# Tests for the performance schema
|
||||
|
||||
# =============
|
||||
# DOCUMENTATION
|
||||
# =============
|
||||
|
||||
# Verify how memory stats are aggregated into various tables
|
||||
#
|
||||
# In the thread dimension:
|
||||
# - memory_summary_by_thread_by_event_name
|
||||
# - memory_summary_by_account_by_event_name
|
||||
# - memory_summary_by_user_by_event_name
|
||||
# - memory_summary_by_host_by_event_name
|
||||
#
|
||||
# Globally:
|
||||
# - memory_summary_global_by_event_name
|
||||
#
|
||||
# The tests are written with the following helpers:
|
||||
# - include/memory_aggregate_setup.inc
|
||||
# - include/memory_aggregate_load.inc
|
||||
# - include/memory_aggregate_cleanup.inc
|
||||
#
|
||||
# Helpers are intended to be used as follows.
|
||||
#
|
||||
# A Typical test t/memory_aggregate_xxx.test will consist of:
|
||||
# --source ../include/memory_aggregate_setup.inc
|
||||
# --source ../include/memory_aggregate_load.inc
|
||||
# --source ../include/memory_aggregate_cleanup.inc
|
||||
# and a t/memory_aggregate_xxx-master.opt file
|
||||
#
|
||||
# Naming conventions for t/memory_aggregate_xxx.test are as follows:
|
||||
# t/memory_aggregate_<account><user><host>
|
||||
#
|
||||
# <account> corresponds to different sizing settings for
|
||||
# the variable performance-schema-accounts-size
|
||||
# - (blank): accounts-size sufficient to represent all records
|
||||
# - no_a: accounts-size set to 0
|
||||
#
|
||||
# <user> corresponds to different sizing settings for
|
||||
# the variable performance-schema-users-size
|
||||
# - (blank): users-size sufficient to represent all records
|
||||
# - no_u: users-size set to 0
|
||||
#
|
||||
# <host> corresponds to different sizing settings for
|
||||
# the variable performance-schema-hosts-size
|
||||
# - (blank): hosts-size sufficient to represent all records
|
||||
# - no_h: hosts-size set to 0
