLAG_BASE.

PSI_statement_locker_state::m_digest

Query digest. Conditionally populated, if m_collect_flags != 0. May be NULL.

Value set only when bit STATE_FLAG_DIGEST is set in m_collect_flags.

PSI_statement_locker_state::m_schema_name PSI_statement_locker_state::m_schema_name_length

Current schema. Conditionally populated, if m_collect_flags != 0. May be empty.

PSI_statement_locker_state::m_query_sample PSI_statement_locker_state::m_query_sample_length PSI_statement_locker_state::m_query_sample_truncated

Query sample. Conditionally populated, if m_collect_flags != 0. May be empty.

PSI_statement_locker_state::m_secondary

Secondary engine. Conditionally populated, if m_collect_flags != 0.
