# To use this script you will need to have installed package python-pyside which
|
||
|
# provides LGPL-licensed Python bindings for Qt. You will also need the package
|
||
|
# libqt4-sql-psql for Qt postgresql support.
|
||
|
#
|
||
|
# The script assumes postgresql is running on the local machine and that the
|
||
|
# user has postgresql permissions to create databases. Examples of installing
|
||
|
# postgresql and adding such a user are:
|
||
|
#
|
||
|
# fedora:
|
||
|
#
|
||
|
# $ sudo yum install postgresql postgresql-server python-pyside qt-postgresql
|
||
|
# $ sudo su - postgres -c initdb
|
||
|
# $ sudo service postgresql start
|
||
|
# $ sudo su - postgres
|
||
|
# $ createuser <your user id here>
|
||
|
# Shall the new role be a superuser? (y/n) y
|
||
|
#
|
||
|
# ubuntu:
|
||
|
#
|
||
|
# $ sudo apt-get install postgresql python-pyside.qtsql libqt4-sql-psql
|
||
|
# $ sudo su - postgres
|
||
|
# $ createuser -s <your user id here>

|
||
|
#
|
||
|
# Tables:
|
||
|
#
|
||
|
# The tables largely correspond to perf tools' data structures. They are largely self-explanatory.
|
||
|
#
|
||
|
# samples
|
||
|
#
|
||
|
# 'samples' is the main table. It represents what instruction was executing at a point in time
|
||
|
# when something (a selected event) happened. The memory address is the instruction pointer or 'ip'.
|
||
|
#
|
||
|
# calls
|
||
|
#
|
||
|
# 'calls' represents function calls and is related to 'samples' by 'call_id' and 'return_id'.
|
||
|
# 'calls' is only created when the 'calls' option to this script is specified.
|
||
|
#
|
||
|
# call_paths
|
||
|
#
|
||
|
# 'call_paths' represents all the call stacks. Each 'call' has an associated record in 'call_paths'.
|
||
|
# 'calls_paths' is only created when the 'calls' option to this script is specified.
|
||
|
#
|
||
|
# branch_types
|
||
|
#
|
||
|
# 'branch_types' provides descriptions for each type of branch.
|
||
|
#
|
||
|
# comm_threads
|
||
|
#
|
||
|
# 'comm_threads' shows how 'comms' relates to 'threads'.
|
||
|
#
|
||
|
# comms
|
||
|
#
|
||
|
# 'comms' contains a record for each 'comm' - the name given to the executable that is running.
|
||
|
#
|
||
|
# dsos
|
||
|
#
|
||
|
# 'dsos' contains a record for each executable file or library.
|
||
|
#
|
||
|
# machines
|
||
|
#
|
||
|
# 'machines' can be used to distinguish virtual machines if virtualization is supported.
|
||
|
#
|
||
|
# selected_events
|
||
|
#
|
||
|
# 'selected_events' contains a record for each kind of event that has been sampled.
|
||
|
#
|
||
|
# symbols
|
||
|
#
|
||
|
# 'symbols' contains a record for each symbol. Only symbols that have samples are present.
|
||
|
#
|
||
|
# threads
|
||
|
#
|
||
|
# 'threads' contains a record for each thread.
|
||
|
#
|
||
|
# Views:
|
||
|
#
|
||
|
# Most of the tables have views for more friendly display. The views are:
|
||
|
#
|
||
|
# calls_view
|
||
|
# call_paths_view
|
||
|
# comm_threads_view
|
||
|
# dsos_view
|
||
|
# machines_view
|
||
|
# samples_view
|
||
|
# symbols_view
|
||
|
# threads_view
|
||
|
#
|
||
|
# More examples of browsing the database with psql:
|
||
|
# Note that some of the examples are not the most optimal SQL query.
|
||
|
# Note that call information is only available if the script's 'calls' option has been used.
|
||
|
#
|
||
|
# Top 10 function calls (not aggregated by symbol):
|
||
|
#
|
||
|
# SELECT * FROM calls_view ORDER BY elapsed_time DESC LIMIT 10;
|
||
|
#
|
||
|
# Top 10 function calls (aggregated by symbol):
|
||
|
#
|
||
|
# SELECT symbol_id,(SELECT name FROM symbols WHERE id = symbol_id) AS symbol,
|
||
|
# SUM(elapsed_time) AS tot_elapsed_time,SUM(branch_count) AS tot_branch_count
|
||
|
# FROM calls_view GROUP BY symbol_id ORDER BY tot_elapsed_time DESC LIMIT 10;
|
||
|
#
|
||
|
# Note that the branch count gives a rough estimation of cpu usage, so functions
|
||
|
# that took a long time but have a relatively low branch count must have spent time
|
||
|
# waiting.
|
||
|
#
|
||
|
# Find symbols by pattern matching on part of the name (e.g. names containing 'alloc'):
|
||
|
#
|
||
|
# SELECT * FROM symbols_view WHERE name LIKE '%alloc%';
|
||
|
#
|
||
|
# Top 10 function calls for a specific symbol (e.g. whose symbol_id is 187):
|
||
|
#
|
||
|
# SELECT * FROM calls_view WHERE symbol_id = 187 ORDER BY elapsed_time DESC LIMIT 10;
|
||
|
#
|
||
|
# Show function calls made by function in the same context (i.e. same call path) (e.g. one with call_path_id 254):
|
||
|
#
|
||
|
# SELECT * FROM calls_view WHERE parent_call_path_id = 254;
|
||
|
#
|
||
|
# Show branches made during a function call (e.g. where call_id is 29357 and return_id is 29370 and tid is 29670)
|
||
|
#
|
||
|
# SELECT * FROM samples_view WHERE id >= 29357 AND id <= 29370 AND tid = 29670 AND event LIKE 'branches%';
|
||
|
#
|
||
|
# Show transactions:
|
||
|
#
|
||
|
# SELECT * FROM samples_view WHERE event = 'transactions';
|
||
|
#
|
||
|
# Note transaction start has 'in_tx' true whereas, transaction end has 'in_tx' false.
|
||
|
# Transaction aborts have branch_type_name 'transaction abort'
|
||
|
#
|
||
|
# Show transaction aborts:
|
||
|
#
|
||
|
# SELECT * FROM samples_view WHERE event = 'transactions' AND branch_type_name = 'transaction abort';
|
||
|
#
|
