# 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 qt-postgresql |
|
# $ sudo su - postgres -c initdb |
|
# $ sudo service postgresql start |
|
# $ sudo su - postgres |
|
# $ createuser -s <your user id here> # Older versions may not support -s, in which case answer the prompt below: |
|
# Shall the new role be a superuser? (y/n) y |
|
# $ sudo yum install python-pyside |
|
# |
|
# Alternately, to use Python3 and/or pyside 2, one of the following: |
|
# $ sudo yum install python3-pyside |
|
# $ pip install --user PySide2 |
|
# $ pip3 install --user PySide2 |
|
# |
|
# ubuntu: |
|
# |
|
# $ sudo apt-get install postgresql |
|
# $ sudo su - postgres |
|
# $ createuser -s <your user id here> |
|
# $ sudo apt-get install python-pyside.qtsql libqt4-sql-psql |
|
# |
|
# Alternately, to use Python3 and/or pyside 2, one of the following: |
|
# |
|
# $ sudo apt-get install python3-pyside.qtsql libqt4-sql-psql |
|
# $ sudo apt-get install python-pyside2.qtsql libqt5sql5-psql |
|
# $ sudo apt-get install python3-pyside2.qtsql libqt5sql5-psql |
|
# |
|
# An example of using this script with Intel PT: |
|
# |
|
# $ perf record -e intel_pt//u ls |
|
# $ perf script -s ~/libexec/perf-core/scripts/python/export-to-postgresql.py pt_example branches calls |

|
# To browse the database, psql can be used e.g. |
|
# |
|
# $ psql pt_example |
|
# pt_example=# select * from samples_view where id < 100; |
|
# pt_example=# \d+ |
|
# pt_example=# \d+ samples_view |
|
# pt_example=# \q |
|
# |
|
# An example of using the database is provided by the script |
|
# exported-sql-viewer.py. Refer to that script for details. |

# |
|
# 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'; |
|
# |
|
# To print a call stack requires walking the call_paths table. For example this python script: |
|
# #!/usr/bin/python2 |
|
# |
|
# import sys |
|
# from PySide.QtSql import * |
|
# |
